Unit 5: call by value

What is the default method of passing arguments in C?

• Call by Address

• Call by Value

• calling itself

• recursion

In Call by Value, changes made to parameters in the function:

• Affect the original arguments

• Do not affect the original arguments

• Change the data type

• Cause a runtime error

Which operator is used to access the address of a variable?

• ^

• *

• $

• &

Which method allows modifying the actual arguments?

• Call by Address

• Call by Value

• Call by Print

• self call

Every recursive function must have:

• Loop

• Exit condition (base case)

• Pointer

• Global variable

What happens if a recursive function has no base case?

• Infinite recursion leading to stack overflow

• Compiles but gives a warning

• Run once

• Gives segmentation fault at compile time

What is recursion?

• A loop inside a function

• A function calling another function

• A function not returning a value

• A function calling itself
