Character array refers to an array used to store character data. The general form of its definition is: char array name [data length]. Character array is used to store characters or strings, and one element in the character array stores one character, occupying one byte of memory. C language has no string type, and strings are stored in character arrays.

An array used to store character data is called a character array. An element in a character array holds a character. The method of defining a character array is similar to that of defining a numeric array.

The general form of its definition is: char array name [data length]

For example:

char c[ 10]；

c[0]= ' I '； c[ 1]=“”； c[2]= ' l '； c[3]= ' o '； c[4]= ' v '； c[5]= ' e '； c[6]=“”； c[7]= ' y '； c[8]= ' o '； c[9]= ' u '；

C is defined as a character array containing 10 elements.

Because character data is stored in the form of integers (ASCII codes), you can also use integer arrays to store character data, for example:

int c[ 10]；

But at this time, each array element occupies 2 bytes of storage unit, wasting storage space. [ 1]?

Character arrays can also be two-dimensional or multi-dimensional arrays, for example:

char c[5][ 10]；

This is a two-dimensional character array.
