What is the method for defining and declaring a string in the C language?

In the C language, strings can be defined and declared in several ways.

1. To use a character array: You can represent a string by defining a character array. For example:
2. Define an array of characters with a length of 10.
3. Using character pointers: Strings can be represented by defining a pointer that points to characters. For example:
4. Declare a pointer to a character named str.
5. One option to use string constants is to simply enclose the string within double quotation marks, representing the string. For example:
6. Initialize a character pointer using a string constant with the value “Hello”.
7. Initializing with character arrays: You can initialize a declared character array or character pointer using a character array. For example:
8. Initialize a character array with the string “Hello”.

It is important to note that in the C language, strings are actually made up of character arrays, with the character ‘\0’ serving as the end marker for the string. Therefore, before using a string, make sure the character array is large enough to accommodate the string and terminator.
