QBASIC program to calculate and display the sum of input two numbers

Introduction:

Are you interested in learning how to write a QBASIC program to calculate and display the sum of two input numbers? If so, you've come to the right place! In this article, we'll walk you through the process of creating a simple QBASIC program to calculate and display the sum of input two numbers

QBASIC is an old but powerful programming language that can be used to create a wide range of programs. If you're new to programming, QBASIC is a great language to start with as it is easy to learn and understand. So, let's get started and learn how to create a QBASIC program to calculate and display the sum of two input numbers.

Writing the QBASIC Program

To write the QBASIC program to calculate and display the sum of two input numbers, follow these steps:

Step 1: Define the Variables
Step 2: Get Input from the User
Step 3: Calculate the sum
Step 4: Display the sum

Complete coding

Explanation of Code

• The first line of the code, "CLS", clears the screen so that the program can start with a clean slate.
• The next two lines of code use the "INPUT" statement to prompt the user to enter two numbers. The first input statement asks the user to enter the first number, and the second input statement asks the user to enter the second number. The semicolon (;) after each input statement means that the input will be displayed on the same line as the prompt.
• The third line of code calculates the sum of the two input numbers and stores it in the variable "sum". The plus sign (+) is the addition operator in QBASIC, and it is used to add the two numbers together.
• The final line of code uses the "PRINT" statement to display the sum to the user. The semicolon (;) after "Sum of two numbers:" means that the sum will be displayed on the same line as the prompt.
• The last line of the code, "END", indicates the end of the program.

The above program can also be solved by using SUB and FUNCTION procedure
