SIMULATE PAGING TECHNIQUE OF MEMORY MANAGEMENT

Simulation of Paging technique of Memory Management:-

#include<stdio.h>
#include<conio.h>
#include<math.h>
main()
{
int size,m,n,pgno,pagetable[3]={5,6,7},i,j,frameno;
double m1;
int ra=0,ofs;
clrscr();
printf("Enter process size (in KB of max 12KB):");/*reading memeory size*/
scanf("%d",&size);
m1=size/4;
n=ceil(m1);
printf("Total No. of pages: %d",n);
printf("\nEnter relative address (in hexadecimal notation eg.0XRA) \n");
//printf("The length of relative Address is : 16 bits \n\n The size of offset is :12 bits\n");
scanf("%d",&ra);
pgno=ra/1000; /*calculating physical address*/
ofs=ra%1000;
printf("page no=%d\n",pgno);
printf("page table");
for(i=0;i<n;i++)
printf("\n %d [%d]",i,pagetable[i]);
frameno=pagetable[pgno];
printf("\n Equivalent physical address : %d%d",frameno,ofs);
getch();
}

output:-
