In QBasic, the READ statement is used to read data from a data list that has been previously defined using the DATA statement. This allows programmers to input a series of values that can be retrieved later in the program. The READ statement retrieves values sequentially, so each call to READ fetches the next value in the data list. This is useful for initializing variables with predefined data without hardcoding them directly in the program.

Differentiate between conditional and unconditional controls in qbasic?
A 'conditional' statement is a logical test while unconditional statement will cause the computer to branch.
Write a qbasic program to display A NEW LINE?
In QBasic, you can display a new line using the PRINT statement. To create a new line, you can simply use an empty PRINT statement. Here’s a simple example: PRINT "This is the first line." PRINT ' This will create a new line. PRINT "This is the third line." This program will display the first line, then move to a new line, followed by the third line.
How to divide to numbers in qbasic?
In QBasic, you can divide two numbers using the division operator /. For example, to divide the variable a by b, you would write result = a / b, where result stores the outcome of the division. Ensure that b is not zero to avoid a division by zero error. You can then use the PRINT statement to display the result, such as PRINT result.
How to make 1 to 10 squares in qbasic?
In QBASIC, you can create squares from 1 to 10 by using a loop and the LINE statement. Here's a simple example: FOR i = 1 TO 10 LINE (10, 10 * i)-(10 + i * 10, 10 * i + i * 10), , B NEXT i This code will draw squares of increasing size, starting from 1x1 to 10x10, with their bottom-left corners positioned vertically. Adjust the coordinates in the LINE statement to position the squares as needed.

How do you stop a program from running in QBASIC?
To stop a program from running in QBASIC, you can press "Ctrl" + "Break" on your keyboard. This interrupts the program execution and returns you to the QBASIC command prompt. Alternatively, you can close the QBASIC window to terminate the program. If you want to exit gracefully, you can also use the END statement in your code to stop execution at a specific point.
What command statement terminates the qbasic program?
END '...END of program/halt program code execution. *NOTE*: There should be only 'one' END statement written inside of a QBASIC program. I have seen example code where they use multiple END statements; this is wrong!
How do you fill a triangle in qbasic graphics?
In QBasic graphics, you can fill a triangle using the PUT statement along with the LINE statement to draw the triangle's outline, and then use the FILL statement to fill the interior. First, define the triangle's vertices by specifying their coordinates, then use LINE to connect these points. After outlining the triangle, you can use the FILL statement to fill it with a specified color. Make sure you have the graphics mode set up properly using SCREEN before drawing.
