What is concatenation between strings in C++ with code example

Concatenation between strings in C++

Concatenation combines two or more strings together. Here is a code to understand its concept:

#include <iostream>

#include <string>

using namespace std;

void main() {

      string a("abcd efg");

      string b = "xyz ijk";

      string c = a + b; // concatenation

      cout << "First character of " << c << endl; // as in C

      system("pause");

}
