How to avoid pressing Enter with getchar() for reading a single character only?

Question

In the next code:

#include 

int main(void) {   
  int c;   
  while ((c=getchar())!= EOF)      
    putchar(c); 
  return 0;
}

Answer 1

This code worked for me. Attention : this is not part of the standard library, even if most compilers (I use GCC) supports it.

#include 
#include 
int main(int argc, char const *argv[]) {
    char a = getch();
    printf("You typed a char with an ASCII value of %d, printable as '%c'\n", a, a);
    return 0;
}

This code detects the first key press.
