Pointers in C in a nutshell!
Pointers are used for dynamic memory allocation in C, the quick overview:
int number = 54; //Assigns variable called number the value 54
int *pointme = 52; //Creates a pointer variable named pointme and assigns it a value of 52
int *pointme = &number; //Points pointme variable to the address in memory of the variable number
printf("Pointer address %p has a value %d", pointme, *pointme); //Print out the address and value of the pointer
