C Program to Swap Two Strings Using strcpy()

in this C program Swapping two strings involves exchanging the content of two character arrays. Here’s a simple program that demonstrates how to swap two strings.

Program :

#include<stdio.h>
#include<string.h>
#include<malloc.h>
#include<conio.h>
main()
{
char input1[100],input2[100],*temp;
printf(“Enter the first string : “);
gets(input1);
printf(“Enter sceond string : “);
gets(input2);
printf(“\nBefore Swapping\n”);
printf(“First Strings : %s\n”,input1);
printf(“Second Strings : %s\n\n”,input2);

temp =(char*)malloc(100);
strcpy(temp,input1);
strcpy(input1,input2);
strcpy(input2,temp);
printf(“After Swapping\n”);
printf(“First String : %s”,input1);
printf(“\nSecond String: %s”,input2);
getch();
return 0;

}

Output :
