Mell What are variables in computer games?
A variable is something that can be changed. In computer programming we use variables to store information that might change and can be used later in our program. For example, in a game a variable could be the current score of the player; we would add 1 to the variable whenever the player gained a point.
What is the use of variable in computer?

Variables are data values that can change when the user is asked a question, for example, their age. Variables may change during program execution. A variable is a memory location . It has a name that is associated with that location.
What data types are used in games?
There are many others Data Types, but these four (“int”, “float”, “string” and “bool”) are the ones we will use most often when we start to develop video games; later in next tutorials we will see how to declare other Data Types for variables and constants.
What is an example of a real life variable?
The picture and the list below show some real-life examples, where the value of a variable changes with the change in place and time. The temperature in different places also change. The height of a growing child changes with time. The speed of a car changes with time.
What is constant and variable in computer?
In computer programming, a constant is a value that should not be altered by the program during normal execution, i.e., the value is constant. This is contrasted with a variable, which is an identifier with a value that can be changed during normal execution, i.e., the value is variable.
