here is the program pls help me figure out what is missing? thanks in advance..

#include <iostream.h>
#include<conio.h>
#include<string.h>


int ctr, sw=0, op, res;
char job[4], mm[10][4];

void main()
{ clrscr(); //intialize memory
for(ctr=0;ctr<10;ctr++)
strcpy(mm[ctr],"---");

while(op<4)
{
clrscr();
//display memory
for(ctr=0;ctr<10;ctr++)
{
gotoxy(5,ctr+4);
cout<<mm[ctr];
}
//options for memory management
gotoxy(1,15);
cout<<"OPTIONS";
gotoxy(1,17);
cout<<"1. ALLOCATION";
gotoxy(1,18);
cout<<"2. DEALLOCATION";
gotoxy(1,19);
cout<<"3. COMPACTION";
gotoxy(1,20);
cout<<"4. EXIT";
gotoxy(1,20);
cout<<"CHOICE:";
//enter choices[1-4] and place it to a variable op
gotoxy(10,22);
cin>>op;

switch(op)
{
case 1:
//initialize switch to 0 which signifies that memory is not yet full.
sw=0;
//test if the memory if already full
for (ctr=0; ctr<10;ctr++)
{ res=strcmp(mm[ctr],"---");
if(res==0)
{
gotoxy(1,24);
cout<<"ENTER JOB NAME :";
gotoxy(18,24);
cin>>job;
//how to input exlusivity here?
//exlusivity is the term use when two similar jobs are not allowed to be
//in the memory at the same time.
strcpy(mm[ctr],job);
// assign 1 as switch value after allocating the incoming job
sw=1;
break;

}

}
if(sw==0)
{
cout<<"MEMORY FULL!"
getch();
}
case 2: //how to input deallocation?
//is the process of freeing a memory location
break;

case 3:

//how to input compaction in c++
//compaction is the process of all occupied areas to
//one end or the other of the main storage.
break;

}
}

}

plsss. any idea c++ masters..??? thanks in advance.

conio.h is non-standard in c++...
