Try to use '\r' instead. The 'Enter' key represent Carriage Return that is the same as '\r'.

This program reads from standard input and writes "enter pressed" whenever a newline occurs in the input:

#include <stdio.h>

int main()
{
    int c;

    for (;;) {
        c = getc(stdin);
        switch (c) {
        case '\n':
            printf("enter pressed\n");
            break;
        case EOF:
            return 0;
        }
    }
}

I think this is what you are looking for.

You might be missing the trailing \n in your printf-call, causing the message to be buffered for output but maybe not flushed so it appears on the screen.

"Enter" represents a new line character in C language. So you can use its ascii value i.e. 10 for its representation. Eg : 

#include<stdio.h>

Try this code : 

int main()
{
   char ch = '\n';
   printf("ch = %d\n", ch);
}

Later you can use the following code as a test for switching '/n'

int main()
{
  char ch = '\n';
  switch(ch)
  {
    case '\n' : 
           printf("Enter pressed\n");
    break;
    default : 
       //code
  }
}
