Four basic data types in C #

This paper mainly introduces the knowledge of the four basic data types of C #, and has a good reference value. Let's take a look at the little series.

Character type char, which stores a character enclosed in "(single quotation marks), for example:

Char sex= ' male ';//Storage gender

A string that stores a string of characters enclosed in "" (double quotation marks), for example:

String address= "Niujie bei Kou, Xuanwu District, Peking City";//Storage address

Integer type int, which stores integers, for example:

int age=23;//Storage Age

Double-precision floating-point double, which stores decimals, for example:

Double salary=7991.63;//Store Payroll

The above four kinds are the most commonly used data types.

It is important to note that some type of variable can only store this type of data, otherwise, errors may occur.
