You are given a main function, and must implement the function called char uppercase(char c). Copy the program uppercase.c from the course account to your directory by typing (make sure you type the dot at the end):

The char uppercase(char c) function takes in a character, c and if it is an lowercase letter, converts it to uppercase and returns that value. All other input values are returned unchanged.

Some Examples

abc
ABC

ABCabc123
ABCABC123

123!@#
123!@#

To run some simple automated tests:

$ 1511 autotest uppercase

To run Styl-o-matic:

$ 1511 stylomatic uppercase.c
Looks good!

You’ll get advice if you need to make changes to your code.

Submit your work with the give command, like so:

$ give cs1511 wk05_uppercase

Or, if you are working from home, upload the relevant file(s) to the wk05_uppercase activity on Give Online.
