Programming Fundamentals Questions

Multiple choice technology programming languages

C++

  1. No

  2. Case sensitivity is compiler-determined

  3. Yes

  4. None of the Above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

This question lacks context, but C++ is a strictly case-sensitive programming language. Therefore, identifiers like myVar and myvar are treated as completely distinct.

Multiple choice technology programming languages

C++

  1. True

  2. False

  3. It depends on the variable type

  4. None of the Above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

This question lacks context, but in C++, whether a variable is automatically initialized or contains garbage values depends on its type and storage duration (e.g., global/static variables are zero-initialized, while local automatic variables are not).

Multiple choice technology programming languages

C++

  1. The snippet is illegal

  2. It loops forever

  3. It is ignored by compiler, but it is not illegal

  4. None of the Above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

This question lacks context, but like question 135521, it refers to an infinite loop construct (such as while(true) or for(;;)), which is syntactically legal and loops forever.

Multiple choice technology programming languages

C++

  1. Breaks out of the if statement

  2. Exits the function

  3. Nothing (Compiler error)

  4. None of the Above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

This question lacks context, but in C++, using a break statement outside of a loop or a switch block (such as directly inside an if statement) results in a compilation error.

Multiple choice technology programming languages

C++

  1. public

  2. protected

  3. guarded

  4. None of the Above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

This question lacks context, but 'guarded' is not a valid access specifier in C++. The standard C++ access specifiers are public, protected, and private. If the question asks for a non-C++ specifier, 'guarded' is correct.

Multiple choice technology programming languages

C++

  1. True

  2. False

  3. It depends on the variable type

  4. None of the Above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

In C++, true and false are bool keywords that convert to 1 and 0 respectively in integer contexts. However, the expression true == false is always false regardless of variable type because both are bool constants. The answer depends on context - for bool variables, only true and false values exist; for other types converted to bool, any non-zero value is true and zero is false.
