[FIXED] How to convert hex into dec string in C++?

Issue

I'm using C++11. Is there a function that gets the string of hex and turns it into decimal?

I've tried to find something about unicode() function that I saw somewhere in StackOverflow, but I couldn't find any information about it.

For example, we have a symbol hex: U+03C0. How to turn it into dec: 960?

Let's imagine this:

char* pi_symbol = hexToDec("U+03C0");
cout << "The pi dec is " << pi_symbol << endl;

And get this:

The pi dec is 960

Solution

You can use std::hex:

#include <iostream>
#include <sstream>
int main()
{
    int n;
    std::istringstream("03C0") >> std::hex >> n;
    std::cout << n;
}
