Introduction To Arrays: Basic Test Quiz! - Quiz

Do you know what an array is used for programming? It is used as a data structure that is associated with elements in the form of variables and values. Each array can be identified by a key or index that distinguish it from others. Do you know what the simplest type of data structure is called? Take this quiz if you do!


Questions and Answers
  • 1. 

    What is the simplest type of data structure?

    • A.

      Linear array 

    • B.

      Key array 

    • C.

      Index array 

    • D.

      Complex array 

    Correct Answer
    A. Linear array 
    Explanation
    A linear array is the simplest type of data structure because it is a basic and straightforward way of organizing data. It consists of a sequence of elements where each element is accessed by its position or index. It does not involve any complex relationships or hierarchies like other data structures such as trees or graphs. Therefore, a linear array is considered the simplest type of data structure due to its simplicity and ease of implementation.

    What is the memory address of the first element of an array called?

    • A.

      Primary address 

    • B.

      Secondary address 

    • C.

      Tertiary address 

    • D.

      Lone address 

    Correct Answer
    A. Primary address 
    Explanation
    The correct answer is "Primary address". In computer memory, the primary address refers to the memory location where the first element of an array is stored. Arrays are stored in contiguous memory locations, and the primary address represents the starting point of the array. This address is used to access and manipulate the elements of the array.

    What are two-dimensional arrays called?

    • A.

      Primary foundation 

    • B.

      Secondary foundation 

    • C.

      Matrices 

    • D.

      Key 

    Correct Answer
    C. Matrices 
    Explanation
    Two-dimensional arrays are called matrices because they are structured in rows and columns, similar to a mathematical matrix. Matrices are used to store and organize data in a tabular format, making it easier to access and manipulate specific elements within the array.

    Which of these are often implemented in the form of arrays?

    • A.

      Foundation

    • B.

      Matrices 

    • C.

      Tables 

    • D.

      Keys 

    Correct Answer
    C. Tables 
    Explanation
    Tables are often implemented in the form of arrays. Tables are data structures that store information in rows and columns, similar to a spreadsheet. Arrays, on the other hand, are a data structure that stores a fixed-size sequence of elements of the same type. Since tables have a fixed number of rows and columns, they can be implemented using arrays, where each element in the array represents a cell in the table. This allows for efficient storage and retrieval of table data.

    Which of these is used as a synonym of array?

    • A.

      Tables 

    • B.

      Matrices 

    • C.

      Index 

    • D.

      Key 

    Correct Answer
    A. Tables 
    Explanation
    Tables can be used as a synonym of array because both refer to a structured arrangement of data. In both cases, the data is organized in rows and columns, allowing for efficient storage and retrieval. Just like an array, a table can hold multiple values and can be accessed using indexes or keys. Therefore, tables can be considered as a synonym for arrays in the context of data organization and storage.

  • 6. 

    Which of these is not a data structure?

    • A.

      Array 

    • B.

      String 

    • C.

      Table 

    • D.

      List 

    Correct Answer
    C. Table 
    Explanation
    The correct answer is "Table". A table is not considered a data structure in the traditional sense. It is a way of organizing data into rows and columns, typically used in databases or spreadsheets. Data structures, on the other hand, refer to specific ways of organizing and storing data in a computer's memory, such as arrays, strings, and lists.

    Rate this question:

  • 7. 

    Which of these are often optimized for array operations?

    • A.

      Indices 

    • B.

      Tables 

    • C.

      Power 

    • D.

      Vector processors 

    Correct Answer
    D. Vector processors 
    Explanation
    Vector processors are often optimized for array operations. Array operations involve performing the same operation on multiple elements of an array simultaneously. Vector processors are designed to efficiently execute these operations by utilizing parallel processing techniques and specialized hardware. This allows for faster execution of tasks such as mathematical calculations, data manipulation, and scientific simulations that involve large arrays of data.

  • 8. 

    Which of these is not a method of implementing array structures?

    • A.

      Tables 

    • B.

      Linked lists 

    • C.

      Strings

    • D.

      Searched lists 

    Correct Answer
    C. Strings
    Explanation
    Strings are not a method of implementing array structures. Arrays are used to store multiple values of the same data type, while strings are used to store a sequence of characters. Although strings can be stored in arrays, they are not a method of implementing array structures themselves. Instead, strings can be implemented using character arrays or linked lists.

    Who wrote the first arrow-sorting program?

    • A.

      Venn Euler 

    • B.

      Philip Emeagwali 

    • C.

      John Carson

    • D.

      John von Neumann

    Correct Answer
    D. John von Neumann
    Explanation
    John von Neumann is credited with writing the first arrow-sorting program. He was a Hungarian-American mathematician and computer scientist who made significant contributions to the development of computer architecture and programming. Von Neumann's work laid the foundation for modern computing, and his arrow-sorting program was an early example of using algorithms to solve complex problems.
