I have an assignment that I don't quite understand how to code because my teacher is a crackhead and tells us to learn from coding he's done 20 years ago.
I need to, given a hex string, write a function that returns its binary equivalent. We've only been through the basics of programming ie. apstrings, int stuff etc., so please keep it simple guys. I can't use the getline and .length commands.
He gave us these clues, which don't help me at all.
Code:
header:
apstring hex_binary
{
}
use concatenating binary characters
hex_binary
This is what I have so far
void numbers()
{ ofstream file1;
file1.open("a:numbers.dat");
if (!file1)
{cerr <<"\n file not open";
exit(1);
}
{ long first, second, third, largest, smallest;
cout<<"Key in first character.\n";
cin >>first;
cout<<"Key in second character.\n";
cin >>second;
cout<<"Key in third character.\n";
cin >>third;
Please keep it REALLY simple because I've only programmed in C for about a month. I can only use apstrings and int stuff. I searched the boards, but everything was so complicated.
Thnx in advance.
