Study Notes
Fundamentals of Language and Variables
- The most fundamental part of any language is the variable.
Integer Variables and Memory
- On a 32-bit system, an int occupies 4 bytes (32 bits) of memory.
- The range of numbers an int can hold on a 32-bit system is -2,147,483,648 to 2,147,483,647.
Variable Types
- The general variable types used in most popular languages are integer, float, char, boolean, and string.
- The most commonly used type for integer variables is the int type.
Variable Location and Characteristics
- Variables are located in a computer's RAM (Random Access Memory).
- The fundamental characteristic of a variable is that it stores a value that can change.
- The amount of memory occupied by integer types is determined by the number of bits used to represent the type (e.g., 32 bits for an int on a 32-bit system).
