How to define and assign values to character arrays in the C language?

In the C programming language, character arrays can be defined and assigned values as follows:

1. Character array is defined by specifying the data type as character and using square brackets [] to indicate the size of the character array.

char arrayName[size];

In this case, arrayName refers to the name of the character array, while size indicates the size or capacity of the character array.

1. Assign values to a character array: Values can be assigned to a character array using string constants or assigning characters one by one.

1. Assigning values using string constants:

char arrayName[] = "Hello";

1. By assigning characters one by one:

char arrayName[size];
arrayName[0] = 'H';
arrayName[1] = 'e';
arrayName[2] = 'l';
arrayName[3] = 'l';
arrayName[4] = 'o';
arrayName[5] = '\0'; // 在末尾添加字符串结束符

It’s important to consider the specific application scenarios and needs when assigning values to a character array.
