The program will ask the user to enter 5 student names. For each of the students, the program will ask for 3 exam scores. The average exam score for each student will be calculated and printed. Analysis

I will use sequential and repetition programming statements. I will define one String to store the student name: StudentName. I will define three Float numbers: Examvalue, Sum, Avg to store exam values the sum of the exams and the average of the exams. The sum will be calculated by this formula: Sum = Sum + Examvalue For example, if the first value entered was 80.0 and second was 90.0 and the third exam was 100.0: sum = sum + Examvalue = 0.0 + 80.0 sum = 80.0 + 90.0 = 170.0 sum = 170.0 + 100.0 = 270.0 Avg is then calculated as: Avg = sum/3.0 For example 270.0/3.0 = 90.0 A nested repetition loop can be used to loop through each of the 5 students and each of the 3 exams: For (students=0; students <5; students++) For (exams=0;exams<3;exams++) End For End For Sum values will need to be reset for each student to ensure only one student data is used for calculations each time.Test Plan To verify this program is working properly the input values could be used for testing: Learning Exercises for you to complete 1.

The example provided uses sequential, repetition, selection statements and two user-defined function. Program Description

This program will provide options for a user to calculate the square or cube of a positive Integer input by a user. The program will prompt the user to enter an Integer and then prompt the user if they want to calculate the square of the cube of the number. Based on the inputs of the user, the program will output the square of the cube of the positive integer. The program will then print the Integer and square or cube of the integer based on the user’s original choice. The program will continue to prompt the user for Integers and their calculation choice until the user enters a negative integer. The square and cube calculations should be calculated using a function. Analysis I will use sequential, selection, and repetition programming statements and functions for the cube and square calculations. I will define three Integer numbers: IntValue, MenuSelect, Results to store the Integer value input by the user, the Menu selection (1 for Square, 2 for Cube) of the user, and the results of the Square or Cube functions. The Square function will take one Integer as input and return one Integer as the output. The calculation within the Square function is: Results = IntValue * IntValue For example: if 10 was entered as the IntValue. Results = 10*10 = 100 The Cube function will take one Integer as input and return one Integer as the output. The calculation within the Cube function is: Results = IntValue * IntValue*IntValue For example: if 10 was entered as the IntValue. Results = 10*10*10 = 1000 A repetition loop can be used to loop through iterations until a negative is entered: Learning Exercises for you to complete 1. Using the Square and Cube functions as models, Create an application that includes a function named “Shrink” that would take an Integer and return the Integer divided by 2?

Analysis, Design(program design, pseudocode), Test Plan, and implementation with C code. The example provided uses sequential, repetition, selection statements, functions, strings, and arrays. Program Description: This program will input and store meteorological data into an array. The program will prompt the user to enter the average monthly rainfall for a specific region and then use a loop to cycle through the array and print out each value. The program should store up 5 years of meteorological data. Analysis: I will use sequential, selection, and repetition programming statements and an array to store data. I will define a 2-D array of Float number: Raindata[][] to store the Float values input by the user. To store up to 5 years of monthly data, the array size should be at least 5*12 = 60 elements. A float number (rain) will also be needed to input the individual rain data. An integer variable (Count) is needed to keep count of how many rain data elements were entered. This will keep track to make sure we don’t go over 60 and we print only valid rain elements. In a 2D array this will be RainData[5][12]. We can use #defines to set the number of years and months to eliminate hard coding values. A float number (rain) will also be needed to input the individual rain data. A nested for loop can be used to iterate through the array to enter Raindata. A nested for loop can also be used to print the data in the array. A array of strings can be used to store year and month names. This will allow a tabular display with labels for the printout. Functions will be used to separate functionality into smaller work units. Functions for displaying the data and inputting the data will be used. A selection statement will be used to determine if data should be entered. Learning Exercises for you to try: 1. Modify the program to add a function to sum the rainfall for each year (Hint: you need to sum for each year. You can do this using a

looping structure) Support your experimentation with screen captures of executing the new code 2. Enhance the program to allow the user to enter another meteorological element such as windspeed (e.g. 2.4 mph). Note, the user should be able to enter both rainfall and windspeed in your new implementation. Support your experimentation with screen captures of executing the new code. 3. Prepare a new test table with at least 2 distinct test cases listing input and expected output for the code you created after step 2 4. What happens if you change the NUMMONTHS and NUMYEARS de finitions to other values? Be sure to useboth lower and higher values. Describe and implement fixes for any issues if errors results.
