hey guys anyone can explain the operation part of code clearly? I have an exam and i need to learn this asap

#include <iostream>
using namespace std;

> int main()
> {
>     int m = 44;
>     int* p = &m;
>     int& r = m;
>     int n = (*p++);
>     int* q = p - 1;  // Corrected the subtraction operator
>     r = *(--p) + 1;
>     ++*q;
> 
>     cout << "m is " << m << endl;
>     cout << "n is " << n << endl;
>     cout << "&m is " << &m << endl;
>     cout << "*p is " << *p << endl;
>     cout << "r is " << r << endl;
>     cout << "*q is " << *q << endl;
> 
>     return 0;
> }

It might help if you give us more specifics on what exactly you don’t understand.
