Fatalfloor...

There are a couple of ways to do this... first, you can use memcpy() to copy the exact representation into the char array.

You can use bit shifting and bit masking techniques as well. I'm guessing this is what you need to do as it sounds like a homework problem.

Lastly, you can use some fancy pointer indirection to copy the memory location you need.

All of these methods are detailed here:
