Write a program that does not terminate when Ctrl+C is pressed in C
In this problem, we have to create a program that does not terminate when ctrl+C is pressed. Instead, it prints
“Ctrl + C cannot terminate the program”.
For this, we can use signal handling. The signal SIGINT is created on pressing ctrl+c. To solve this problem, we will catch this signal and handle it.
Program to show the implementation of our solution,
Example
#include <stdio.h> #include <signal.h> void signalHandle(int sig_num) { signal(SIGINT, signalHandle); printf("
Ctrl + C cannot terminate the program
"); fflush(stdout); } int main (){ signal(SIGINT, signalHandle); while(!0) return 0; }
Output
Ctrl + C cannot terminate the program
