Write a C program for a mini calculator using only the command line options. You must use getopt to parse the command line.

Usage: minicalc [-a num] [-d num] [-m num] [-s num] [-e] value The variable value is the starting value.

• Value should be validated to be an integer between 1 and 99. Error message and usage shown if not.

• -a adds num to value. • -d divides value by num.

• -m multiplies value by num. • -s subtracts num from value.

• -e squares value. (Note: no num is needed.)

• Output should have exactly 2 decimal places no matter what the starting values are.

• If -e is included, it is executed first.

• Use standard order of operations for all operations.

Code should be nicely indented and commented.

Create a simple Makefile to compile your program into an executable called minicalc. You should submit the source code, your Makefile and a screenshot of the output file.
