Indexed File Allocation method

Write a C Program to implement Indexed File Allocation method
#include<stdio.h>
#include<conio.h>
#include<stdlib.h>
void main()
{
int f[50], index[50],i, n, st, len, j, c, k, ind,count=0;
clrscr();
for(i=0;i<50;i++)
f[i]=0;
x:printf("Enter the index block: ");
scanf("%d",&ind);
if(f[ind]!=1)
{
 printf("Enter no of blocks needed and no of files for the index %d on the disk : \n",
ind);
 scanf("%d",&n);
}
else
{
 printf("%d index is already allocated \n",ind);
 goto x;
}
y: count=0;
for(i=0;i<n;i++)
{
 scanf("%d", &index[i]);
 if(f[index[i]]==0)
 count++;
}
if(count==n)
{
 for(j=0;j<n;j++)
 f[index[j]]=1;
 printf("Allocated\n");
 printf("File Indexed\n");
 for(k=0;k<n;k++)
 printf("%d-------->%d : %d\n",ind,index[k],f[index[k]]);
}
else
{
printf("File in the index is already allocated \n");
printf("Enter another file indexed");
goto y;
}
printf("Do you want to enter more file(Yes - 1/No - 0)");
scanf("%d", &c);
if(c==1)
 goto x;
else
 exit(0);
getch();
}

Output:
