not getting output
#include <stdio.h>

int sum (int, int);

main (void)
int total;

total = sum (2, 3);
printf ("Total is %d\n", total);

return 0;

sum (int a, int b)
return a + b;
there's no error in this program but still not seeing output just a blank screen flashes.....

Re: not getting output
Execute the program in IDE or put getchar() at the end of the program. The DOS screen(?!) is at the moment outputing the result and closing at the end. That is why you see the flash.
Best regards

Re: not getting output
Which IDE are you using? If you are using Visual studio then run it by pressing "CTRL + F5"
How are you trying to run the code?
use getchar() just before the "return 0" statement
