Concatenate two strings c++: In the previous article, we have discussed C++ Program to Find the Length of a String. In this article, we will see C++ Program to Concatenate Two Strings.
C++ Program to Concatenate Two Strings

C++ program to concatenate two strings

#include <iostream>
#include <cstring>
using namespace std;
int main(){
char first[1000], second[1000];
int i = 0, len;
cout << "Enter first string"<< endl;
cin.getline(first, 1000);
cout << "Enter second string"<< endl;
cin.getline(second, 1000);
len = strlen(first);
while(second[i] != '\0'){
first[len] = second[i];
len++;
i++;
}
first[len] = '\0';
cout << "Concatenated String"<< endl<< first;
return 0;
}
Output
Enter first string Btech Enter second string Btechgeeks Concatenated String BTechGeeks
