SEQUENTIAL PROGRAMMING MCQS

What is an identifier in programming?

• A reserved keyword
• A named entity for data or function
• A mathematical operator
• A data type in Python

In C++, what does a constant represent?

• A variable that can change its value
• A memory address
• A value that remains constant throughout the program
• A function with no return type

How does a variable differ from a constant in programming?

• Variables are immutable, constants are mutable
• Constants store changing values, variables store fixed values
• Variables can be reassigned, constants cannot
• Constants are only used in object-oriented programming

What is a "class" in object-oriented programming?

• A blueprint for creating objects
• A data type
• A constant variable
• A loop structure

What distinguishes a function from a method?

• Functions are not part of classes, methods are
• Methods are used for mathematical operations, functions for logic
• Functions are called with parentheses, methods are not
• Functions are only used in procedural programming

Why is recursion important in programming?

• It reduces code complexity
• It saves memory
• It allows a function to call itself
• It speeds up program execution

Which of the following is a common data type?

• Algorithm
• Loop
• Integer
• Function

What is the purpose of operators in programming?

• They perform operations on data
• They declare variables
• They define classes
• They control program flow

What do control flow statements regulate in sequential programming?

• Data types
• Execution order
• Memory allocation
• Input and output

In "Pass by Value," what is passed to the function?

• The memory address of the argument
• The actual value of the argument
• A reference to the argument
• The function itself
