B5:C/C++ program to identify the available memory in the system.

Program:

#include<sys/sysinfo.h>

#include<unistd.h>

#include<stdio.h>

#include<iostream>

using namespace std;

int main()

{

structsysinfo a;

unsigned long tot;

sysinfo(&a);

cout<<"\n memory units "<<a.mem_unit<<"Units";

cout<<"\n total Ram "<<a.totalram;

tot=a.mem_unit*a.totalram;

cout<<"\n Total useable main memory units "<<tot;

            return 0;

}

Output:
