2. Write a program that reads from a file called story.dat(Doc Folders\Mackinnon\ICS 3M\String), replaces all occurrences of he with he/she, and outputs to a file called story.out. Save as str1.t (4 marks)

3. Write a function called rep that takes a string, and returns a string. The initial string will have a number at the beginning. The result will be the rest of the string repeated a number of times equal to the initial number. Save as str1.t (4 marks)

Output

e.g. put rep("4you") youyouyouyou

4. Write a program that eliminates all spaces from a file. Your program will ask for the file, open it then output to the screen. Save as str1.t (4 marks)

5. Write a function called mirror that takes a string and returns a string. The result will be the original string plus the string in reverse. Save as str1.t (5 marks)

mirror("is") issi

6. Write a procedure called elim that takes a string and a letter. The first string will change. In place of all occurrences of the letter place an *. Save as str1.t (5 marks)

A palindrome is a word that is spelled the same foward as it is backward. You are to ignore all spacing, punctuation and case in your comparison. Save as str1.t (5 marks)

Result

e.g. palindrome(“Racecar”) true

palindrome(“Madam I’m Adam”) true

palindrome(“dog”) false
