Questions and Answers
  • 1. 

    Programmers use their knowledge about a problem to choose how to solve it. If a programmer chose a  for loop, they probably knew what information about the problem being solved?

    • A. 

      How long each step of the solution would run

    • B. 

      How many times a specific step of the solution should be repeated

    • C. 

      How many different kinds of steps would be in the solution

    • D. 

      What user the problem should be solved for

    Correct Answer
    B. How many times a specific step of the solution should be repeated
    Explanation
    The 'for loop' construct was designed to repeat a task exactly, an exact number of times.

    Which of the following iteration constructs is most specialized for use with collections?

    • A. 

      The for() loops

    • B. 

      The foreach() loop

    • C. 

      The do{}while() loop

    • D. 

      The while() loop

    Correct Answer
    B. The foreach() loop
    Explanation
    The 'foreach' construct is used to execute a block of code once for each and every object in a collection. The advantage is that the programmer need not know exactly how many objects there are - C# knows.

    Which of the following iteration constructs evaluate their conditions after executing the statements they control?

    • A. 

      Do(){}

    • B. 

      While(){}

    Correct Answer
    B. While(){}
    Explanation
    The while() loop first evaluates its conditional statement, and then executes its controlled code-block, before beginning again. The 'do{}while()' construct is the reverse. The for() and foreach() also check conditions first, and are different in other ways also.

  • 4. 

    Given the for loop with the conditional “(int i 0; i <10; ... )”, what is the third sub-statement that would allow the loop to execute ten times?

    • A. 

      ++i

    • B. 

      I++

    • C. 

      I--

    Correct Answer
    B. I++
    Explanation
    The statements “++i” and “i++” will evaluate in larger statements in a different order, and so have different effects sometimes. Here, they are essentially being evaluated by themselves, and so they both increment 'i' ten times: from 0 to 10.

  • 5. 

    What is the software called that translates code into something meaningful the computer can understand?

    • A. 

      Converter

    • B. 

      Transliterator

    • C. 

      Translator

    • D. 

      Compiler

    Correct Answer
    D. Compiler
    Explanation
    A compiler is a software program that translates code written in a high-level programming language into a lower-level language, such as machine code, that can be understood and executed by a computer. It performs various tasks, including lexical analysis, syntax analysis, and code optimization, to convert the code into a format that the computer can understand and execute efficiently.
