C and C++ Programming Challenge Problems

Many of these problems will also make excellent preparation for programming job interview-style questions!

Basic Programming Challenges

Temperature Converter A small program to compute conversion tables from Celsius to Farenheit
Line Counting A relatively basic challenge that requires an understanding of file I/O
File Size Similar to line counting, but instead of computing the number of lines in a file, you compute the size of the file
Permutations The challenge is to find the algorithm used to create all possible permutations of a given string

Factorial Challenge No, not finding X factorial -- instead, the challenge is to write a program that can efficiently find the number of trailing zeros on X! for high values of X (say, 100).
String Searching Not only are you asked to determine if a given string is a substring of a second string, but you have to account for wildcards.
Decimal to Binary Program Write a program to convert a given decimal number to its binary equivalent.
Pascal's Triangle Tricks
Write a program to calculate the right value for a location in Pascal's Triangle.
Linked-list reverse print Write as clean a possible solution to the challenge of displaying a linked list in reverse
Linked-list in-place reversal Write code to reverse a linked list without using extra memory

Maximum Subarray Sum Find the fastest algorithm to compute the sum of the subarray with the maximum sum. It's possible to do it faster than you might think...
Self-Printing Program Write a program that can print its source code
