Q: Write a Program for finding the prime numbers.


#include <stdio.h>
#include <conio.h>
void main()
{
  int n,m,k,i,max;
  char c;


repeat: 
  max=0;
  k=2;
  n=1;
  printf("You want prime numbers upto:  ");
  scanf("%d",&max);
  printf("\n");
  for (i=1;i<=max;i++)
{
again: m=(n/k)*k;
if (m!=n)
k=k+1;
else
goto try1;
if (k < n/2)
goto again;
else
printf("%d",n);
printf("  ");
try1: n=n+1;
k=2;
}
fflush(stdin);
 printf ("\n\nDo you want to continue?(y/n):-  ");
 scanf("%c",&c);
 if (c=='y')
  goto repeat;
getch();
}


Output:
