C program to get multiple line string

C program to get multiple line of string

Let us see how to read multiple line of string from console using gets function and two dimensional array.

how many lines required to be get it from user and gets user inputs for multiple lines and prints the list of lines provided by user.

num_of_lines variable is to have required number of lines.

lines two dimensional character array to have the multiple lines of string.
