1/10 Questions

Which of these programming languages does have support for multi-dimensional arrays?
- C
- FORTRAN
- COBOL
- Ruby

About This Quiz

Programmers who are in the know consider it a useful data structure which consists of a number of variables and values. Each variable that is associated with an element is often identified by a key or index. Do you know each array can be computed using a certain mathematical formula? Try this quiz now!

Programming Test: Arrays And Loops - Quiz

2.

Which of these does not require arrays?
- Heaps
- String
- Queues
- Loops
Correct Answer

A. Loops

Explanation

Loops do not require arrays. Loops are control structures used to repeatedly execute a block of code until a certain condition is met. They can be implemented using variables, conditions, and iteration statements, without the need for arrays. Arrays, on the other hand, are data structures used to store and manipulate collections of elements of the same type. Heaps, strings, and queues can all be implemented using arrays or other data structures, but loops do not inherently require arrays.

3.

Which of these connotes condition?
- IF
- @IT#
- Can
- Ahrefs
Correct Answer

A. IF

Explanation

The correct answer is "IF" because "IF" is a conditional word that introduces a condition or a hypothetical situation. It is commonly used in conditional statements or clauses to express a possibility or a requirement that must be met for something else to happen.

Which of these is not used to pack these parameters?
- Vector processor
- Dope vector
- String
- Lists
Correct Answer

A. Dope vector

Explanation

A dope vector is not used to pack these parameters. A dope vector is a data structure used in some programming languages to store additional information about an array, such as its size, dimensions, and element type. It is not used specifically for packing parameters. Parameters can be packed using other methods such as using a vector processor, strings, or lists.

What element does ALGOL use?
- Do
- Can
- For
- Will
Correct Answer

A. For

Explanation

ALGOL uses the element "For" in its programming language. "For" is a control structure used for looping and iterating over a set of values or a range of numbers in ALGOL. It allows the programmer to specify the starting point, end point, and the increment or decrement value for the loop. This element is crucial in ALGOL as it enables the execution of repetitive tasks and helps in writing efficient and concise code.

6.

What element does Fortran use?
- Do
- For
- Is
- Can
Correct Answer

A. For

Explanation

Fortran uses the "Do" element. In Fortran, the "Do" statement is used for loop control. It allows a specific block of code to be repeated a certain number of times or until a certain condition is met. The "Do" element is an essential part of the Fortran programming language and is used for efficient and structured looping in order to perform repetitive tasks.

7.

How many parts does a for-loop have?
- Two parts
- Nine parts
- Four parts
- Six parts
Correct Answer

A. Two parts

Explanation

A for-loop has two parts: the initialization and the loop condition. The initialization is where the loop variable is initialized, and the loop condition is where the condition for the loop to continue running is specified. These two parts work together to control the iteration of the loop, allowing it to execute statements repeatedly until the loop condition becomes false.

8.

What does the header of a for-loop specify?
- End
- Array
- List
- Iteration
Correct Answer

A. Iteration

Explanation

The header of a for-loop specifies the iteration. It contains the initialization, condition, and increment/decrement statements that control how many times the loop will execute. The iteration is the number of times the loop will repeat its block of code before terminating.

9.

Which of these is not a type of for-loop?
- Traditional for-loops
- Iterator-based for-loops
- Special for-loops
- Vectorised for-loops
Correct Answer

A. Special for-loops

Explanation

The given correct answer is "Special for-loops." This is not a type of for-loop because it is not a commonly recognized or widely used category of for-loop. Traditional for-loops, iterator-based for-loops, and vectorized for-loops are all well-known types of for-loops that are commonly used in programming. However, "Special for-loops" is not a recognized category and therefore not a valid option.

10.

Which of these languages does not support for-loops?
- BASIC
- Modula
- Python
- Pascal
Correct Answer

A. Python

Explanation

Python does not support for-loops. Unlike BASIC, Modula, and Pascal, Python uses a different syntax for loops called "while" loops. While loops allow the execution of a block of code repeatedly as long as a certain condition is true, whereas for-loops are used to iterate over a sequence or range of values a specific number of times. Therefore, Python is the correct answer as it does not have a built-in for-loop construct.
