Write a program that displays first n prime numbers.

#include<stdio.h>
#include<conio.h>
#include<math.h>

void main()
{
    long n,a[1000],prime,i,j,t,p;
    clrscr();
    printf("How many prime numbers : ");
    scanf("%ld",&n);
   
    p=0;
    for(i=2;p<n;i++)
    {
       prime=1;
       t=sqrt(i);
       for(j=2;j<=t;j++)
          if(i%j==0)
          {
             prime=0;
         break;
          }
       if(prime==1)
          a[p++]=i;
    }

    for(i=0;i<n;i++)
       printf("\n\na[%ld] = %ld",i+1,a[i]);
    getch();
}
