A Syntax Error is ?
- A.
An error you will never find
- B.
An error you find at the end when the program gives out a wrong value due to logic error.
- C.
An error caused by language rules being broken.
- D.
An error due to user error
Correct Answer
C. An error caused by language rules being broken.Explanation
A Syntax Error is an error caused by language rules being broken. Syntax refers to the rules and structure of a programming language. When these rules are violated, the program cannot be executed properly, resulting in a syntax error. It can occur due to various reasons such as misspelled keywords, missing semicolons, incorrect indentation, or using incorrect syntax for a specific programming construct.Rate this question:

Which data structure uses LIFO?
- A.
Array
- B.
Int
- C.
Stacks
- D.
Queues
Correct Answer
C. StacksExplanation
Stacks use the LIFO (Last-In, First-Out) principle, where the last element added to the stack is the first one to be removed. This means that elements are added and removed from only one end of the stack, known as the top. When a new element is added, it is placed on top of the stack, and when an element is removed, it is always the topmost element that gets removed. This behavior is similar to a stack of plates, where you can only add or remove plates from the top. Therefore, stacks are the data structure that uses LIFO.Rate this question:

Enter a one line comment that has the comment-- section is commented
Correct Answer
//section is commented
//Section is commented
//section is Commented

What is FIFO?
- A.
First in Few Out
- B.
Few In Few out
- C.
First In First Out
- D.
Few In First Out
Correct Answer
C. First In First OutExplanation
FIFO stands for First In First Out. It is a method of organizing and manipulating data structures, where the first element that is inserted into the structure is the first one to be removed. This means that the items are processed in the order they arrive, similar to a queue. The correct answer is "First In First Out" because it accurately describes the concept of FIFO.Rate this question:

A memory location that holds a single letter or number is called _________.
- A.
Double
- B.
Int
- C.
Char
- D.
Word
Correct Answer
C. CharExplanation
A memory location that holds a single letter or number is called a "char". It is a data type in programming that represents a single character, such as a letter or a number. The char data type is commonly used to store individual characters or small integers in computer memory.Rate this question:

A do-while and a while loop are the same. State true or false.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
False. A do-while loop and a while loop are not the same. The main difference between them is that a do-while loop will always execute the code block at least once, regardless of whether the condition is true or false. In contrast, a while loop will only execute the code block if the condition is true.Rate this question:

A short sections of code written to complete a task.
- A.
Buffer
- B.
Array
- C.
Function
- D.
Loop
Correct Answer
C. FunctionExplanation
A function is a short section of code written to complete a task. It is a reusable block of code that can be called multiple times within a program to perform a specific action. Functions are used to organize code, improve code readability, and promote code reusability. They can accept input parameters, perform calculations or operations, and return a value or result. In this context, a function would be the correct answer as it best describes a small section of code designed to accomplish a specific task.Rate this question:

Int hold decemals numbers
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The statement "Int hold decemals numbers" is incorrect. In programming, the "int" data type is used to store whole numbers, not decimal numbers. To store decimal numbers, the "float" or "double" data types are used. Therefore, the correct answer is False.Rate this question:

One loop inside the body of another loop is called
- A.
Loop in loop
- B.
Nested
- C.
Double loops
Correct Answer
B. NestedExplanation
When one loop is placed inside the body of another loop, it is referred to as a nested loop. This allows for the repetition of a set of instructions within another set of instructions. The inner loop will execute completely for each iteration of the outer loop, resulting in a nested structure. This concept is commonly used in programming to solve complex problems and perform tasks that require multiple iterations.Rate this question:

What dose this equation mean ? a != t
- A.
A is assinged t
- B.
A and t are equal
- C.
A is not equal to t
- D.
T is add to a
Correct Answer
C. A is not equal to tExplanation
The equation "a != t" means that a is not equal to t. It is a comparison statement that checks if the value of a is not the same as the value of t. If a and t are equal, the equation would be false.Rate this question:
