Question

The function takes a 4-digit integer as parameter, validates the integer and returns 1 when the digits are in increasing order or 2 when the digits are in decreasing order or 0 when the digits are not in any order

Answer 1

#include <iostream>




using namespace std;




int validateInteger(int number);


int main(){


	int value;
	cout << "Enter 4-digit integer value: ";
	cin>>value;
	if(validateInteger(value)==1){
		cout<<"The digits are in increasing order.\n";
	}else if(validateInteger(value)==2){
		cout<<"The digits are in decreasing order.\n";
	}else{
		cout<<"The digits are not in any order.\n";
	}




	system("pause");
	return 0;
}


int validateInteger(int number){
	int value=number;
	int digit = value % 10;
	value = value/10;
	int flagCounter=0;
	int numberOfDigits=0;
	while(value>0){
		if(digit > value % 10){
			flagCounter++;
		}
		digit = value % 10;
		value = value/10;
		numberOfDigits++;
	}
	if(flagCounter==numberOfDigits){
		return 1;
	}else{
		value=number;
		digit = value % 10;
		value = value/10;
		flagCounter=0;
		numberOfDigits=0;
		while(value>0){
			if(digit < value % 10){
				flagCounter++;
			}
			digit = value % 10;
			value = value/10;
			numberOfDigits++;
		}
		if(flagCounter==numberOfDigits){
			return 2;
		}
	}


	return 0;
}
