Name

= (assign)

Description

Assigns a value to a variable. The "=" sign does not mean "equals", but is used to place data within a variable. The "=" operator is formally called the assignment operator. There are many different types of variables (int, floats, strings, etc.) and the assignment operator can only assign values which are the same type as the variable it is assigning. For example, if the variable is of type int, the value must also be an int.

Examples

int a;
a = 30;  // Assigns for value 30 to the variable 'a'
a = a + 40;  // Assigns the value 70 to the variable 'a'

Syntax

var = value

Parameters

varany valid variable name
valueany value of the same type as the variable. For example, if the variable is of type "int", the value must also be an int
