How can strings be represented in the C language?

In C language, strings can be represented using character arrays. In particular, character arrays can be used to store each character of a string, with ‘\0’ serving as the string’s terminating character. Here are some common methods for representing strings:

1. Using a character array literal:

char str[] = "Hello, World!";

1. Use an array of characters.

char str[15]; // 声明一个字符数组，大小为15，用于存储字符串
strcpy(str, "Hello, World!"); // 将字符串拷贝到字符数组中

1. Utilize character pointers:

char *str = "Hello, World!"; // 声明一个字符指针，指向字符串常量

It is important to note that when using a character pointer to represent a string, the content of a character array or string constant cannot be modified because they are usually stored in read-only memory. If there is a need to modify a string, a character array should be used instead, along with the appropriate string manipulation functions.
