CS12, Lab 8

Week of February 25 – March 1

Topics

· Character strings

· Pointers

· The string.h library

· Recursion

In this lab you will use three different methods to compare two character strings.

To do

Write a program that will prompt the user for two strings and check if they are equal using three different methods:

1. Using the strcmp function in string.h

2. Calling a function (that you write) that loops through the two strings comparing character by character.

3. Calling a recursive function (that you write) that takes two pointers to char as parameters and does the following:

a. If the pointers point to different characters, return false

b. If both pointers point to the null character, return true

c. If both pointers point to the same (non-null) character, advance both pointers and call the recursive function again, returning the result of the recursive call.
