C Exercises: Set a function that will be executed on termination of a program
C Variable Type : Exercise-15 with Solution
Write a C program to set a function that will be executed on termination of a program.
Sample Solution:
C Code:
#include<stdio.h> // Include the standard input/output header file.
#include<stdlib.h> // Include the standard library header file.
// Function to be executed when the program exits.
void newFunctionOne (void)
{
puts (" Here is the message returning from newFunctionOne.");
}
// Another function to be executed when the program exits.
void newFunctionTwo (void)
{
puts (" Here is the message returning from newFunctionTwo.");
}
int main () // Start of the main function.
{
atexit (newFunctionOne); // Register 'newFunctionOne' to be executed at program exit.
atexit (newFunctionTwo); // Register 'newFunctionTwo' to be executed at program exit.
puts ("\n This is the message from main function."); // Print a message from the main function.
return 0; // Return 0 to indicate successful execution of the program.
} // End of the main function.
Sample Output:
This is the message from main function. Here is the message returning from newFunctionTwo. Here is the message returning from newFunctionOne
