Question 6

What term is used in the ending terminal symbol of a function flowchart?
A)Return
B)End
C)Function End
D)Function Return
E)None of the above

Accepted Answer

The standard term used for the ending terminal symbol of a function flowchart is "Return". This signifies the end of the function and the return of the control back to the calling function or program. While "End" is also commonly used, it may not always be clear if this signifies the end of the flowchart or the end of the function. "Function End" and "Function Return" are not commonly used terms.

Question 7

The term ________________ is used to describe any mechanism that accepts input,performs some operation that cannot be seen on the input,and produces output.
A)White box
B)Black box
C)White cube
D)Black cube
E)None of the above

Accepted Answer

The term "black box" is commonly used to describe any mechanism or system where the inner workings or operations cannot be seen or understood. The inputs and outputs can be observed, but the actual process or operations that take place inside the system are hidden from view.

Question 8

A __________ is a module that returns a value back to the part of the program that called it.
A)Function
B)For
C)Loop
D)While
E)None of the above

Accepted Answer

A function is specifically designed to return a value back to the part of the program that called it. For and while are loops, and although they can perform specific tasks, they do not necessarily have a return value.

Question 9

Which of the following errors occur when a real value is attempted to be assigned to an integer variable?
A)Integer value
B)Type mismatch
C)Conversion
D)Assignment
E)None of the above

Accepted Answer

A type mismatch error occurs when a real value is attempted to be assigned to an integer variable because these types are not compatible with each other. An integer variable can only hold whole number values, whereas a real variable can hold decimal values. Therefore, trying to assign a real value to an integer variable causes a type mismatch error.

Question 10

Library functions are built into the programming language,and can be called any time they are needed.

Accepted Answer

Library functions are built-in functions in programming languages that can be called whenever they are needed. Examples include functions for mathematical operations, string manipulation, and input/output operations. These functions are already available in the programming language and do not require any additional code to work.

Question 11

The function ______ specifies the return data type,name of the function,and the parameter variable(s).
A)Definition
B)Body
C)Header
D)statement
E)None of the above

Accepted Answer

The function header includes the function's return type, name, and parameters. The definition refers to the entire function, including the function header and body. The body contains the code that is executed when the function is called. Statements are individual lines or blocks of code within the function body.

Question 12

The variable r would contain the value ________ after the execution of the following statement.
Declare Integer i = 12
Declare Real r
Set r = toReal (i)
A)12
B)1.2
C)12.0
D)0.12
E)None of the above

Accepted Answer

The variable i is declared as an integer with the value of 12, and then it is converted to a real using the toReal function. This means that the value of i is now a real with the same value as its original integer value. Therefore, the variable r will contain the value of 12.0, as it is the equivalent real value of the integer 12.

Question 13

Which of the following statements is true after the execution of the following statement?
Set needANumber = random(5,10)
A)A random number is generated between 5 and 10.
B)The random number is assigned to the variable needANumber.
C)The numbers 5 and 10 are the arguments of the random number function.
D)All of the above
E)None of the above

Accepted Answer

The statement generates a random number between 5 and 10 (5 and 10 are the arguments of the random number function) and assigns it to the variable needANumber, thus all the given options are correct.

Question 14

The function _________ comprises one or more statements that are executed when the function is called.
A)Definition
B)Header
C)Body
D)Datatype
E)None of the above

Accepted Answer

The body of a function contains the actual code that is executed when the function is called. It can contain one or more statements, and is always enclosed in curly braces {}.

Question 15

Which function returns a string within a string?
A)Append
B)Concatenate
C)Contains
D)Substring
E)None of the above

Accepted Answer

The function Substring returns a substring within a string. It requires two parameters, the starting position and the length of the substring.

Question 16

Examine the following piece of code and determine the data type of the function's return value.
Function Real sum (Integer num1,Integer num2)
Declare Integer result
Set result = num1 + num2
Return result
End Function
A)Real
B)Integer
C)Sum
D)result
E)None of the above

Accepted Answer

The function is declared to return a Real data type, despite the operations within it dealing with Integer types. The actual return type is determined by the function declaration, not the types of variables it operates on.

Question 17

In the IPO chart,the _______ column describes the data that is passed to the function as arguments.
A)Output
B)Function
C)Process
D)Input
E)None of the above

Accepted Answer

The input column in the IPO chart lists the data that is passed to the function as arguments. This input is processed by the function, which results in some output. The output column of the IPO chart lists the data that is produced by the function as a result of processing the input. The function column of the IPO chart describes the operation or process that the function performs on the input to produce the output. Therefore, the correct choice is D, which corresponds to the input column of the IPO chart.

Question 18

The ________ function does the same thing as using the mathematical ^ operator.
A)cos
B)abs
C)sqrt
D)round
E)pow

Accepted Answer

The answer of The ________ function does the same thing...

Question 19

The parameter list that accepts arguments is optional in a function definition.

Accepted Answer

While a function can be defined without a parameter list, it will not accept any arguments if there is no parameter list. If a function is designed to accept arguments, a parameter list must be included in the function definition.

Question 20

Which function accepts two strings as arguments,returns "True" if the first string contains the second string,and otherwise returns "False"?
A)Append
B)Concatenate
C)Contains
D)Substring
E)None of the above

Accepted Answer

The function that fits the given description is the "Contains" function. This function checks if the second string is a substring of the first string and returns a Boolean value of True or False accordingly. The Append function is used to add an element to the end of a list, Concatenate function is used to join two or more strings together, and Substring function is used to extract a portion of a string based on a specific index range.
