An int is a single whole number within C#.

Think of computer memory as a series of boxes. Inside each box can store something with a given ‘type’. When using an ‘int’, we are telling the computer to store a whole number.

Here is an example:

int fred = 23;

By writing ‘int’ we have written that we want that box in memory that contains a whole number (an int) and ‘fred’ is a name or variable for that ‘box’ in memory

Then comes the =, this says we have a box that contains a whole number named fred and the number we want in that box is equal to the number 23. Then the ; to end the line.

To print this onto the console you need to use the following code

Console.WriteLine(fred);
