You are required to make changes in the below programs and introduce the use of compaction where required.

 

#include<stdio.h>

#include<conio.h> #define max 25

void main()

{

int frag[max],b[max],f[max],i,j,nb,nf,temp,lowest=10000; static int bf[max],ff[max];

clrscr();

printf("\nEnter the number of blocks:"); scanf("%d",&nb);

printf("Enter the number of files:"); scanf("%d",&nf);

printf("\nEnter the size of the blocks:-\n");for(i=1;i<=nb;i++)

printf("Block %d:",i);scanf("%d",&b[i]);

printf("Enter the size of the files :-\n");for(i=1;i<=nf;i++)

{

printf("File %d:",i); scanf("%d",&f[i]);

}

for(i=1;i<=nf;i++)

{

for(j=1;j<=nb;j++)

{

if(bf[j]!=1)

{

temp=b[j]-f[i];if(temp>=0)

if(lowest>temp)

{

ff[i]=j;

lowest=temp;

}

}

}

frag[i]=lowest;

bf[ff[i]]=1;

lowest=10000;

}

printf("\nFile No\tFile Size \tBlock No\tBlock Size\tFragment"); for(i=1;i<=nf && ff[i]!=0;i++)

printf("\n%d\t\t%d\t\t%d\t\t%d\t\t%d",i,f[i],ff[i],b[ff[i]],frag[i]);

getch();
