Question
Chapter 4, Problem 1RETC
Program Plan Intro
Central Processing Unit (CPU):
CPU is a part of computer hardware which has computer instructions to perform every operation in a system.
Expert Solution & Answer
Explanation of Solution
Function of a CPU:
The functions of a CPU is categorized into four ways. They are:
- Fetch the instructions.
- Decode and interpret the instructions.
- Fetch and process the data
- Write the data
Fetch the instructions:
Every instruction in CPU has stored in memory with its own address. The processor fetch the address and track the instruction for operation.
Decode and interpret the instructions:
The computer programs should be translated into assembly language for its execution. So, the processor should decode the given
Fetch and process the data:
Executing the instruction is another function in CPU processing. This function has three ways. They are: calculation with ALU, moving data from one to another memory location, and jump to different address.
Write the data:
The output data from all process written into the memory of the CPU.

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.
