A variable refers to a storage location in the computer’s memory that one can set aside to save, retrieve, and manipulate data.
Declare a Variable
To create a variable, the type must be specified and a value must be assigned to it:
type name = value;
So to create a variable called
score of type
int and assign it the value 0:
int score = 0;
std::cout object is used together with the
<< operator to display variables.
To combine both text and a variable, separate them with the
int myAge = 30;std::cout << "I am " << myAge << " years old.";
The output would be:
I am 30 years old.
