What is the difference between pointers and arrays?

Can you explain the difference between pointers and arrays in C?

Sure! In C, an array is a collection of elements of the same type, while a pointer is a variable that stores the address of another variable.

So, can I say that an array is a type of pointer?

Not exactly. An array can decay into a pointer when passed to a function, but they are distinct types. An array has a fixed size, while a pointer can be reassigned.

What happens if I try to change the address of an array?

You can't change the address of an array itself, as it is fixed in memory. However, you can change the contents of the array.

Can you give me an example of how to use pointers with arrays?

Certainly! You can use a pointer to iterate through an array. For example:

int arr[] = {1, 2, 3};
int *ptr = arr;
for(int i = 0; i < 3; i++) {
    printf("%d ", *(ptr + i));
}
