I'm having some trouble with a program. I want the user to input a hex number as a char* pointer and then have that char* converted to a hex value.
Here is what I got so far
Code:
#include <iostream>
using namespace std;
int main()
{
char hex[256];
char *HexNum;
cout<<"Enter the Hex number to Convert";
cin.getline (hex, 256,'\n');
HexNum = hex ;
cout <<"the string is"<<hex<<endl;
cout <<*HexNum<<endl;
return 0;
}
oh and thanks in advance for any and all help.

You mean you want to enter something like
0x100
or
100
and turn this into an integer like say decimal 256?
If you want continue using char arrays in your C++ program, then
strtoul(3) - Linux man page
But you might want to consider all the possibilities that string streams and extractors have to offer.
