void printAge(int *pAge)
{
printf("You are %d years old
", *pAge); //dereference

int main()
{
// pointer = a "variable-like" reference that holds a memory address to another variable, array, etc.
// some tasks are performed more easily with pointers
// * = indirection operator (value at address)
int age = 21;
int *pAge = &age;
printAge(pAge);
//printf("address of age: %p
", &age);
//printf("value of pAge: %p
", pAge);
//printf("size of age: %d bytes
", sizeof(age));
//printf("size of pAge: %d bytes
", sizeof(pAge));
//printf("value of age: %d
", age);
//printf("value at stored address: %d
