//This code displays prime factors only

#include<stdio.h>
#include<conio.h>
void main()
{
int i,j,n,x,flag=0,d,count=0;
clrscr();
printf("\tPRIME CHECK\n");
printf("Enter a no:");
scanf("%d",&n);

for(j=2;j<n,n%j!=0;j++)
if(n-1==j)
{
printf("\n\t%d is a prime",n);

flag=1;
}

if(!flag)
{
printf("\nNumber %d is not a prime",n);
printf("\nIts factors are:\n\t");

x=2;
while(n!=1)
{
