I am making a menu for a store with 4 options; add product, delete product, see table of created products and exit the program.
I finished the option to add products and exit, they both work fine.
Now I have to make the option to see the product table, supposedly I had already finished it but I noticed a problem ...
The first time I go in to see the product table, it prints it to me normally, like this.
enter image description here
But when I go to the menu and go back to the product table, it prints it like this.
enter image description here
Like I said, it only prints it right the first time I see it, then it prints it wrong.
Do you know how I can solve it?
This is the part of the code where I print the product table.
void table()
{
int c = k, m = 7;
system("cls");
cout << endl;
cout << "Table of created products";
cout << endl;
cout << endl;
cout << " number of order ";
cout << "| Name of product |";
cout << " Product code |";
cout << " Amount |";
cout << " Unit price |";
cout << " Subtotal |";
cout << " IVA |";
cout << " total price |";
cout << endl;
cout << "-------------------------------------------------------------------------------------------------------------------------------------";
cout << endl;
for (int L = 2; L <= c; L++)
{
cout << " ";
cout << "| |";
cout << " |";
cout << " |";
cout << " |";
cout << " |";
cout << " |";
cout << " |";
cout << endl;
cout << "-------------------------------------------------------------------------------------------------------------------------------------";
cout << endl;
}
for (int h = 1; h < c; h++)
{
gotoxy(8, m);
cout << product[h].numor;
gotoxy(20, m);
cout << product[h].descr;
gotoxy(52, m);
cout << product[h].cod;
gotoxy(70, m);
cout << product[h].cant;
gotoxy(83, m);
cout << "$" << product[h].preuni;
gotoxy(96, m);
cout << "$" << product[h].subt;
gotoxy(107, m);
cout << "$" << product[h].IVA;
gotoxy(119, m);
cout << "$" << product[h].total;
m = m + 4;
}
cout << "\n\n\n";
system("pause");
system("cls");
}

Thank you very much in advance :)
The main reason for this problem is that after the size of the console changes, the position of the symbols you draw has also changed. At the same time, the line break determined by cout<<endl; also has a problem. For example, after the window becomes larger, the line length of the console becomes larger, but cout<<endl; is still the original line length.
However, there is no good solution. I suggest you directly set the console size and m=5, m=m+2.

I am working on the "checkout" process of my vending machine code. I want to write it so that the program will keep asking for the amount needed from the user until all the money is entered. However, this code segment does not completely work.
"Checkout" Segment of Code:
while (money < total) {
float amountOwed = total - money;
cout << "Please insert another $" << amountOwed << endl;
cout << "Enter amount: $" << flush;
float payment;
cin >> payment;
}
if (money > total) {
float change = money - total;
cout << "Thank you! You have $" << change << " change." << endl;
}
if (money == total) {
cout << "Thank you! Have a nice day!." << endl;
}
Full code below:
#include <iostream>
#include <iomanip>
using namespace std;
string menuItems[5] = { "Popcorn", "Coconut Clusters" , "Granola Bar" , "Trail Mix" , "Chocolate" };
float cost[5] = { 2, 3, 2.50, 1.50, 1 };
void vendingMachine() {
for (int i = 0; i < 5; i++)
cout << i + 1 << ". " << menuItems[i] << ": $" << cost[i] << endl;
}
int main() {
cout.precision(2);
cout << std::fixed;
cout << "Vending Machine" << endl;
cout << "----Items------" << endl;
vendingMachine();
cout << "Enter 0 to checkout" << endl;
float total;
total = 0;
int item;
do {
cout << "Enter your selection: " << flush;
cin >> item;
item = item - 1;
//here will be printed : $0 has been added to cart even if you pressed 0 and what to escape
//is it possible to fix this??
cout << menuItems[item] << ": $" << cost[item] << " has been added to cart." << endl;
total = total + cost[item];
} while (item != -1);
cout << " " << endl;
cout << "Proceding to checkout..." << endl;
cout << "========================" << endl;
cout << "Amount due: $" << total << endl;
cout << "Insert money here: $" << flush;
float money;
cin >> money;
while (money < total) {
float amountOwed = total - money;
cout << "Please insert another $" << amountOwed << endl;
cout << "Enter amount: $" << flush;
float payment;
cin >> payment;
}
if (money > total) {
float change = money - total;
cout << "Thank you! You have $" << change << " change." << endl;
}
if (money == total) {
cout << "Thank you! Have a nice day!." << endl;
}
return 0;
}
In this loop:
while (money < total) {
you are not modifying money or total so the loop will never exit.
You probably want to update money like this:
while (money < total) {
// ...
cin >> payment;
money += payment;
}
I am currently writing a code where in my main function I am just calling other functions. I am attempting to reloop back to the begining so the user can run the program again. The main function is just to call functions so my question is I know it is not possible to go back to the main function, but is it possible to create a function that will loop all other functions again? I feel as though I tried everything and continue to get infinite loops. I attached my code.

As you know, in main you can just have a while loop with the code you want to repeat inside it:
int main()
{
// this will loop forever, until you explicitly break or return
while (true) {
// your code here
}
}
... but since you are constrained by the artificial limitation of only having function calls in main...
void run()
{
// this will loop forever, until you explicitly break or return
while (true) {
// your code here
}
}
int main()
{
run();
}
How do I make a function that will terminate the program if the user says e, and loop if the user presses l at any time?
How do I make the program reask the user for number input if the user inputs letters instead of numbers? Currently, the program terminates when I input blah, for instance. My obstacle is the bool die definition: I'm not sure how to use bool die to loop instead of die (my teacher required bool die usage.)
#include <iostream>
#include <string>
#include <stdlib.h>
using namespace std;
bool die(const string & msg);
int main() {
// declaring variables:
unsigned QUARTERS;
unsigned DIMES;
unsigned NICKELS;
unsigned PENNIES;
double total;
cout << "********************************************************" << endl;
cout << " Welcome to Crazy Coin Counter! " << endl;
cout << "********************************************************" << endl << endl;
// user input:
//QUARTERS
do {
cout << " # QUARTERS: ";
cin >> QUARTERS;
if (cin){
if (QUARTERS < 1000)
cout << " --> Input Successful!" << endl;
}
else die(" --> :( Input Unsuccessful!");
cout << " You must put in less than 1000 quarters! Please try again." << endl << endl << endl;
} while (QUARTERS >= 1000 );
//DIMES
do{
cout << endl << " # DIMES: ";
cin >> DIMES;
if (cin){
if (DIMES < 1000)
cout << " --> Input Successful!" << endl;
}
else die(" --> :( Input Unsuccessful!");
if (DIMES >= 1000)
cout << " You must put in less than 1000 dimes! Please try again." << endl << endl << endl;
} while (DIMES >= 1000);
//NICKELS
do {
cout << endl << " # NICKLES: ";
cin >> NICKELS;
if (cin){
if (NICKELS < 1000)
cout << " --> Input Successful!" << endl;
}
else die(" --> :( Input Unsuccessful!");
if (NICKELS >= 1000)
cout << " You must put in less than 1000 nickels! Please try again." << endl << endl << endl;
} while (NICKELS >= 1000);
//PENNIES
do {
cout << endl << " # PENNIES: ";
cin >> PENNIES;
if (cin){
if (PENNIES < 1000)
cout << " --> Input Successful!" << endl;
}
else die(" --> :( Input Unsuccessful!");
if (PENNIES >= 1000)
cout << " You must put in less than 1000 pennies! Please try again." << endl;
} while (PENNIES >= 1000);
// calculations:
total = (QUARTERS * 0.25) + (DIMES * 0.1) + (NICKELS * 0.05) + (PENNIES * 0.01);
// output:
cout << endl <<endl<< "Congrats! You have $" << total << " worth of coins! " << endl << endl << endl;
}
// function definition
bool die(const string & msg){
cout << " " << msg << endl;
exit(EXIT_FAILURE);
}
Try something like this:
while ( true ) // Loop forever
{
cout << "Enter 'e' to exit:";
std::string answer;
getline(cin, answer);
if (answer == "e")
{
break; // Break out of the loop
}
else
{
cout << "\nWrong answer.\n";
continue; // The continue would start at the top of the loop.
}
}
There are many other techniques that you can find by searching StackOverflow for "c++ terminate loop".
Edit 1: Checking numerical input
The simplest method for checking numerical input is to test the result of inputting the number:
unsigned int quarters; // Using unsigned because quantities can't be negative.
cout << "Enter number of quarters: ";
if (cin >> quarters) // Input and test in same statement.
{
cout << "Your total is " << (quarters * 0.25) << "\n";
}
else
{
// Handle incorrect input
cout << "Invalid input, try again.\n";
}

These two statements do exactly nothing, and are likely the source of the warning the compiler is giving you:
account1.endBal;
account2.endBal;
Furthermore, I think you need to actually capture the return value of GetTransfer() here, perhaps into transferAmt:
GetTransfer();
You probably need to rethink this entire while loop, especially taking into account how transferAmt relates to account1.endBal:
while (account1.endBal < 0)
{
cout << "Error. Account balance can not be negative." << endl;
GetTransfer();
if (account1.endBal < 10)
{
cout << "Warning. Account balance will be below $10.00 " << endl;
}
}
For example, you don't want to update endBal until you know the transfer will succeed. Furthermore, your low-balance warning is in completely the wrong place.
