Why does this code work in the code playground but not in Codeblocks?

Question

#include <iostream>
using namespace std;

int main() {

int score;

cout << "Please enter score" << endl;
cin >> score;

if(score>=70) { cout << "You got an A*"; }
if (score>=60 && score<70) { cout << "You got an A"; }
if (score>=50 && score<60) { cout << "You got a B"; }
if (score>=40 && score<50) { cout << "You got a C";}
if (score<40) { cout << "You have failed";}

return 0;
}

In code blocks, for example when I input 50 I get nothing back

(Please enter score
50

Process returned 0 (0x0) execution time : 5.076 s
Press any key to continue. )

Whereas a score of 55 outputs Grade: A

Please could someone tell me whats going on

Answer 1

Hmm it seems that in Code Blocks, the program automatically closes the command prompt (or terminal) once the program is finished. Try putting system("PAUSE"); or getchar() before your return to keep the command prompt open.

Thanks for response! Although code blocks doesn't seem to like it..
