1. your own bubble sort program
2. some multiplication tables with multi-deminsional arrays
3. a program to calculate the Fibinacci
4. code to take a year and tell if it's a leap year or not

Not very original, but great for learning some basic concepts.

Buying a book.
Take a peek at "accelerated C++". On short notice everything might be a challenge.

Take common libc functions and see if you can implement them on your own. (atoi, strlen, strcmp, strcpy)

Write a regular expression parser (no, don't. I'm kidding)

Create a program that can list out all prime numbers in a particular range as quickly as possible.

Ask the user to input a word, then generate a pattern from that word based on what letters were used in it - examples : "giggle" would come out as "121134" (hard to explain this one any better)

Implement ciphersaber/RC4 (easier to do than you would think)

Practice fileio, make a program that creates a carbon copy of a user-specified file.
