Write a C++ program to swap two strings, where each strings are entered by the user.

Write a C++ program to swap two strings, where each strings are entered by the user.

Program Code:

#include<iostream>

#include<string.h>

#include<stdio.h>

using namespace std;

int main()

{

char str1[20], str2[20], temp[20];

int i=0, j=0, k=0;

cout<<"Enter the First String : ";

gets(str1);

cout<<endl;

cout<<"Enter the Second String : ";

gets(str2);

cout<<endl;

while(str1[i]!='\0')

{

temp[j]=str1[i];

i++;

j++;

}

temp[j]='\0';

i=0, j=0;

while(str2[i]!='\0')

{

str1[j]=str2[i];

i++;

j++;

}

str1[j]='\0';

i=0, j=0;

while(temp[i]!='\0')

{

str2[j]=temp[i];

i++;

j++;

}

str2[j]='\0';

cout<<"Strings after swapping are : ";

cout<<endl;

cout<<"First String = "<<str1;

cout<<endl;

cout<<"Second String = "<<str2;

return 0;

}

The program output is tested on www.jdoodle.com

Output:

Enter the First String : Suruchika

Enter the Second String : Mukesh

Strings after swapping are : 

First String = Mukesh

Second String = Suruchika

Thanks
