Hello,
I know that this is an old thread, but for me it’s new..
I faced this situation where the screen quit instantly, and I knew now that using system() and cin.ignore() aren’t good solutions
So, I used the pause(); function, and it goes ok unless there is a data input (cin>>xxx; ) even if I have to display a message after inputting the data
For example:
#include <iostream>
using namespace std;
#include <limits>
void pause() {
std::cout << "Press ENTER to continue... ";
std::cin.ignore( std::numeric_limits<streamsize>::max(), '\n' );
}
int main() {
int num1, num2;
cout<<"Enter two numbers to calculate: \nnum1= ";
cin>>num1;
cout<<"\nnum2= ";
cin>>num2;
cout<<"\nI’ve got ur numbers!!";
pause();
return 0;
}Here, once I enter num2 and hit the Enter button, the “Press Enter to…” with the “I’ve got…” messages appears but the screen closes instantly when sometimes I couldn’t even see the messages because it’s too fast
However, when I remove all the cin(s), the screen shows me the cout(s) messages and waits for the key press to terminate!!
Could anyone give me an explanation for this situation??
