3.7 Performance AssessmentPre-Defined Functions using ctype.h and stdio.h

In this assessment, you will write a C code for a program that uses functions from the ctype.h and stdio.h header files.  This program asks the user to enter a character and then displays a message based on its case using the  isupper() and  islower() functions.

The functions used in this program include:

· puts() from the stdio.h header file -  puts() displays string data

· islower() and  isupper() from the ctype.h header file -  islower() checks to see if a letter is lowercase and  isupper() checks to see if a letter is uppercase.

Follow these instructions to complete your assignment:

1. Write C code for a program that does the following:

· Uses the puts() function to prompt the user to enter a letter and the scanf() function to store the letter the user enters.

· Uses the islower() and isupper with if() statements to determine the case of the letter

· Messages should be displayed based on the outcome of the if condition

2. Submit the following files:

· A screenshot of your output including the Title Bar of the console window .docx file
