how i do this?

Question

i wanna do the program that tell the user to input’=‘ to stop and calculate the sum. but i dont know ho to write it on c++

Answer 1

you can't cin to an int if you want to get the "=". do the integer casting (stoi) during addition. cin to a string.

#include <iostream>
#include <string>
using namespace std;

int main()
{
int sum;
string num;
cout<<"Enter any number and press = to calculate the sum "<<endl;
while(true){
cout<<"Enter number : ";
cin>>num;
if(num!="=")
sum+=stoi(num);
else{
cout << "Sum = " << sum;
break;
}
}
}

Answer 2

#include <iostream>
#include <conio.h>
#include <string>
using namespace std;

int main()
{
int num, sum;
const char ESC = '=';

cout<<"Enter any number and press = to calculate the sum "<<endl;
cout<<"Enter number : ";
cin>>num;

while(num>=0 || num<=0){
sum+=num;

cout<<"Enter number : ";
cin>>num;

}
if( num == ESC ){
cout << "Sum = " << sum;
}
}

how i can improve my code?
