Write a function that takes an integer value and returns the number with its digits reversed?

Answer 1

// reversed.cpp

#include

using std::cout;

using std::cin;

using std::endl;

using std::ios;

#include

using namespace std;

int reversByValue(int);

int main()

{

int num;

cout << "Enter a number (0 for End): "

cin >> num;

while (num != 0) {

cout << "The number with its digits reversed is: "

<< reversByValue(num) << endl;

cout << "\nEnter a number (0 for End): ";

cin >> num;

}

cin.ignore();

return 0;

}

int reversByValue(int numRev)

{

int resultNum = 0;

while (numRev != 0)

{

resultNum = (resultNum * 10) + (numRev - (numRev / 10) * 10);

numRev = numRev / 10;

}

return resultNum;

}
