How to define variables in C language

The format for defining variables in C language is very simple, as follows:

数据类型  变量名;

Note: Do not lose the final semicolon. The definition of a variable is a statement, and statements end with a semicolon.

"Data type" indicates what type of variable you want to store. If you want to store integers, define it as int type; if you want to store decimals, define it as float or double type.

"Variable name" is what name you want to give this variable, usually using letters. For example:

int i;

The above statement indicates that an integer variable i is defined.
