What are the two errors in my pseudocode?Module getAverage(Integer value1, Integer value2, Integer value3)
Declare Integer average
average = value1 + value2 + value3 / 3
Display average
End Module
Where did I make an error in my pseudocode module???Code:Module main()
Call raiseToPower(2, 1.5)
End main
Module raiseToPower(Real value, Integer power)
Declare Real result
Set result = value ^ power
Display result
End raiseToPower
Why does my pseudocode not perform what I asked? Don't know whats wrong with it.// This program asks the user to enter a value
// between 1 and 10 and validates the input.
Declare Integer value
// Get a value from the user.
Display "Enter a value between 1 and 10."
Input value
// Make sure the value is between 1 and 10.
While value < 1 AND value > 10
Display "ERROR: The value must be between 1 and 10."
Display "Enter a value between 1 and 10."
Input value
End While

- I need help writing pseudocode for calculating class score average by putting in 5 test scores, and showing the average from all 5 inputs and the GPA score.Starting with 3 functions outside of a main module. The functions are getScore(), getGPAPoint(Integer score), and getAverage(). Function getscore is an input for a grade as a class percentage. Function getGPAPoint will calculate the score into a GPA point and return as a float (values of 90-100 as 4.0, 80-89 as 3.0, 70-79 as 2.0, 60-69 as 1.0, and anything below 60 as 0.) Function averageGPA will finally make a call to both previous functions when the user inputs numbers 5 times that then calculates the average (add up all the scores, divide by 5) and the average grade alongside displaying the average GPA. End result is a main module that makes a proper call to the averageGPA function and display its results.
