A man of Love and Hate char (character type)

Today to summarize the char type, the usual writing algorithm for this thing feel a bit around, in the final analysis or this part of the knowledge is not familiar with so a little afraid of him, but do not be afraid, today to summarize

First, when it comes to character data types, char type, well, it's a data type.

Then, it's the character variable .

The emphasis of a character variable is to store a character in a character variable, not the shape of the character, but the ASCII code of the character.

Input: GetChar ();

Output: Putchar ();

The difference between GetChar and scanf is that he can enter spaces

Character-type constants:

1. General

A

2. Escaping

1. ' \ t '

Slash + character

2. ' \ ' + character Anscii code,

\DDD octal corresponding characters

String constants:

"ABDF"

The difference between ' a ' and ' a '

Note:: There are no string variables, only string constants exist

Storing a string requires a character array

Character array:

Char A[5]

1. Initialization of character arrays

1. Class with character constants

Char a[8]={' C ', ' h ', ' I ', ' n ', ' a '}

If not initialized, the values of the elements of the array are random

2. If partially initialized, the following automatic null character

2. Class with a string constant.

Char a[8]={"China"};

Char a[8]= "China";

' !!!! The assignment operation must never use a string constant, but can be used to assign a value to a character constant

Char a[100];

A[100]= "ABC" is wrong.
