Question

Write a program to reverse each integer number on array (size 3) using while loop. C++
Input: 3678 2390 1783
Output: 8763 0932 3871

Answer 1

#include <iostream>
#include <sstream> // for string streams
#include <string>

using namespace std;

int main()
{   long a[]={3678, 2390, 1783};
    long n, reversedNumber, remainder;
   for (int i=0;i<=2;i++)
   {   n=a[i];
       reversedNumber = 1;
       while(n > 0)
       {
        remainder = n%10;
        reversedNumber = reversedNumber*10 + remainder;
        n /= 10;
        }
      
    ostringstream str1; // declaring output string stream

    // Sending a number as a stream into output
    // string
    str1 << reversedNumber;

    // the str() coverts number into string
    string r = str1.str();
     cout << "Reversed Number = " << r.substr(1)<<endl;
    }

    return 0;
}

OUTPUT:

Reversed Number=8763

Reversed Number=0932

Reversed Number=3871
