Overview
This hands-on lab allows you to follow and experiment with the critical steps of developing a program including the program description, analysis, test plan, design, pseudocode visualization, and implementation with C code. The example provided uses mathematical operators and variable types. Program
Description
This program will calculate the area of a right triangle. The program will ask the user to enter the base and height and then use these values to calculate and then print the area of the triangle. The design step will include pseudocode.
Analysis
I will use sequential programming statements. I will define two float numbers for the base and height: base, height. Float numbers were selected as opposed to integers to make sure triangles of all dimensions are possible and not just whole numbers.
Float number will store the area: area
The area will be calculated by this formula
Area = ½ * (base * height)
For example if the base was 4.2 and the height was 5.3 the area would be calculated as:
Area = ½ * (4.2 * 5.3) = ½ * (22.26) = 11.13
Test Plan
To verify this program is working properly the following base and height values could be used for testing:

Week 4
Overview
This hands-on lab allows you to follow and experiment with the critical steps of developing a program including the program description, analysis, test plan, design (using pseudocode), and implementation with C code. The example provided uses sequential and selection statements.
Program Description
This program will calculate the sum of 5 integers. The program will ask the user to 5 integers. If the sumof the numbers is greater than 100, a message is printed stating the sum is over 100. The design step will include both pseudocode.
Analysis
I will use sequential, and selection programming statements.
I will define six integer numbers: value1, value2, value3, value4, value5 and sum. The value1, value2,value3, value4 and value5 variables will store the integers input by the user. The sum will store the sum of the 5 values.
The sum will be calculated by this formula:
sum = value1 + value2 + value3 + value4 + value5
For example, if the first values entered were value 1=1, value 2=1, value 3=2,value 4=2 and value 5=3 respectively:
sum = 1 + 1 + 2 + 2 + 3 = 9
The additional selection statement will be of this form:
If sum > 100 then
print “Sum is over 100”
End If Test Plan
To verify this program is working properly the input values could be used for testing:

Overview
This hands-on lab allows you to follow and experiment with the critical steps of developing a program including the program description, analysis, test plan, design (using pseudocode), and implementation with C code. The example provided uses sequential, selection and repetition statements.
Program Description
This program will calculate the average of 10 positive integers. The program will ask the user to 10 integers. If any of the values entered is negative, a message will be displayed asking the user to enter a value greater than 0. The program will use a loop to input the data.
Analysis
I will use sequential, selection and repetition programming statements. I will define two integer numbers: count, value and sum. count will store how many times values are entered. value will store the input. Sum will store the sum of all 10 integers. I will define one double number: avg. avg will store the average of the ten positive integers input.
The sum will be calculated by this formula:
Learning Exercises for you to complete
1. Change the code to average 20 integers as opposed to 10. Support your experimentation with screen captures of executing the new code.
2. Prepare a new test table with at least 3 distinct test cases listing input and expected output for the code you created after step 1.
3. What happens if you entered a value other than an integer? (For example a float or even a string). Support your experimentation with screen captures of executing the code.
4. Modify the code to allow the user to enter an unspecified number of positive integers and calculate the average. In other words, the user could enter number of positive integers. (Hint: You can prompt the user for how many they want to enter. Or; you could use a sentinel value to trigger when the user has completed entering values). You may need to conduct some research on your own to solve this problem. Prepare a new test table with at least 3 distinct test cases listing input and expected output for the code you created.

Overview
This hands-on lab allows you to follow and experiment with the critical steps of developing a program including the program description, analysis, test plan, design and implementation with C code. The example provided uses sequential, repetition statements and nested repetition statements.
Program Description
This program will calculate the average of 3 exams for 5 students. 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. Modify the code to be able to input an undetermined number of students. You will still only have 3 exams for each student. Support your experimentation with screen captures of executing the new code.
2. Prepare a new test table with at least 3 distinct test cases listing input and expected output for the code you created after step 1.
3. What is the line of code doing?
char StudentName[100];
(Hint: We haven’t covered arrays, but a String can be thought of as an array of characters) ?
4. What would happen if you moved the Set Sum = 0.0 from inside the for loop to right after the declaration. For example:
// Declare variables
Declare StudentName as String Declare ExamValue, Sum, Avg as Float
// Initialize Sum Set Sum = 0.0;
Support your experimentation with screen captures of executing the new code.

Overview:
This hands-on lab allows you to follow and experiment with the critical steps of developing a program including the program description, 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. Support your experimentation with screen captures of executing the new code.
