Catching SIGINT signal to terminate a custom shell

Question

Hope you can help me to resolve this problem.

For school I have to transform Ctrl+C to a command which doesn\'t shut down the shell, but he reminds through

Ctrl+C sends an interrupt signal (SIGINT) to the running process.You can use signal() to catch SIGINT like this:

 #include
 #include

 void sigint_handler(int sig)
 {
   printf("Type exit to close the shell!\n");
 }


  int main()
  {
    signal(SIGINT, sigint_handler);

    /*Your code should replace the while loop.*/
    while(1)
    {
        printf("Running!\n");
        getchar();
    }

    return 0 ;
  }
