Description

• The Search for a Character

Since you are reading this, you have already downloaded and extracted the zip file.

1.1 Tasks to do

1. Take a look at the starter file. As you can see, a call is being made to the index function.

This function should take in a character pointer (which is the starting location of a string). It should also take in a character as a parameter. The function should search for this character within that string.

1. 1. If the character is found, it should return the index of that character (0-based)

1. 2. If the character is not found, it should return -1

1. 3. If the character is found more than once, it should return the index of the first occurrence

2. The second function you need to write is count_digits. This should again take in a character pointer (which is the starting location of a string) and count the number of digits in that string. Note that in ASCII, digits go from 48 to 57.

3. A strict requirement is that you cannot use the index operator – [] – to access the characters of the string in either of the functions. You must use a pointer and move that pointer to different characters within the string to perform search and count.

4. After you’re done making your code work, write down (read: assignment must be hand-written) the full declaration and definition of both the functions on a paper and submit that on or before the deadline. Late assignments (or soft copies) will not be accepted.
