To effectively prepare for the Secondary Education Examination (SEE) in Nepal, it's crucial to understand key programming concepts such as modular programming, procedures, sub-procedures, function procedures, and data file handling. Here's an overview of these topics:

Modular Programming:

Modular programming is a software design technique that emphasizes separating a program's functionality into independent, interchangeable modules. Each module contains everything necessary to execute a specific aspect of the program's functionality, enhancing code readability, maintainability, and reusability.

Procedures

Procedures are blocks of code designed to perform specific tasks within a program. They promote code reuse and simplify complex problems by breaking them into smaller sub-tasks. In QB programming, procedures can be categorized into two types:

Sub-Procedures and function procedure

example:
DECLARE FUNCTION CalculateAverage (num1, num2, num3)
DECLARE SUB SaveResult (average)

' Main program
DIM num1, num2, num3, average

' Input three numbers
INPUT "Enter first number: ", num1
INPUT "Enter second number: ", num2
INPUT "Enter third number: ", num3

' Calculate the average
average = CalculateAverage(num1, num2, num3)

' Display the result
PRINT "The average is "; average

' Save the result to a data file
CALL SaveResult(average)

END

' Function to calculate the average
FUNCTION CalculateAverage (num1, num2, num3)
CalculateAverage = (num1 + num2 + num3) / 3
END FUNCTION

' Sub-procedure to save the result to a data file
SUB SaveResult (average)
PRINT #1, "The average is "; average
CLOSE #1
END SUB
