How are strings represented in the C language?

In C language, strings can be represented in several ways:

1. Character array: It is possible to use a character array to store strings. For example, you can use char str[50] to define a string that can store up to 50 characters. Then, you can use the assignment operator = to assign a string to the character array, for example strcpy(str, “Hello World”).
2. Character pointer: Character pointers can be used to represent strings. For example, you can define a character pointer using char *str. Then, you can initialize the character pointer using a string constant, such as str = “Hello World”.
3. String constants: String constants are character sequences inside double quotation marks. For example, “Hello World” can be used to represent a string constant.

It is important to note that in the C language, strings are terminated with a null character ‘\0’. When representing strings using character arrays or pointers, it is necessary to ensure that the strings end with a null character. For example, one can use str[7] = ‘\0’ or str = “Hello\0” to add a null character to the end of a string.
