    You can detect ctrl+c by catching SIGTERM.

    Well that depends on your platform.
    Ctrl-C in windows typically copies things to the clipboard.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
    I support http://www.ukip.org/ as the first necessary step to a free Europe.

    Yeah, that took some time to get used to when I switched to UNIX... Same with ctrl+s freezing xterms instead of saving in vim.

    Code:
    #include <stdio.h>
    
    int
    main(void)
    {
            int c;
    
            c = getchar();
            if (c == '\a')
                printf("Caught ^G (0x07)\n");
    
            return 0;
    }
    Simple as that.

    That's ctrl+g not ctrl+c
    You'll need something more elaborate to catch signals (if indeed the OP is working on UNIX).

    which platform are you working on, Windows or Unix since the response to pressing Ctrl-C is dependent on that.

    He didn't say he wants to catch only ^C, he said he wants to catch it and others like that. I answered how to catch easily ones which don't have any special meaning provided by operating system, terminal or some other.
