Find String Length using Predefined Function in C

This program is used to find the length of a given string. It uses the strlen function from the string.h library to determine the length of the string. The program takes the input string from the user and stores it in the character array a. Then, it calls the strlen function and passes the a array as an argument. The function returns the length of the string and the program prints it on the screen.
