Microsoft Small Basic - Coding Project - Simple Calculator Program
Introduction
Are you interested in learning how to program in Microsoft Small Basic? If so, one great way to get started is by building a simple calculator program. This program will teach you how to use variables, user input and output, conditional statements, and arithmetic operators in Small Basic, while also providing a useful tool for performing calculations.
Variables
In programming, variables are like labeled containers that hold values. In Small Basic, you can create a variable by assigning a value to a name, like num1 = 10. Variables can hold different types of values, such as numbers or text, and can be used to store and manipulate data during the execution of a program.
User Input and Output
One of the most important features of Small Basic is its ability to interact with the user through input and output. You can use TextWindow.WriteLine to display text to the user, and TextWindow.ReadNumber to read numbers input by the user from the keyboard. By combining these functions, you can prompt the user for input and display the results of calculations.
Conditional Statements
Conditional statements allow a program to make decisions based on certain conditions. In Small Basic, you can use If and ElseIf statements to perform different actions based on user input or other conditions. By using these statements, you can create more complex and powerful programs that can adapt to different situations.
Arithmetic Operators
In programming, arithmetic operators are used to perform arithmetic calculations on values. Small Basic provides several arithmetic operators, including +, -, *, and /, which respectively represent addition, subtraction, multiplication, and division. By using these operators, you can perform calculations on the input values and display the results to the user.
Debugging
Debugging is an important part of programming, and it involves finding and fixing errors in the code. It's important to carefully check your code for errors and to test your program thoroughly to ensure that it works as intended.
Putting It All Together
Now that we've covered the basics of variables, user input and output, conditional statements, and arithmetic operators, let's put them all together into a simple calculator program. This program will prompt the user for two numbers and an operation, and then perform the requested operation and display the result. By following along with the code and explanations, you'll learn how to create your own programs in Small Basic.
How to Create and Run a Small Basic Program
To run a Small Basic program, you have two options: you can either use the Small Basic app, which you'll need to have installed on your computer, or you can use Small Basic Online, which is a web-based version of Small Basic. If you choose to use the Small Basic app, you'll need to create a new project by clicking on "File" and then "New", write your Small Basic program using the Small Basic language, and then save it with a .sb file extension. To run the program, simply click on "Run" or press F5 on your keyboard. The program will execute, and any output will be displayed in the console window.
Alternatively, if you choose to use Small Basic Online, you can create and run Small Basic programs directly in your web browser without needing to install any software. To get started, simply go to the Small Basic Online website and click on "New Program". You can then write your Small Basic program using the online editor, and then click on "Run" to execute the program. Any output will be displayed in the console window. By choosing the option that works best for you, you can easily create and run Small Basic programs on your computer or in your web browser.
Are You Ready to Begin?
Are you ready to begin coding this simple calculator program? Our discussion will include the following steps:
1. Console Display—We'll show you what the finished program will look like when it's executed in the console window.
2. Program Objective—We'll provide a one-sentence description of the program, explaining its purpose and significance.
3. Flowchart—We'll break down the logic of the program in sentence format, using a flowchart to illustrate the steps involved.
4. Pseudocode—We'll provide pseudocode for the program, showing you the basic structure and syntax of the code.
5. Source Code—We'll provide the complete source code for the program, including explanations of each line.
6. Line by Line Description of the Source Code—We'll explain each line of the source code in detail, including how it works and why it's important.
7. Sample Program Output—We'll provide an example console run of the program, showing you what the program looks like in action and how it responds to user input.
By following along with these steps, you'll gain a comprehensive understanding of the simple calculator program and the key concepts involved in programming. Whether you're a beginning Small Basic coder or an experienced programmer, this lesson will help you create your own programs with confidence.
Let's begin:
1. Console Display
This is what our program will look like when executed.
2. Program Objective
The program objective is to ask the user to enter two numbers and an operation, and then perform the requested operation and display the result.
3. Flowchart
4. Pseudocode
5. Source Code
6. Line by Line Description of the Source Code
Line 3: Display a prompt asking the user to enter the first number.
Line 4: Read the user's input and store it in the variable num1.
Line 6: Display a prompt asking the user to enter the second number.
Line 7: Read the user's input and store it in the variable num2.
Line 9: Display a prompt asking the user to enter the operation.
Line 10: Read the user's input and store it in the variable op.
Line 13-20: Check the value of op and perform the corresponding operation. Store the result in the variable result.
Line 23: Display the result to the user.
7. Sample Program Output
Conclusion
In this lesson, we've learned how to create a simple calculator program in Microsoft Small Basic, using a step-by-step process that introduces the key concepts involved in programming. We've covered variables, user input and output, conditional statements, and arithmetic operators, and combined these concepts into a complete program that performs basic arithmetic calculations. By following along with the program and the explanations provided, you should now have a solid understanding of the fundamentals of Small Basic programming.
