Hello
This program is not implemented?
If the
do-while(); Put, and the error is still not implemented.
Why is that?
Where is the problem?
Please help me.

#include<iostream.h>
#include<conio.h>
void main()
{
	int a,b;
	cout<<"please inter 1 integer : ";
    cin>>a;
    do
    {
    	b=a%10;
        a/=10;
        cout<<b;
    }
    while(a>9)
    {
    	b=a%10;
        a/=10;
        cout<<b;
    }
    if(a>0)
    {
    	cout<<a;
    }
    cout<<"\npress any key to exit.";
    getch();
}

This doesn't mean anything:

do
{
	b=a%10;
	a/=10;
	cout<<b;
}
while(a>9)
{
	b=a%10;
	a/=10;
	cout<<b;
}

You can either have

do
{
	b=a%10;
	a/=10;
	cout<<b;
}
while(a>9); // <- Note semicolon 

which checks the condition at the end (in other words, the loop runs at least once no matter what), OR

while(a>9) // <- Note no semicolon
{
	b=a%10;
	a/=10;
	cout<<b;
}

which checks the condition at the start (the loop may not run at all).
