Calculating Your GPA (BASH script)

For this script we are going to build a small tool that will take in an x number of grade points and at the end spit out our average grade points and grade letter. For this script you will need

Name This Script: myGPA

To use a while loop since this loop will run for an x amount of time

Continues to prompt the user to enter their grade points

Stops prompting a user when the user enters 99. Use a break to exit the loop

DO NOT INCLUDE THE NUMBER 99 IN YOUR CALCULATIONS

Use the bc command since we are dealing with decimals

At the end spit out the average GPA along with the Grade Letter.

Equation: Add Up All The Numbers and then divide by the total numbers inputted (IGNORE THE NUMBER 99)

Use this chart to determine which grade letter to show

To compare floating point types (real numbers): while (( $(echo "$grade != 99" | bc ) ))

To add F.P. Type: sum=$(echo "scale=2;($sum+$grade)" | bc)

Grade Points	Grade Letter
4.00 and up	A
3.00 - 3.99	B
2.00 - 2.99	C
1.00 - 1.99	D
0.99 and below	F
