Very new to programming.
This bit of my program accepts two strand of DNA as input and output them in a double helix drawing. The problem is, if one of the two input strand is longer than the other, i will receive error.
So I thought, is it possible that if strand[add] is non-existent anymore, replace it with *?
#include <iostream>
#include <string>
#include <conio.h>
using namespace std;
void helix(string &strand1, string &strand2)
{
int nucleo;
int length;
if (strand1.length() >= strand2.length())
{
length = strand1.length();
}
else
{
length = strand2.length();
}
int add;
for (int add = 0; add <= length - 1; add++)
{
if (add > 7)
{
nucleo = add % 8;
}
else
{
nucleo = add;
}
if (nucleo == 0)
{
cout << " " << strand1[add] << "---"<<strand2[add] << endl;
}
else if (nucleo == 1)
{
cout << " " << strand1[add] << "------" << strand2[add] << endl;
}
else if (nucleo == 2)
{
cout << " " << strand1[add] << "------" << strand2[add] << endl;
}
else if (nucleo == 3)
{
cout << " " << strand1[add] << "---" << strand2[add] << endl;
cout << " *" << endl;
}
else if (nucleo == 4)
{
cout << " " << strand2[add]<<"---" << strand1[add] << endl;
}
else if (nucleo == 5)
{
cout << " " << strand2[add]<<"------" << strand1[add] << endl;
}
else if (nucleo == 6)
{
cout << " " << strand2[add]<<"------" << strand1[add] << endl;
}
else if (nucleo == 7)
{
cout << " " << strand2[add]<<"-----" << strand1[add] << endl;
cout << " *" << endl;
}
}
}
int main()
{
string strand1,strand2;
cout << "ENTER STRAND:" << endl;
cin >> strand1;
cout << "ENTER STRAND:" << endl;
cin >> strand2;
helix(strand1,strand2);
_getch();
return 0;
}
I was hoping I could still show the longer strand even if the other side of the strand is empty(want to put *) like this :imgur.com/t7riVrS
I think you inverted the legnth test, it should be:
//if (strand1.length() >= strand2.length())
if (strand1.length() < strand2.length())
{
length = strand1.length();
}
else
{
length = strand2.length();
}
Edit:
If you want it fill one the string with '*', replace the code above with:
while (strand1.length() < strand2.length())
{
strand1 += "*";
}
while (strand1.length() > strand2.length())
{
strand2 += "*";
}

So i have to code the dice game LCR for a final prject but am having some trouble. First off, I know the code is sloppy and really redundant, that's why im looking for help. I couldn't figure out how to connect the 'chips' int vector and 'name' array into the player.h file. I basically need help writing methods for the chip passing to make the code less redundant. But another problem of mine is having the game loop until just one person has chips. Thanks for any help or advice.

To be fair, I'm quite new to programming, but I have been working on this project for days and kept running into conatiner problems and storing the name and chip values independently. So i've tried a lot of different things, probably not correctly though so I'm open to anything.
So I want to search my array for my data and move back and forth, so this is what i came up with, however this isn't working, can there be a better way to do this ? I tried to google some tips however I wasn't finding a suitable way to do this...
Can binary search be used to do this same thing ?
struct student
{
int stid = NULL;
char stname[15] = "NULL";
int grades = NULL;
string date = NULL;
};
int main()
{
int choose = 0;
int stid = 0;
int array = 1;
struct student s[1] = { 001, "Sara", "123456", "Canada", "02/01/2019" };
while (choose != 4)
{
cout << "1. Add\n";

Thank you for helping.
I have been receiving an issue that I do not understand. The issue is:
Run-Time Check Failure #3 - The variable 'win' is being used without being initialized.
I am struggling to comprehend where my error is within the code. From what I understand the run time error comes from win not being initialized meaning it hasn't been used or set, however, it clearly is set in the fightScene() function.

All I can see that sets win is this part of the code,
if (cCharacter[1].getHealth() < 0) {
ran_pick = 0;
win = 1;
}
else if (cCharacter[1].getHealth() > 0) {
cout << "\n\t\t<" << cCharacter[1].getName() << "'s turn>" << endl;
win = 0;
}
However, if cCharacter[1].getHealth()==0, win will be left unset.
I study C ++ and try to create the first game. Here's the code:
#include <iostream>
#include <string>
using namespace std;
void info () {
int LVL = 1;
int money = 1000;
int EXP = 0;
int work = 200;
int learn = 15;
int k = 0;
}
void menu ()
{
info ();
char menu_items;
cout << "Choose action: " << "\n" << "1. Work" << "\n" << "2. Learn" << endl;
cin >> k;
if (k == 1){
int money = money + work;
cout << "U worked (+ "<< money << " dollars)" << "\n" << endl;
} if (k == 2) {
int EXP = EXP + learn;
cout << "U learned (+ " << EXP << " EXP)" << "\n" << endl;
} else {
cout << "ERROR" << endl;
}
}
int main()
{
info ();
while (LVL == 10) {
cout << "End game!";
}
while (LVL != 10) {
cout << "Your data: " << "\n" << "Money: " << money << "\n" << "EXP: " << EXP << "\n" << "LVL: " << LVL << "\n" << endl;
menu ();
}
}
Please correct the following:
1) The cyclic output data after rewrite
2) Proper cycle add money and experience when choosing one of the following actions
Info should probably be a class or struct. You only want to instantiate it once, and persist the values over your calls.
One option might be:
#include <iostream>
#include <string>
using namespace std;
struct info {
int lvl = 1;
int money = 1000;
int exp = 0;
const int work = 200;
const int learn = 15;
};
int main()
{
info i;
string k;
while (i.lvl < 10)
{
cout << "Your data: " << "\n" << "Money: " << i.money << "\n" << "EXP: " << i.exp << "\n" << "LVL: " << i.lvl << endl;
cout << "Choose action: " << "\n" << "1. Work" << "\n" << "2. Learn" << endl;
cin >> k;
if (k == "1")
{
i.money += i.work;
cout << "You worked (+ " << i.work << " dollars, now " << i.money << ")" << endl;
}
else if (k == "2")
{
i.exp += i.learn;
cout << "You learned (+ " << i.learn << " EXP, now " << i.exp << ")" << endl;
}
else
{
cout << "ERROR" << endl;
}
}
cout << "You won!" << endl;
}
#include <iostream>
#include <string>
using namespace std;
void menu()
{
int money = 1000;
int EXP = 0;
int work = 200;
int learn = 15;
int k = 0;
cout << "Choose action: \n 1. Work \n 2. Learn "<< endl;
cin >> k;
if (k == 1){
money =money + work;
cout << "U worked (+ " << money << " dollars)" << "\n" << endl;
} if (k == 2) {
EXP = EXP + learn;
cout << "U learned (+ " << EXP << " EXP)" << "\n" << endl;
}
else {
cout << "ERROR" << endl;
}
}
int main()
{
int money = 1000;
int LVL = 1;
int EXP = 0;
while (LVL == 10) {
`cout << "End game!"; `
}
while (LVL != 10) {
cout << "Your data: " << "\n" << "Money: " << money << "\n" << "EXP: " << EXP << "\n" << "LVL: " << LVL << "\n" << endl;

I'm solving some C++ problems from ebooks. I made this C++ program but it isn't working properly. I've 2 problems:
Even after applying the forumla (votePercentage = firstAnswer/totalVotes*100;) it isn't showing the output, but only 0.
The program should display the bar chart, how am I suppose to do that? Any hints, reference or solution will be appreciated.
Here is my code:
/*
* Write a program that provides the option of tallying up the
* results of a poll with 3 possible values.
* The first input to the program is the poll question;
* the next three inputs are the possible answers.
* The first answer is indicated by 1, the second by 2, the third by 3.
* The answers are tallied until a 0 is entered.
* The program should then show the results of the poll—try making
* a bar graph that shows the results properly scaled to fit on
* your screen no matter how many results were entered.
*/
#include <iostream>
#include <string>
void startPoll (void);
void showPoll (void);
void pollCheck (void);
std::string pollQuestion, answer1, answer2, answer3;
int pollChoice, firstAnswer, secondAnswer, thirdAnswer;
int main (void)
{
int totalVotes = 1;
float votePercentage;
startPoll();
showPoll();
for(;;totalVotes++)
{
if (pollChoice == 1)
{
firstAnswer = firstAnswer + 1;
}
else if (pollChoice == 2)
{
secondAnswer++;
}
else if (pollChoice == 3)
{
thirdAnswer++;
}
else
{
std::cout << "==============*======*======*==============\n"
<< " RESULT \n"
<< "==============*======*======*==============\n"
<< "Question: " << pollQuestion << "\n"
<< "Total Votes: " << totalVotes << "\n";
votePercentage = (firstAnswer/totalVotes)*100;
std::cout << answer1 << ": " << firstAnswer << " votes. | " << votePercentage << "\n";
votePercentage = secondAnswer/totalVotes*100;
std::cout << answer2 << ": " << secondAnswer << " votes. | " << votePercentage << "\n";
votePercentage = thirdAnswer/totalVotes*100;
std::cout << answer3 << ": " << thirdAnswer << " votes. | " << votePercentage << "\n";
return 0;
}
std::cout << "\nEnter your vote again\nOR\nuse 0 to show the results.\n";
std::cin >> pollChoice;
}
std::cout << "Error: Something went wrong!\n";
}
void startPoll (void)
{
std::cout << "Enter your poll question:\n";
getline (std::cin, pollQuestion, '\n');
std::cout << "Enter answer 1:\n";
getline (std::cin, answer1, '\n');
std::cout << "Enter answer 2:\n";
getline (std::cin, answer2, '\n');
std::cout << "Enter answer 3:\n";
getline (std::cin, answer3, '\n');
}
void showPoll (void)
{
std::cout << "==============|======|======|==============\n"
<< " POLL \n"
<< "==============|======|======|==============\n"
<< pollQuestion << "\n"
<< "1. " << answer1 << "\n"
<< "2. " << answer2 << "\n"
<< "3. " << answer3 << "\n\n"
<< "Enter 1,2 or 3:\n\n";
std::cin >> pollChoice;
pollCheck();
}
void pollCheck (void)
{
if (pollChoice != 1 && pollChoice != 2 && pollChoice != 3)
{
std::cout << "Wrong choice entered! Please try again.\n\n";
return showPoll();
}
}
You need to take care that integer/integer = integer. In your case, changing
(firstAnswer/totalVotes)*100
to
(1.0*firstAnswer/totalVotes)*100
or
(firstAnswer*100.0/totalVotes)
should work. They all give a floating point result.
Well, the solution for the Bar Chart could be the following:(Not written by me) I think thats very self explaining because its really basic
void line (int n, char c)
{
// this is the loop for n
for (int i = 0; i < n; i++)
cout << c << endl;
}
Here is my solution, you can see how I made the bars work by reading the comments.
#include <iostream>
using namespace std;
int main()
{
int a = 0;
int b = 0;
int c = 0;
cout << "What is your favorite animal? 1 Cat, ";
cout <<"2 Dog, 3 Fish, 0 Count votes" << endl;
//Choice counter
while (true)
{
int choice;
cout << "Choice: ";
cin >> choice;
if(choice == 1)
a++;
else if(choice == 2)
b++;
else if(choice == 3)
c++;
else if(choice == 0)
break;
else
continue;
}
cout << endl << " 1: " << a << endl;
cout << " 2: " << b << endl;
cout << " 3: " << c << endl;
cout << endl << "1\t" << "2\t" << "3\t" << endl;
//Finds the max voted option
int max = 0;
if(a > b && a > c)
max = a;
else if(b > c && b > a)
max = b;
else if(c > a && c > b)
max = c;
/* If the max voted option is bigger than 10, find by how much
we have to divide to scale the graph, also making 10 bar
units the max a bar can reach before scaling the others too */
int div =2;
if(max > 10)
{
do
{
max = max/div;
if(max < 10)
break;
div++;
}while(true);
}else
div = 1;
//Sets the final number for the bars
a=a/div;
b=b/div;
c=c/div;
if(a==0)
a++;
if(b==0)
b++;
if(c==0)
c++;
//Creates the bars
while(true)
{
if(a>0)
{
cout << "[]" << "\t";
a--;
}else
cout << " ";
if(b>0)
{
cout << "[]" << "\t";
b--;
}else
cout << " ";
if(c>0)
{
cout << "[]" << "\t";
c--;
}else
cout << " ";
cout << endl;
if(a==0 && b==0 && c==0)
break;
}
}
