e.g: if the number = 1234 then the output will be 4321.

What have you tried? Where are you stuck? How can we help you without seeing what you have tried?

you must try Something

well first receive the input as a string but i think that's standard(could be wrong here)
a string is an array of chars, now think about what you can do with array's,
array[indexnumber] gets you a value.
now think about the position of a digit in that string array and think about what you could do with that

Forget about C++ code for a minute and think about the problem. Write down on paper how you could solve this step by step. When you have figured that out, converting your steps into code will be a breeze.

Have a crack with brute force and ignorance then others on here can show you some tricks that'll show you how to solve it using some language tricks.

Solution 2

Try With this:

C++

int main ()
{
	bool intEntered = false;
	char input[255] ;
	int number;

	do{
	cout<<"Input numbet: ";
	cin >> input;
	string s = input;
	number = atoi(s.c_str());
	if ( number == 0 )
	cout << "Null is not alowed :) ";
	else
		intEntered = true;

	}while(!intEntered);
}

Then use for loop to read from last digit. Voila!!!!

There's enough rubbish C++ in the world - please don't add to it, even if you're being ironic.
