OCR KS5 Programming Concepts Quiz

What is a Branching in programming?

• A subroutine that is called to perform a task or calculation and always return a value.

• A programming control structure where the code selects one or more alternative paths depending on the evaluation of a boolean expression.

• A variable declared within a subroutine of a program, which only exists and can be used within that subroutine.

• A programming paradigm where the system is viewed as a set of objects, each with their own data and procedures.

What is the purpose of Functions in programming?

• To declare a variable in the main program which exists outside any of the subroutines.

• To break down a complex problem into simpler, self-contained components called modules.

• To create a temporary local copy of the actual value of a variable and passing it into the procedure.

• To perform a task or calculation and always return a value.

What are Global Variables?

• Variables that can only be used within the subroutine they are declared in.

• Variables declared in the main program which exist outside any of the subroutines, but can be used anywhere in the program.

• The data structures required to be passed into a subroutine.

• The address or pointer of the required value passed into a procedure.

What is an Integrated Development Environment (IDE)?

• A set of objects, each with their own data and procedures, that interact with each other.

• A subroutine that can be called by simply writing its name in the code.

• A software package that allows a user to develop and implement code more easily, with features for editing, debugging, version control, testing and compilation.

• The technique of breaking down a complex problem into simpler, self-contained components called modules.

What is Modularity in programming?

• A programming control structure where a set of statements is repeated either a fixed number of times or until a condition is met.

• The technique of breaking down a complex problem into simpler, self-contained components called modules.

• Passing the address or pointer of the required value into a procedure.

• A programming paradigm where the system is viewed as a set of objects.

What is Object Oriented Programming?

• A programming control structure where the code selects one or more alternative paths depending on the evaluation of a boolean expression.

• A subroutine that can be called to perform a task or calculation and always return a value.

• A programming paradigm where the system is viewed as a set of objects, each with their own data (attributes) and procedures (methods), that can interact with each other.

• A software package that allows a user to develop and implement code more easily.

What does Parameter passing by reference mean?

• Creating a temporary local copy of the actual value of a variable and passing it into the procedure.

• The data structures required to be passed into a subroutine.

• Passing the address or pointer of the required value into a procedure.

• A subroutine that is called by simply writing its name in the code.

What is the difference between Parameter passing by value and Parameter passing by reference?

• Parameter passing by value involves passing the address or pointer of the value, while parameter passing by reference involves creating a local copy of the value.

• Parameter passing by value involves creating a local copy of the value, while parameter passing by reference involves passing the address or pointer of the value.

• There is no difference; both methods pass the value directly into the subroutine.

• Parameter passing by value is used in object-oriented programming, while parameter passing by reference is used in procedural programming.

What are Parameters in the context of programming subroutines?

• The data structures required to be passed into a subroutine.

• A variable declared within a subroutine of a program.

• A programming control structure where the code selects paths depending on a boolean expression.

• A technique of breaking down a complex problem into simpler components.

What are Procedures in programming?

• A subroutine that is called by simply writing its name in the code and does not have to return a value.

• A variable declared in the main program which exists outside any of the subroutines.

• A software package that allows a user to develop and implement code more easily.

• The technique of breaking down a complex problem into simpler, self-contained components called modules.
