1st PUC Computer Science Arrays One Mark Questions and Answers<\/h3>\n

Question 1.
\nWhat is an Array?
\nAnswer:
\nArray is a group of similar elements that share a common name.<\/p>\n

Question 2.
\nWhat is the use of arrays?
\nAnswer:
\nThe use of arrays reduces the creation and use of more number of individual variables in a program. It also helps to reduce the program length.<\/p>\n

Question 3.
\nMention the different types of arrays.
\nAnswer:
\nThere are three types of arrays, namely<\/p>\n

    \n
  1. One dimensional array,<\/li>\n
  2. Two-dimensional array and<\/li>\n
  3. Multidimensional array<\/li>\n<\/ol>\n

    Question 5.
    \nWhat is zero-based indexing?
    \nAnswer:
    \nIf \u2018i\u2019 is the element, then its index number would be i-1 and it is called zero-based indexing.<\/p>\n

    Question 6.
    \nWhat is the subscript of the first element of an array?
    \nAnswer:
    \nThe first element i = 1, then subscript is 0 because of i-1 i.e., 1-1<\/p>\n

    Question 7.
    \nMention any one feature of subscript or index of an array.

    \nSubscript or index of an array is always a positive whole number.<\/p>\n

    Question 8.
    \nDefine a one-dimensional array.
    \nAnswer:
    \nOne dimensional array is a collection of similar elements that share a common name and is structured in one dimension only.<\/p>\n

    Question 9.
    \nGive the declaration syntax of a one-dimensional array.
    \nAnswer:
    \ndatatype array name [size];<\/p>\n

    Question 10.
    \nWhat is meant by initialization of an array?
    \nAnswer:
    \nInitialization means assigning values to the declared variables or arrays. To initialize an array, each and every element of the array has to be referred and then value assigned to it.<\/p>\n

    Question 12.
    \nDefine a two-dimensional array.
    \nAnswer:
    \nTwo-dimensional array is a collection of elements of similar type that share a common name, structured in two dimensions. Each element is accessed by two index values.<\/p>\n

    Question 13.
    \nWrite the declaration syntax of a two-dimensional array.
    \nAnswer:
    \nSyntax:
    \n<data-type> <array-name> [<size1>] [<size2>];<\/p>\n

    Question 14.
    \nGive an example of, how a two-dimensional array is declared?
    \nAnswer:
    \nint marks[5][5];<\/p>\n

    Question 15.
    \nGive one example showing initialization of a two-dimensional array.
    \nAnswer:
    \nExample of array initialization with declaration:
    \nint matrix [3] [3] = { 91,96,90,94,99,95,87,92,98};<\/p>\n

    Question 16.
    \nDeclare an array to store the 6 subject marks of 500 students.
    \nAnswer:
    \nInt marks [500] [6];<\/p>\n

    \"KSEEB<\/p>\n

    Question 17.
    \nHow an element in the two-dimensional array is accessed?
    \nAnswer:
    \nAn element in the two-dimensional array is accessed using two index\/subscript numbers. The first number indicates the row index and the second number indicates the column index.<\/p>\n

    Question 18.
    \nDefine multidimensional array.
    \nAnswer:
    \nA collection of similar elements structured in N dimensions where N>=1. Each element is accessed by N indices.<\/p>\n

    1st PUC Computer Science Arrays Two\/ Three Marks Questions and Answers<\/h3>\n

    Question 1.
    \nExplain any two uses of arrays.
    \nAnswer:
    \nIt reduces the creation and use of more number of individual variables in a program. Confusion and complexity in identifying the variables can be avoided.<\/p>\n

    Question 2.
