7.2. string variablesΒΆ

You can create a variable with type string in the usual ways.

In the active code below, the first line creates a string without giving it a value. The second line assigns it the string value "Hello,". The third line is a combined declaration and assignment, also called an initialization.

Normally when string values like "Hello, " or "world." appear, they are treated as C strings. In this case, when we assign them to an string variable, they are converted automatically to string values.

We can output strings in the usual way:

cout << first << second << endl;

In order to compile this code, you will have to include the header file for the string class, and you will have to add the file string to the list of files you want to compile. The details of how to do this depend on your programming environment.

Run the active code below!
