hello following is the source code for printing the number is prime or not if you want to only print prime number just delete last printf statement after else and also "is aprime number" from its previous printf statement. i am not able to see your source code now but yesterday see it and the is a "&" in printf statement in your while loop.

source code:
#include<stdio.h>
main()
{
int check, i, x,y,m;
printf("enter the number upto which check");
scanf("%d",&check);
y=1;
for(m=2; m<=check; m++)
{
for(x=2;x<m; x++)
{ y=m%x;
if(y==0)
break;
}
if(y!=0)
printf("%d is prime number\n",m);
else printf("%d is not a prime number\n",m);
}
getch();
}

i think u are bit confused with the name of variables u have taken,in the 2nd printf()[ after if()] u are trying to print m which has been already assigned a value of check.....so whenever the first if statment turns to be true a garbage value gets printed....
