#include<stdlib.h>
int main()
{
int i=0,j=0;
char m2[30],m3[100];
char m1[40]="Programming is great fun!";//Declares a C-String called ‘m1’ and
initializes it with text “Programming is great fun!”
puts(m1); //Uses C-function puts() to print this string.
printf("Enter a string name : \n");
gets(m2);//Asks the user to enter a String named ‘m2’ (Hint: Use gets()
function for this.)
//Concatenates the two strings and stores the result in ‘m3’.

CRITICAL ANALYSIS:
In this lab we have learned the basic operations with Strings, differentiate
between C Strings and 2D arrays, using built-in C functions for string
manipulation and develop custom functions for C String manipulation.
