简单的C程序未在Eclipse中显示输出

Question

A few days back I installed Eclipse ide and also the CDT plugin therein for C and C++ development. Also made the necessary settings. Also tried a simple C program of adding two integers. Surprisingly, no output was shown in the terminal, but when the program was terminated it showed a wrong output of 0 .

The program was this:

#include <stdio.h>

int main(){
  int a, b;
  printf("Enter an integer: "); scanf("%d", &a);
  printf("Enter another integer: "); scanf("%d", &b);
  printf("Sum = %d", (a+b));
  return 0;
}

This same program showed the correct output when it was ran using the command prompt:

 gcc -g add.c -o add.exe

Have I made any mistake in the code? Can anyone suggest me what do I need to do to run it in Wclipse?

Answer 1

have you build the project in the first place? Go to "Project" tab in main tool bar and click on build project. If successful setup up a new run configuration for C under "Run" tab. And in the C/C++ application field -> "Search Project" and choose your project's binary from the list.

Now try running your custom run/debug configuration.
