Program to sort a list in alphabatic order using pointers

 
#include <stdio.h>
#include <conio.h>
#include <math.h>
#include <alloc.h>
void main()
{

char *a[10],dum[10],s;
int i,k,j,n;
clrscr();
printf(\"enter the no of std....\");
scanf(\"%d\",&n);
printf(\"enter the name of students \");
for(k=0;k<n;k++)
scanf(\"%s\",a[k]);
for(i=1;i<n;i++)
{
for(j=1;j<n-i;j++)
{if(strcmp(a[j-1],a[j])>0)
  {strcpy(*dum,*a[j-1]);
   strcpy(*a[j-1],*a[j]);
   strcpy(*a[j],*dum);
 }
 }  }
 for(i=0;i<n;i++)
 printf(\"%s\",a[i]);
 getch();
 }
