Write a function, reverseDigit, that takes an integer as a parameter and returns the number with its digits reversed. For example: the value of reverseDigit(12345) is 54321; the value of reverseDigit(5600) is 65; the value of reverseDigit(7008) is 8007; and the value of reverseDigit(–532) is –235

This program is written in C++. You can implement this program in any language. The code along with comments is given below in explanation section.

Explanation:

#include <iostream>  

using namespace std;  

int main()  // main function

{  

int number, reverseNumber=0, reminder;  //varible declaration  

cout<<"Enter a number: ";  //prompt user to enter the number  

cin>>number;   //save the entered number into number variable  

 while(number!=0)    //while number does not become zero remain in loop

 {    

    reminder=number%10;    // taken reminder of number    

    reverseNumber=reverseNumber*10+reminder;   //store the number digit into reverse order  

    number/=10; //decrease the number or shift the division to next digit    

 }    

cout<<"Reversed Number: "<<reverseNumber<<endl;    //print reversed number.  

return 0;  

}
