What are the methods for initializing character arrays in C language?

In the C language, character arrays can be initialized in various ways, including the following methods:

1. Initialize a character array using string constants.

char str[] = "Hello World";

1. Initialize a character array using character array initializer list.

char str[] = {'H', 'e', 'l', 'l', 'o', ' ', 'W', 'o', 'r', 'l', 'd', '\0'};

1. Initialize list using character array and initialize character array with specified size.

char str[12] = {'H', 'e', 'l', 'l', 'o', ' ', 'W', 'o', 'r', 'l', 'd', '\0'};

1. Initialize a character array using a loop structure.

char str[12];
for (int i = 0; i < 11; i++) {
    str[i] = 'A' + i;
}
str[11] = '\0';
