Assigned a value that is never used (simple program)

Question

#include <stdio.h>
#include <conio.h>
int main ()
{
  int numc;
  puts ("NUMBER PLEASE");
  numc=getchar();
  printf ("%d");
  getch ();
  return 0;
}

I get the warning numc is assigned a value that is never used, while I'm trying to get the value. Please help.

I never really assigned a value to numc. I'm trying to get the value that the user types. – SirVirgin Apr 03 '15 at 13:34
numc=getchar(); this line actually assign the value which never used further in the program that is why it give warning.. – Deven Singh Apr 03 '15 at 13:40
so How do I get the number from the user by using getchar? – SirVirgin Apr 03 '15 at 13:44

Did you mean:

printf ("%d", numc);

? That would use the value the the compiler is warning you about.
