Variables are used to store values. Variables are so central to programming that you'll almost never come across which doesn't use variables.
A good analogy for the variable is a box. You can imagine the name of the variable as the label on the box, and the value of the variable as what's stored inside it.
Let's create a new string variable called name:
string name = "Commonlounge";
The above is equivalent to saying: Store the value "Commonlounge" in variable name.
So how do we know that the variable actually exists? Simply display the variable with cout command:
type=codeblock|id=cpp_string_variablecout << name << endl;// Output - Commonlounge
Yippee! Your first variable! :)
