Types of Variables

In the previous chapters, we printed some expressions. However, what to do if we need to store these expressions for future usage? In C++ (like in other programming languages) there are containers to keep data - variables. For each type of data (numbers, strings, characters) there is a type of variable.

Let’s take a look at the most often used types:

Why do we need to know the type of each variable? In Python, for example, you can store the data without worrying about its type.

When you declare variables in C++, the type of variable is a mandatory parameter, so knowing and correctly using data types will help to avoid many mistakes.

Let's look at an example of a variable declaration:


              12
            
int num = 42; 
cout << num;

You can also reassign your variable if it’s needed:


              1234
            
double num = 3.2;
cout << num;
num = 12.44;
cout << num;

You might also declare a variable but assign the value later or define the multiple variables of the same type in one declaration:
