Summary
C programming does not provide direct support for error handling, but it does provide access to return values in the form of error codes. The C programming language provides two functions, perror() and strerror(), which can be used to display the text message associated with errno and to check if a divisor is zero before dividing. Additionally, it is important to exit with a value of EXIT_SUCCESS or EXIT_FAILURE depending on the error condition.

In C language, a function returns -1 or NULL value in case of any error and a global variable errno is set with the error code. So the return value can be used to check error while programming.
Whenever a function call is made in C language, a variable named errno is associated with it.
