OS Memory Variable Partioning Type C Program

Program Name	write a OS Memory Variable Partioning Type C Program
Theory	In Memory Variable Partioning we give a variable memory for each process.
Program	#include<stdio.h> #include<conio.h> void main() { int memorysize,mp[10],i, temp,n=0; char ch = 'y'; printf("\nEnter Total memory available (in Bytes)"); scanf("%d",&memorysize); temp=memorysize; for(i=0;ch=='y';i++,n++) { printf("\nEnter memory required for process %d (in Bytes)",i+1); scanf("%d",&mp[i]); if(mp[i]<=temp) { printf("\nMemory allocated for Process: %d ",i+1); temp = temp - mp[i]; } else { printf("\nMemory is Full"); break; } printf("\nDo you want to continue(y/n) -- "); scanf(" %c", &ch); } printf("\n\nTotal Memory Available: %d", memorysize); printf("\n\n\tProcess \t\t Memory Alloted "); for(i=0;i<n;i++) printf("\n \t%d\t\t%d",i+1,mp[i]); printf("\n\nTotal Memory Allocated : %d",memorysize-temp); printf("\nTotal External Fragmentation : %d",temp); getch(); }
Input	Enter Total memory available (in Bytes)1000 Enter memory required for process 1 (in Bytes)399 Memory allocated for Process: 1 Do you want to continue(y/n) -- y Enter memory required for process 2 (in Bytes)276 Memory allocated for Process: 2 Do you want to continue(y/n) -- y Enter memory required for process 3 (in Bytes)551
Output	Memory is Full Total Memory Available: 1000 Process Memory Alloted 1 399 2 276 Total Memory Allocated : 675 Total External Fragmentation : 325
