> could someone please explain to me how size_t works please?

size_t is a variable whose range of values covers all possible sizes
of other variables.  Example:

size_t a;
char b[100];
a = sizeof(b);  /* a is now 100 */
printf("a = %d\n", a); /* prints "a = 100" */

4 bytes.

You get a variable that can hold the value of the size of any object.
