Hello, I made a program to test cheat engine with it, however I tried to use the address given by std::cout but cant use that and cant search for value either.
I would like to have a hint why its not working, thanks
Code:
#include <iostream>

int main()
{
   unsigned int counter = 1;
   unsigned int* ptr;
   while (true) {
      counter = counter + 1;
      std::cout << "counter: " << counter << std::endl << "mem: " << (void*)&counter << std::endl << "size: " << sizeof(counter) << std::endl;
      ptr = &counter;
      std::cout << "ptr: " << *ptr << std::endl << "mem: " << ptr << std::endl;
      std::cin.get();
   }
   return 0;
}
[/code]

The compiler optimized away all memory accesses to `counter`

Use volatile
Code:
volatile unsigned int counter = 1;

Changed the code

Code:

#include <stdio.h>


int main()
{
   volatile unsigned int counter = 1;
   while (counter < 100) {
      counter = counter + 1;
      printf("counter: %d, mem: %016llX", counter, &counter);
      getchar();

   }
   return 0;
}


and in the disassembly there is access to memory but still nothing on CE

Are you attached to the correct process? i.e. don't attach to the console- attach to the program the console is running
