101. Programs written in an assembly language require a(n) ____, which also is a program, to convert the assembly
- A.
Compiler
- B.
Assembler
- C.
Interpreter
- D.
Linker
Correct Answer
B. AssemblerExplanation
Programs written in an assembly language require an assembler, which is a program that converts the assembly code into machine code. The assembler translates the mnemonic instructions and symbolic labels into binary instructions and memory addresses that the computer can understand and execute. Unlike a compiler, which translates high-level languages into machine code, an assembler specifically works with assembly language. An interpreter, on the other hand, executes the source code directly without converting it into machine code. A linker, while important in the overall process of program execution, is not responsible for converting assembly code into machine code.Rate this question:

102. The repetition structure is also referred to as a loop or as ____.
- A.
Branch
- B.
Iteration
- C.
Select
- D.
Repeat
Correct Answer
B. IterationExplanation
The repetition structure is also referred to as a loop or as iteration. This is because in programming, a repetition structure allows a certain set of instructions to be repeated multiple times until a specific condition is met. The term "iteration" is commonly used to describe this process of repeating a set of instructions. Therefore, "iteration" is the correct answer as it is another commonly used term to refer to the repetition structure or loop in programming.Rate this question:

103. Some high-level languages use a(n) ____ rather than a(n) ____.
- A.
Interpreter, compiler
- B.
Assembler, interpreter
- C.
Assembler, compiler
- D.
Assembler, linker
Correct Answer
A. Interpreter, compilerExplanation
High-level languages use an interpreter rather than a compiler. An interpreter translates and executes the code line by line, converting it into machine code on the fly. This allows for immediate feedback and easier debugging. On the other hand, a compiler translates the entire code into machine code before execution, resulting in faster execution but a longer development cycle.Rate this question:

Correct Answer
B. ObjectsExplanation
In the Windows environment, various graphical elements such as check boxes, list boxes, and buttons are commonly used. These elements are referred to as objects because they are distinct entities that can be interacted with by the user. Unlike registers, which are low-level storage locations in the computer's hardware, or procedures, which are sequences of instructions, objects in the Windows environment provide a visual interface for users to interact with the system. Mnemonics, on the other hand, are memory aids or shortcuts used to remember information, and are not directly related to the graphical elements in the Windows environment.Rate this question:

123. After executing the following lines of code, the result will be ____.int average = 0;double test1 = 90.0;double test2 = 81.0;average = (test1 + test2) / 2;
- A.
85 assigned to average
- B.
85.5 assigned to average
- C.
6 assigned to average
- D.
A syntax error
Correct Answer
A. 85 assigned to averageExplanation
The given code calculates the average of test1 and test2 by summing them and dividing by 2. Since test1 is 90.0 and test2 is 81.0, the sum is 171.0. Dividing 171.0 by 2 gives us 85.0. However, the variable average is an integer type, so it can only store whole numbers. Therefore, the decimal part of 85.0 is truncated, and the final value assigned to average is 85.Rate this question:

124. The ____ statement tells the computer to convert the double number 3.1 to float, and then assign the result to a float variable named price.
- A.
Float price = 3.1;
- B.
Float price = static_cast3.1;
- C.
Float price = static_castfloat;
- D.
Float price = float3.1;
Correct Answer
B. Float price = static_cast3.1;Explanation
The correct answer is "float price = static_cast(3.1);" because the static_cast keyword is used to explicitly convert the double number 3.1 to a float data type. The syntax for static_cast is static_cast(expression), where new_type is the desired data type and expression is the value to be converted. In this case, the expression is 3.1 and the new_type is float, so the double value 3.1 is converted to a float and assigned to the variable named price.Rate this question:

Correct Answer
A. IfExplanation
An "if" selection structure contains only one set of instructions that are executed when the condition is true. This means that if the condition specified in the "if" statement evaluates to true, the instructions within the "if" block will be executed. In contrast, an "if/else" structure allows for two sets of instructions, one for when the condition is true and another for when it is false. The "switch" and "case" keywords are used for implementing multi-way selection structures, where different sets of instructions are executed based on the value of a variable.Rate this question:
