Exercises

1. A palindrome is a word or group of words that read the same forward and backward. For example “madam” or “wow”. Write a program that takes a string argument from the command line and returns TRUE if the string was a palindrome.
2. Sometimes the input from a file stream contains a two character sequence to represent a newline. These two characters (0x0a 0x0d) produce extra blank lines when the stream is printed to standard out. Write a program that finds the character 0x0d (ASCII carriage return) and deletes it from the string.
3. Write a program that reverses the order of the characters in a string.
