A pointer is an integer that stores the memory address.
Consider a single street, with houses on one side from start to end.
Memory in a computer is just like this street, its an one dimmensional array/line, with a sequence of byte arranged in that 1D array. So one byte is equivallent to one house.
Now each house will have an address. If someone want to post a gift to a particular house you need an address to that house. Similarly for writting / reading from memory you need the address to that particular byte. This address is held by the pointer.
