Introduction to Programming

To focus on the logic and make refinements to a program before translating it into a programming language, a programmer often creates an outline of the program’s algorithm. What is the term for this type of outline?

• Pseudocode
• Sketch
• Compiler
• Interpreter

Variables can hold different types of data, and they are classified based on the type of data they hold. The numbers 7.5, 2.1 and 48.6 would be stored using which variable data type?

• Boolean
• Floating Point
• String
• Integer

Veronica has written a computer program that locates records in a database. During testing, the program suddenly stops running. What is most likely causing the program to stop running?

• A runtime error
• A debugging error
• A logic error
• A syntax error

What is the only language that a computer can understand?

• High-level
• Application
• Machine
• Assembly

How is structured programming similar to a recipe?

• The steps must be performed in a certain order to produce the proper result
• The steps can be altered in any way without affecting the results.
• The steps may be performed in any order to produce the proper result.
• The steps must be repeated to produce the proper result.

Which type of error occurs when a programmer misspells a word or instruction?

• Runtime
• Syntax
• Logic
• System

Which control structure will execute an instruction only after the computer evaluates conditions to determine if a certain condition exists?

• Selection
• Loop
• Functional
• Sequence

Which term is used to describe expressions that result in the value of either true or false?

• Selection
• Boolean
• Conditional
• Concatenation

You are designing a computer program that calculates the amount of change a customer should receive. You create a program design document using the following pseudocode to demonstrate the program flow:  
item1 = input cost of item 1
item2 = input cost of item 2
item3 = input cost of item 3
total = item1 + item2 + item3
amtPaid = input amount paid
change = ________________  
Notice the blank at the end of the program. Which expression correctly completes the blank?

• amtPaid * item1 + item2 + item3
• amtPaid – total
• item1 + item2 + item3 – amtPaid
• total – amtPaid

1  Input a number
2  Check to see if the number ends in 0, 2, 4, 6 or 8?
 2a  If yes, write "The number is even."
 2b  If no, write "The number is odd."   This is an example of which type of control structure?

• Selection
• Iteration
• Loop
• Sequence
