Question

Write a function, reverseDigitthat takes an integer as a parameter and returns the number with itsdigitsreversed.

Forexample,thevalueofreverseDigit(12345)is54321;thevalueofreverseDigit(5600)is65;thevalueof reverseDigit(7008) is8007;andthe valueof reverseDigit(-532) is-235.

Answer 1

#include <iostream>


using namespace std;
int reverseDigit(int value)
{
    int res=0;
    while(value!=0)
    {
        res*=10;
        res+=value%10;
        value=value/10;
    }
    return res;
}


int main()
{
    cout << reverseDigit(12345) << "\n";
     cout << reverseDigit(5600) << "\n";
      cout << reverseDigit(7008) << "\n";
       cout << reverseDigit(-535) << "\n";
    return 0;
}
