simple c program not printing output
22,638
The output is buffered for performance reasons. Replace
printf("The value is %d ", c);
with
printf("The value is %d\n", c);
or use fflush(stdout);
.
See Why does printf not flush after the call unless a newline is in the format string?

I have a simple c program
#include <stdio.h> int add(int, int); int add (int a, int b) { return a+b; } int main(void) { int a, b, c; printf("Enter the 1st number "); scanf("%d",&a); printf("Enter the 2nd number "); scanf("%d",&b); c = add(a, b); printf("The value is %d ", c); return (0); }
I am compiling the program with
cc main.c
and when I am running the program with./a.out
I am not getting any output in the console. -

kbau over 8 yearsI'm not sure why, but sometimes the newline character is not enough. I'm running mingw gcc (can't remember the exact version, but it might 4.9.2) and even with a newline character at the end of a string doesn't output it unless fflush(stdout) is called. P.S. who downvoted? It's a good answer, no?
