Smart Code For YOU

Write a C++ program to concatenate one string contents to another.

Here, to concat two string we attach second string at the end of first string and for that we need to find the length of first string.

Program Code:

#include<iostream>

using namespace std;

int main( )

{

int i, j, length = 0;      //This variable is to hold length of first string

char name1[30], name2[30];

cout<<"Enter your first string: ";

cin.getline(name1, 30);

cout<<endl;

cout<<"Enter your second string: ";

cin.getline(name2, 30);

cout<<endl;

for(i = 0; name1[i] != '\0'; i++) //This loop is to find length of first string.

{

length = length + 1; 

}

for(j = 0; name2[j] != '\0'; j++) //This loop is to add second string in first string

{

name1[length++] = name2[j];

}

name1[length] = '\0';

cout << "\n Concatenation of first & second string : " ;

cout<< name1;

return 0;

}

The output of this program is tested on www.jdoodle.com

Output:

Enter your first string: Mukesh Kumar

Enter your second string: Suruchika

Concatenation of first & second string: Mukesh KumarSuruchika
