Do while loop help?

[ravee29]

Hello, do my program isn't working properly. It would just print a lot of *.

My program's main goal is to print a pattern.

ex:
Input = 5

*****

****

***

**

*

#include <stdio.h>
int x, b, c, d;
main()
{

printf("num:");
scanf("%d", &x);
	do
    {
          d=++x;
	do
	{
        b=++x;
       printf("*");
    } 
    while (x>b);
    printf("\n");
    printf("\n");
    	do
	{
        c=b++;
       printf("*");
    } 
    while (b>c);
}
while (x>c);

 getch();

}

I'm really confused with how my codes should look like...

You are getting in an infinite loop on lines 11 to 16.

[ravee29]

what do you mean by that?

Wouldn't x>b on line 16 break it?

In the process of b=++x there will come the time that b would be greater than x thus breaking the loop??

sorry, I'm still new here..

++x will increase x as well

#include <iostream>

int main()
{
int x=0, b;
for (int i=0;i<5;i++)
{
  b=++x;
  std::cout<<x<<b<<std::endl;
}
}

will produce

11
22
33
44
55

As you can see, b is always equal to x
