Write a C program that doesn’t terminate when Ctrl+C is pressed. It prints a message “Cannot be terminated using Ctrl+c” and continues execution. We can use signal handling in C for this. When Ctrl+C is pressed, SIGINT signal is generated, we can catch this signal and run our defined signal handler.

Example C Program to Catch a Signal. Most of the Linux users use the key combination Ctr+C to terminate processes in Linux. Have you ever thought of what goes behind this. Well, whenever ctrl+c is pressed, a signal SIGINT is sent to the process. The default action of this signal is to terminate the process. But this signal can also be handled. If you set the action for a signal to SIG_IGN, or if you set it to SIG_DFL and the default action is to ignore that signal, then any pending signals of that type are discarded (even if they are blocked).
