How to concatenate two strings in C++

In this tutorial, we are going to learn about how to concatenate the two strings in C++.

Concatenation means the joining of two strings into a single string.

To concatenate the two strings into a single string, we can use the + operator in C++.

Here is an example:

string a = "Welcome ";
string b = "John";
string c = a + b;
cout << c;

Output:

Welcome John

Similarly, we can use the built-in append() function in C++ to concatenate strings.

string a = "Welcome ";
string b = "John";
string c = a.append(b);

cout << c;

Output:

Welcome John
