C++: Converting Hexadecimal to Decimal

Question

I\'m looking for a way to convert hex^{(hexadecimal)} to dec^(decimal) easily. I found an easy way to do this like :

Answer 1

#include <iostream>
#include <iomanip>
#include <sstream>

int main()
{
    int x, y;
    std::stringstream stream;

    std::cin >> x;
    stream << x;
    stream >> std::hex >> y;
    std::cout << y;

    return 0;
}
