CMIS 102 Week 2 Hands-On Lab NEW

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.

Program Description

This program will sum two integer numbers to yield a third integer number. Once the calculations are made the results of all the numbers will be printed to the output screen.

Analysis

We will use sequential programming statements.

We will define 3 integer numbers: a, b, c.

c will store the sum of a and b.

Test Plan

To understand this program the following input numbers could be used for testing:

a = 10
b = 20
c = a + b = 10 + 20 = 30

In table format the following results are expected:

Learning Exercises for you to complete

2. Prepare a new test table with at least 3 distinct test cases listing input and expected output for the product of two integers.

3. Change the C code to calculate the quotient (e.g. a/b) of two floats (e.g. 2.3/1.5).Hint: Use float variable types as opposed to integers. What happens if the denominator is 0.0? Support your experimentation with screen captures of executing the new code

4. Prepare a new test table with at least 3 distinct test cases listing input and expected output for the quotient of two floats.

CMIS 102 Week 3 Hands-On Lab NEW

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 &gt; 100 then
print &quot;Sum is over 100&quot;
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.

CMIS 102 Week 7 Hands-On Lab NEW

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, 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? (Hint: your returned value should probably be a double type.) 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 would happen if you removed the following code from our design? If intValue > 0 Support your argument with screen captures of executing the new code.

4. Modify the original code and add an additional function of your choice. The function should be unique and something you created for this assignment.
