Add a countdown timer to a math program quiz - c++

I am trying to add a countdown timer to this program. I would like the timer to start when the first math fact question is asked and upon expiration i want the program to give the grade. What's the code to do this in c++ if possible?

The task is quite hard, but if you dare trying, I suggest doing it in two steps:
Implement inaccurate solution: timer expiration is checked between queries to user.
If there is some time left, next question is asked, otherwise statistics is shown. So program always waits for user input on the last question despite timer has run out. Not what exactly quizzes look like, but good move to start with.
Method: before starting quiz save current time, before each question take delta between saved time and current one and compare with time limit. Example with chrono (starting from C++11), example with oldschool clock
Add middle-question interruption
This part requires function, which will wait for user input not longer, than specified amount of time. So instead of using std::cin() you'll need to calculate amount of time left (time limit minus delta between cur time and start time) and call some sort of cin_with_timeout(time_left).
The hardest thing is implementing cin_with_timeout(), which requires solid knowledge of multithreading and thread synchronization. Great inspiration can be found here, but it is direction to start thinking rather than complete solution.

C++ Left Center Right Dice Game (Game Loop and connecting vectors/arrays to classes/header files)

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.

Why does the if statement is always the else part even if the if is true?

I'm having a problem with the if statement at the end.
**if the sum of the cubs of the number a user inputs, is equal to the number itself, say "....". Else, say "....." **
The problem is that it always jumps the if part to the else.
Its a task from the uni, no homework or nothing, just training. IF you have suggestions on how to better I would appreciate that too.
Thank you!

return 0;
} ```
When the if-part is entered, the else-part won't be entered any more. Note that your if/else is not surrounded by a loop. So when control passes by once, e.g. when having entered n==0, then it has passed by and won't step into neither the if nor the else-part a second time.
Try something like
while (n==0) {
cout << "Choose another number -> ";
cin >> n;
}
// continue here; n is != 0

Random Guessing Game in C++

My assignment is to create a guessing game where the computer guesses my number and one where I guess the computer's number. I have my code written out but It's incomplete. I want to create a menu so the user can choose which game he wants to play, and also i am having trouble joining the two programs into one so they both will run. Can someone please assist me. The first game works fine but from there I really don't know what I'm doing.

int userGuess = 0;
int systemNum = 0;
int systemGuess = 0;
cout << "Welcome to the Guessing Game!" << endl;
cout << "Enter a 2 to play Game 1 or a 3 to play Game 2. Or enter 4 to quit." << endl;
cin >> num;
if (num == 2)
{
cout << "Welcome to Game 1!" << endl;
cout << "User, enter a random number between " << min << " and " << max << " : "; cin >> userNum;

Make the two games two distinct functions (each with its own local variables), create a third one that is a loop that prompts for the games (and break when "quit" is selected), and call the corresponding function, then call the third one from main.
You can use if...else :
cout << "Welcome to the Guessing Game!" << endl;
cout << "Enter a 2 to play Game 1 or a 3 to play Game 2. Or enter 4 to quit." << endl;
cin >> num;
if (num == 2)
{//game1
}
else if(num==3)
{//game2
}
else if(num==4)
{return 0;
}else
{
cout<<"Invalid choice!";
system("pause");
return 1;
}
//print highscores
system("pause");
return 0;

C++ program to display votes in percentage not showing correct result

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.

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;
}
}

how to make a continous loop with second while statement

okay here is my code for a game called pig. I having trouble because the code for the computers turn will only got through one time and once the second turn is reached the first line is only printed. is there any soluction to this or am I just screwed?
`int main () {
int humanTurn=0;
int humanTotalScore=0;
int computerTotalScore=0;
int computerTurn=3;
float diceRoll = 0;
int score = 0;
int computerScore = 0;
int answer = 0;
int humanScore = 0;
int pause = 0;
float computerDiceRoll = 0;
srand(time(0));
cout << "Welcome to the game of pig, the first player to reach to 100 wins."<< endl;
cout << "if you roll a one no score will be recorded and your turn will go the computer"<< endl;
cout << " If you choose to hold, the total score accumilated will be recorded" << endl;
while ((humanTotalScore < 100) && (computerTotalScore < 100)) {
cout << endl;
cout << endl;
cout << "press 1 to roll or 2 to save your score: ";
cin >> answer;
for (int i=0; i<1; i++) {
diceRoll = rand() % 6 + 1;
}
if ((diceRoll > 1) && ( answer == 1)){
cout << endl;
cout << endl;
cout << "your current roll is: " << diceRoll << endl;
cout << endl;
cout << endl;
score += diceRoll;
cout << "Score for this turn is: " << score << endl;
cout << "your total score is: " << humanTotalScore << endl;
cout << endl;
cout << endl;
}
else if (answer == 2){
cout << "your score of: " << score << " will be saved" << endl;
humanTotalScore += score;
score = 0;
}
else {
cout << endl;
cout << endl;
cout << "you rolled a ONE. You lose your turn and any points that were with it" <<endl;
cout << endl;
cout << endl;
score = 0;
computerTurn = score;
}
if ((computerTurn == 0) || (answer == 2)){
computerDiceRoll = rand() % 6 + 1;
here is code that is giving me loop problems.
while ((computerDiceRoll > 1)&& (computerScore <= 20)){
if (computerDiceRoll == 1){
computerScore = 0;
computerTurn = 1;
cout << "Computer rolled a ONE, it is now your turn." << endl;
}
computerDiceRoll = rand() % 6 + 1;
cout << endl;
cout << endl;
cout << "computers roll is : " << computerDiceRoll << endl;
cout << endl;
cout << endl;
computerScore += computerDiceRoll;
if (computerScore >20){
computerTotalScore += computerScore;
computerTurn = 1;
}
cout << "computer current score is : " << computerScore << endl;
cout << "computer total score is: " << computerTotalScore << endl;
cout << endl;
cout << endl;
}
}
}
} `
