Question

C++

DESIGN and IMPLEMENT a PROGRAM THAT WILL CONVERT A DECIMAL NUMBER to its HEXIDECIMAL VALUE.

USE RECURSION TO ACCOMPLISH THIS.

OUTPUT: The Original Number and its HEXIDECIMAL EQUIVALENT.

Answer 1

#include <iostream>
#include <string>
using namespace std;

string decimal_to_hexadecimal(int number) {
    string s;
    int d;
    char ch;
    if (number > 0) {
        s = decimal_to_hexadecimal(number/16);
        d = number % 16;
        if (d < 10) {
            ch = (char)(d+'0');
        } else {
            ch = (char)('A'+(d-10));
        }
        s += ch;
    }
    return s;
}

int main() {
    int number;
    cout << "Enter a decimal number: ";
    cin >> number;
    cout << number << " in hexadecimal is " << decimal_to_hexadecimal(number) << endl;
    return 0;
}
