Write a C/C++ program to extract any fractional decimal number (for
example, 15, 15.0, 0.15 or .15) between the strings "Hello " and "
World!" (for example, "Hello 1.124 World!"), then return a float.
float ExtractFloat(const char *str)
{
....
}
Write a C/C++ function to allocate memory always aligned at a 16 byte
boundary.
int * AllocAlignedMemory(int numBytes)
{
....
}
Write a C/C++ program to reverse the bits in a 32-bit unsigned
integer.
unsigned int ReverseBits(unsigned int u)
{
....

1. There is no such language. There is C, and there is C++, but C/C++
does not exist.
2. Nobody here does other people's homework for them. Please do it
yourself. If you are stuck on a particular problem, feel free to ask
questions here, but please provide the code you're already trying and a
description of your specific difficulty.

I have vague memories of a language called C\C++ that somebody here
implemented, though. He might be thinking of that.

Sure we do. I just posted answers for somebody's binary tree homework;
I'm sure his teacher will definitely enjoy reading them, and maybe even
give him some pity marks.

Lookup table. 32 is only 24 more than 8.

Give us your instructor's e-mail address so I can submit the solution
directly. Don't worry, I'll be sure to mention your name.
Please provide a reference manual and implementation for this "C/C++"
language. I'm familiar with the C and C++ languages, but not with
"C/C++".
We'll discuss my consulting fees later; you can expect them to be
substantial.
Or you might consider not being a lazy slob and doing your own damned
homework rather than asking others to cheat for you. Just a thought.

What is "C/C++"?

Why should I? You don't even say please.
Did you have a question about C, or just some orders for us about "C/C+
+"? |

Not possible in portable C.
