C++ Program to Concat Two Strings

Write C++ Program to Concat Two Strings

// CPP Program to Concat Two Strings

#include <iostream>
#include <string.h>

using namespace std;

int main()
{
	char S1[] = "Code", S2[] = "Crucks";
	char S3[20];
	int i = 0,j = 0;

/*
    strcat(S1,S2);			// Using inbuilt function
    cout << "Concatination string is " << S1);
*/

    // Doing manually
	while(S1[i] != '\0')
	{
		S3[j] = S1[i];
		i++;
		j++;
	}

	i=0;
	while(S2[i] != '\0')
	{
		S3[j] = S2[i];
		i++;
		j++;
	}

	S3[j] = '\0';
	cout << "String S1 :--> " << S1;
	cout << "\nString S2 :--> " << S2;
	cout << "\n\nConcatenated String :--> " << S3;

	return 0;
}

Output:

String S1 :--> Code
String S2 :--> Crucks

Concatenated String :--> CodeCrucks
