You use the relevant formula.
-- Think of a name for the sum, like 'S'.-- Tell qbasic what 'S' is the sum of.S = 41 + 61 + 2 + 84 + 136-- If you want to see it on the screen, thenPRINT Sand the sum pops up. It looks like this on the screen:324
To calculate the average of a set of numbers in QBasic, you first need to declare variables to store the sum and count of the numbers. You can use a loop to input the numbers, adding each one to the sum and incrementing the count. After the loop, divide the total sum by the count to get the average. Here’s a simple example: DIM sum AS SINGLE DIM count AS INTEGER sum = 0 count = 0 DO INPUT "Enter a number (or -1 to finish): ", num IF num <> -1 THEN sum = sum + num count = count + 1 END IF LOOP UNTIL num = -1 IF count > 0 THEN PRINT "Average: "; sum / count ELSE PRINT "No numbers entered." END IF
To write a program in QBasic that prints the sum of the even numbers from 1 to 20 in reverse order, you can follow these steps: DIM sum AS INTEGER sum = 0 FOR i = 20 TO 2 STEP -2 sum = sum + i NEXT i PRINT "The sum of even numbers from 1 to 20 is: "; sum This program initializes the sum to zero, iterates from 20 down to 2 in steps of -2 (to capture even numbers), adds each even number to the sum, and finally prints the result.
To arrange numbers in ascending order in QBASIC, you can use a simple sorting algorithm like bubble sort. First, store the numbers in an array. Then, repeatedly compare adjacent elements and swap them if they are in the wrong order until the entire array is sorted. Here's a basic example: DIM numbers(5) AS INTEGER ' (Assume numbers are already populated) FOR i = 0 TO 4 FOR j = 0 TO 4 - i - 1 IF numbers(j) > numbers(j + 1) THEN SWAP numbers(j), numbers(j + 1) END IF NEXT j NEXT i This will sort the array numbers in ascending order.
In QBasic, there are several fundamental data types, including numeric types (such as INTEGER, SINGLE, and DOUBLE) for storing numbers, and STRING for text. The INTEGER type stores whole numbers, while SINGLE and DOUBLE can represent floating-point numbers with varying precision. Additionally, QBasic supports the BOOLEAN type for true/false values. Arrays can also be used to store multiple values of the same data type.

Cls input "enter two no.s ",a,b sum=a+b print "sum = ";sum end
Statement numbers were a feature of BASIC, and while QBASIC supports them, they are by no means necessary.

In QBASIC, you can write a simple program to input the number 64751315 and sum its digits as follows: DIM sum AS INTEGER sum = 0 INPUT "Enter a number: "; number FOR i = 1 TO LEN(number) sum = sum + VAL(MID$(number, i, 1)) NEXT PRINT "The sum of the digits is "; sum This program prompts the user to input a number, iterates through each digit, converts it to an integer, and adds it to the total sum, which is then printed out.
You need a code that can run to print even numbers between 10 and 100 using the qbasic command.
Most computer languages use the asterisk, "*", for multiplication.

To add the numbers together is the sum!!!! to add the numbers together is the sum!!!!
you do this 10 print "0112358132134" use the whole of the thing
