A pointer is a variable that points to a location in memory. Here is an example below:

#include <iostream>//For those unaware, the lib "iostream" stands for input output stream and is used mostly for stuff like cout or cin.
//int main() is the main function which will run upon running the exe file.
int main() {
	int x = 10;//The variable we are looking to point too
	int* xptr = &x;//using "&" you get the momory location of the variable x and you are telling xptr to point to x's location.
	std::cout<<xptr<<std::endl;//prints to location it's pointing too
	std::cout<<&x<<std::endl;//If you did it correctly it will output the same thing as xptr
	std::cout<<*xptr<<std::endl;//It will print the value(10) of the variable its pointing too. this is called derefrencing
	std::cout<<x;//It will print 10.
	return 0;
}

/*
Here is how pointers work in a nustshell(represent | as what's
happening in the memory and / as a place in the ram):
int x = 2; | 2/0x00ef5
int *z = &x| 0x00ef5/0x00ef6 (See how the value of the pointer z
matches with the memory address of x? that's how they work!)

when you print out the pointer as *n (replace n with the var name)
it will actually look at the value
see it's a memory address
go to that memory address
and print the value originally in the memory address which is 2

Here is code:
*/
int x = 5;
int *y = &x;
cout << *y+1;
/*
the reason why i did *y+1 was so to show that after it got
the value from the memory address it will add 1
*/
