HELP ... hex to decimal conversion

[neborah]

//hex to decimal and bianary
	char hex;

	const string myHexString = hex;
	
	char *line = "short line for testing";
	long strtol( const char *nptr, char **endptr, int base );
	cout<<strtol(myHexString,NULL,16);
	//int x = (int)c2;
	cout << "int HEX: " << dec << x << endl;
	system ("pause");
	return 0;

this is my fricken code ... ive been working on this program for 2 weeks and this is the only problemn other then this the whole program works

I'm guessing that the strtol() is giving you problem. Try this:

cout << strtol( myHexString.data(), NULL, 16 );

This would be better as

cout << strtol( myHexString.c_str(), NULL, 16 );

while both data() and c_str() return a const char*, only the latter is required to ensure it's a pointer to a null terminated string.

what problem?

Are you not over complicating it or am i missing the point?
1) enter a number in hex format
cin>>n;//n is entered as b00b
2)cout<<dec<<n<<endl;//prints 45067
....so why enter the hex numeral as a string is what i'm asking?
