I am looking for a function to be able to review the total memory and the free memory from DevC ++, applicable in an object-oriented code and that can be used in a class for structures such as Listas and Arboles .
If the question is very long or has many answers, I would be very grateful if you would tell me a book or another place where I can consult such information.

You can use sysconf on Unix-like systems.
#include <unistd.h>
unsigned long long getTotalSystemMemory()
{
long pages = sysconf(_SC_PHYS_PAGES);
long page_size = sysconf(_SC_PAGE_SIZE);
return pages * page_size;
}
For windows-based systems GlobalMemoryStatusEx :
#include <windows.h>
unsigned long long getTotalSystemMemory()
{
MEMORYSTATUSEX status;
status.dwLength = sizeof(status);
GlobalMemoryStatusEx(&status);
return status.ullTotalPhys;
}
