{
int n,num,t,div,count;
printf("How many prime number you want to print: ");
scanf("%d", &n);
printf("\n%d\t",2); /*2 is first prime number*/
count=1;
num=3;
while(count<n)
{
t=sqrt(num);
div=2;
while(div<=t)
{
if(num%div==0)
break;
div++;
}
if(div>t)
{
printf("%d\t",num);
count++;
}
num=num+2;
}
getch();
return 0;
