BETTER CODE:
void main()
{
int i,n;
clrscr();
printf("Enter the number:");
scanf("%d",&n);
printf("\n\n The divisor's of %d are:",n);
for(i=1;i<=n/2;i++)
{
if(n%i==0)
printf(" %d ",i);
}
printf(" %d ",n);
getch();
}
This is better logic than the above program's.
For any number all factors will exit up to n/2 after n/2
only n is the factor.So, it is enough to execute the loop
for n/2 cycles . By this speed of execution increases.
EVEN BETTER LOGIC IS AVAILABLE 'U' TRY THIS...........
