Read Hexidecimal
-
Are there any standard functions, either in the c libary or in windows, that can be used to read a hexidecimal number from a string similar to atoi?

#include <iostream>
#include <cstdio>using namespace std;
int main()
{
string str = "0x1F";
int hex = 0;
sscanf(str.c_str(), "%X", &hex);
cout << "Hex value: " << hex << endl;
return 0;

I saw this before, but for some reason it did not seem that it worked that way to me. Thanks
