QBasic Download for Windows 7
If you are looking for a simple and easy way to learn programming, you might want to try QBasic. QBasic is a classic programming language that was developed by Microsoft in the early 1990s. It is based on the BASIC language, which stands for Beginners All-purpose Symbolic Instruction Code. QBasic is ideal for beginners because it has a simple syntax, a user-friendly interface, and a built-in debugger. In this article, we will show you how to download and install QBasic on Windows 7, as well as some basic tutorial and examples to get you started.
What is QBasic?
QBasic is an acronym for Quick Beginners All-purpose Symbolic Instruction Code. It was developed and launched by Microsoft in the year 1991 and is considered to be one of the most ideal languages for absolute beginners. It was intended as a replacement for GW-BASIC. QBasic was based on earlier QuickBASIC 4.5 compiler. It does not produce .exe files but instead generates files with extension .bas which can only be executed immediately by the built-in QBasic interpreter. It is based on DOS operating systems but is also executable on windows.

Step 1: Download QB64 from GitHub
The first step is to download the latest version of QB64 from GitHub. You can find the download link at . Choose the ZIP file that matches your operating system (Windows 32-bit or 64-bit). Save the file to your computer.
Step 2: Extract the ZIP file to a folder
The next step is to extract the contents of the ZIP file to a folder on your computer. You can use any file extraction software such as WinRAR or 7-Zip. Right-click on the ZIP file and choose Extract All or Extract Here. Choose a destination folder where you want to extract the files.
Step 3: Run the QB64.EXE file
The third step is to run the QB64.EXE file that is located in the folder where you extracted the files. Double-click on the file to launch the QB64 IDE (Integrated Development Environment). You should see a window like this:
The QB64 IDE consists of two windows: the Program Window (where you write your code) and the Immediate Window (where you see the output of your code). You can also access various menus and options from the toolbar at Step 4: Start Coding with QBasic
The final step is to start coding with QBasic. You can write your own code in the Program Window or load an existing program from the File menu. To run your code, press F5 or click on the Run button. You will see the output of your code in the Immediate Window or in a separate window, depending on the program. To stop your code, press ESC or click on the Stop button. You can also edit, debug, and save your code using the various options available in the IDE.
QBasic Tutorial and Examples
Now that you have downloaded and installed QBasic on Windows 7, you might want to learn some basic concepts and commands of QBasic. In this section, we will provide you with a brief tutorial and some examples of QBasic programs that you can try out.
Basic Syntax and Commands of QBasic
QBasic has a simple and easy-to-learn syntax that follows some basic rules. Here are some of them:
QBasic is not case-sensitive, which means you can use uppercase or lowercase letters interchangeably.
QBasic uses single-line comments that start with an apostrophe (') and end at the end of the line.
QBasic uses keywords that are reserved words that have a special meaning and function in the language. For example, PRINT, INPUT, IF, THEN, ELSE, etc.
QBasic uses variables that are names that represent values or data. Variables can be numeric (integer or floating-point) or string (text). Variables must start with a letter and can contain letters, numbers, or underscores (_).
QBasic uses operators that are symbols that perform arithmetic, logical, or relational operations on values or variables. For example, +, -, *, /, ^, =, , , etc.
QBasic uses expressions that are combinations of values, variables, operators, and parentheses that evaluate to a single value. For example, 2 + 3 * (4 - 1) is an expression that evaluates to 11.
QBasic uses statements that are instructions that tell the computer what to do. Statements can be simple (one line) or compound (multiple lines). Statements must end with a newline character or a colon (:).
QBasic uses functions that are predefined or user-defined subprograms that perform a specific task and return a value. Functions can be called by using their name followed by parentheses and arguments (if any). For example, SIN(30) is a function call that returns the sine of 30 degrees.
QBasic uses subroutines that are predefined or user-defined subprograms that perform a specific task but do not return a value. Subroutines can be called by using their name followed by parentheses and arguments (if any). Subroutines must be defined by using the SUB...END SUB keywords and can be ended by using the END SUB or EXIT SUB keywords. For example, SUB Greet (name$) PRINT "Hello,"; name$ END SUB is a subroutine definition that prints a greeting message.
Sample Programs in QBasic
To give you an idea of how QBasic programs look like and work, here are some sample programs that you can try out. You can copy and paste the code in the Program Window and run it by pressing F5.
Calculator Program
This program is a simple calculator that can perform addition, subtraction, multiplication, and division operations on two numbers entered by the user.
'Calculator Program CLS 'Clears the screen PRINT "Welcome to Calculator Program" PRINT "Enter two numbers:" INPUT "First number: ", num1 'Asks for the first number INPUT "Second number: ", num2 'Asks for the second number PRINT "Choose an operation:" PRINT "1. Addition" PRINT "2. Subtraction" PRINT "3. Multiplication" PRINT "4. Division" INPUT "Enter your choice: ", choice 'Asks for the choice of operation SELECT CASE choice 'Selects the appropriate case based on the choice CASE 1 'If choice is 1 result = num1 + num2 'Performs addition PRINT "The sum is "; result 'Prints the result CASE 2 'If choice is 2 result = num1 - num2 'Performs subtraction PRINT "The difference is "; result 'Prints the result CASE 3 'If choice is 3 result = num1 * num2 'Performs multiplication PRINT "The product is "; result 'Prints the result CASE 4 ' If choice is 4 IF num2 0 THEN 'Checks if the second number is not zero result = num1 / num2 'Performs division PRINT "The quotient is "; result 'Prints the result ELSE 'If the second number is zero PRINT "Division by zero is not possible" 'Prints an error message END IF CASE ELSE 'If choice is not valid PRINT "Invalid choice" 'Prints an error message END SELECT END 'Ends the program
Basic Game Program
This program is a basic game that asks the user to guess a random number between 1 and 10. The program gives feedback on whether the guess is too high, too low, or correct. The program ends when the user guesses the correct number or gives up.
'Basic Game Program CLS 'Clears the screen PRINT "Welcome to Basic Game Program" PRINT "I am thinking of a number between 1 and 10" PRINT "Can you guess what it is?" RANDOMIZE TIMER 'Initializes the random number generator num = INT(RND * 10) + 1 'Generates a random number between 1 and 10 DO 'Starts a loop INPUT "Enter your guess or 0 to quit: ", guess 'Asks for the user's guess IF guess = 0 THEN 'If the user enters 0 PRINT "You gave up" 'Prints a message EXIT DO 'Exits the loop ELSEIF guess = num THEN 'If the user guesses correctly PRINT "You got it" 'Prints a message EXIT DO 'Exits the loop ELSEIF guess num THEN 'If the user guesses too high PRINT "Too high, try again" 'Prints a message END IF LOOP 'Ends the loop END 'Ends the program
Clock Program
This program is a clock that displays the current time in hours, minutes, and seconds. The program uses the TIMER function to get the number of seconds since midnight and calculates the hours, minutes, and seconds accordingly. The program also uses the LOCATE and COLOR commands to position and color the text on the screen.
'Clock Program CLS 'Clears the screen COLOR 15, 0 'Sets the text color to white and the background color to black LOCATE 12, 30 'Positions the cursor at row 12 and column 30 PRINT "Clock Program" 'Prints the title of the program DO 'Starts a loop t = TIMER 'Gets the number of seconds since midnight h = t \ 3600 'Calculates the hours by dividing by 3600 and taking the integer part m = (t MOD 3600) \ 60 'Calculates the minutes by taking the remainder of dividing by 3600 and dividing by 60 and taking the integer part s = t MOD 60 'Calculates the seconds by taking the remainder of dividing by 60 LOCATE 14, 35 'Positions the cursor at row 14 and column 35 COLOR (h MOD 15) + 1, (m MOD 15) + 1 'Sets the text color and background color based on the hours and minutes PRINT USING "##:##:##"; h; m; s; 'Prints the time in hh:mm:ss format LOOP UNTIL INKEY$ "" 'Ends the loop when any key is pressed END 'Ends the program
