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 repeatedExplanation
The 'for loop' construct was designed to repeat a task exactly, an exact number of times.Rate this question:

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() loopExplanation
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.Rate this question:

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.Rate this question:

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.Rate this question:

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. CompilerExplanation
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.Rate this question:
