pointer: points to variables place in memory. there are two parts to pointers. & - address-of operator : gets memory address * - Dereference operator : accesses the variable the pointer 'points' too int var = 5 ptr = &var // puts the memory address of var in ptr value = *ptr // puts the value pointed to by ptr into value.. (5) not the clearest. by i hope it helps 😊

You can also edit what the person is thinking *ptr = 6 would change var from 5 to 6
