What is the meaning of *x = *x +1?

Question

#include <iostream>
using namespace std;

void printSomething(int * x) {
*x = *x + 1;
cout << *x << endl;
}

int main() {
int x = 42;
int* px = &x;
cout << x <<endl;
printSomething(px);
cout << x << endl;
}
Does it increment the location address by 1 ?for eg.if the location address of x is 02xff18 so after execution it will be 02xff19

Answer 1

No, it increments the value.

void printSomething(int * x) {
x += 1;
}
Would do this because *x means the value, x means the location.
