Small program ideas

Hello,

Some more ideas:

1. Implement sin(), cos(), tan() etc. The accuracy could be supplied as a
parameter to the program. The correctness can be checked very easily with
implemented versions.

2. Read a string/file and look for palindromes (the group of words that can
read from both ends: A toyota, Madam in Eden, I'm Adam...)

3. Read a string/file and draw that string on the screen in a whirlpool
way. Counter-clockwise sample of the string: "abigsnake":
sgi
nab
ake

4. Print first n Fibonacci numbers.

5. Calculate Pi value for the specified accuracy. From wiki: "...
irrational number, including π, can be represented by an infinite series of
nested fractions...". So it won't be very complicated to implement.

6. Implement dos2unix/unix2dos

7. Calculator, that gets a string, put data into a tree and after
calculates the value.
