What is the correct way to declare and initialize a one-dimensional array in C?

In C, you can declare and initialize a one-dimensional array as follows:

int arrayName[size];

Here, int is the data type of the array, arrayName is the name of the array, and size is the number of elements that the array can hold.

To initialize the array at the time of declaration, you can do:

int arrayName[] = {element1, element2, element3, ...};

Here, element1, element2, element3, ... are the values with which the array is initialized. The size of the array is determined by the number of values provided in the curly braces {}.

For example, an array of integers can be declared and initialized as follows:

int numbers[] = {10, 20, 30, 40, 50};

In this case, the array numbers has 5 elements. The first element numbers[0] is 10, the second element numbers[1] is 20, and so on.
