What is the method to initialize a C language character array to be empty?

In C language, character arrays can be initialized as empty in the following ways:

1. Initializing arrays with an empty initialization list allows you to set the array to all zeros (empty characters) when defining it.

char array[100] = {};

1. Initialize using a loop: you can assign each element of the array to an empty character using a loop statement.

char array[100];
for(int i = 0; i < 100; i++) {
    array[i] = '\0';
}

1. You can utilize the memset function to set all elements in an array to a specific value, such as initializing the array to empty characters.

char array[100];
memset(array, '\0', sizeof(array));
