C Language: Constants

There are many rich data types in C, which are typically represented by constants or variables in development.

"Amount" represents data, constants represent commonly used data, they are fixed, cannot change data

Constant classification in C language:

int integer 4-byte: all integers included

Float Float 4 bytes: Includes decimal

Doule double-precision floating-point 8 bytes: Includes decimal

Char character 1 bytes: includes a symbol enclosed in single quotation marks, which makes up a character constant.

String constants: Enclose one or more characters in double quotation marks (""), which makes up a string constant.
