Compile and run the following two programs: 1.c and 1_NULL.c

Why does the second program crash?

fix the problem in the 1_NULL.c program by modifying the 1 function such that whenever NULL value is used as its first argument during the function call from main function, this function displays a meaningful error message and the program

exits normally.

Tip:

To exit a program, you may use the exit() function. It takes an integer (zero or non-zero) to represent

different exit status. You must include the header file.

- Exit Success is indicated by exit(0) statement which means successful termination of the

program, i.e., program has been executed without any error or interrupt.

- Exit Failure is indicated by exit(1) which means the abnormal termination of the program, i.e.,

some error or interrupt has occurred. We can use different integer other than 1 to indicate

different types of errors. For this program, you may use the exit(1); statement. Because you want to terminate the program due to null pointer error. Make sure that the NULL argument is used as instructed above.
