    The correct option is B) x[] = {36, 78, 12, 24} and y[] = {36, 78, 12, 24}.
    The results after the given code was executed is x[] = {36, 78, 12, 24} and y[] = {36, 78, 12, 24}.

    What is array?

    An array is a group of elements the same type that are stored in adjacent memory locations and may be accessed individually by using a reference to a unique identifier.
    Some key features regarding the array are-
    • An array of five int values can be declared without having to declare five distinct variables (one with own identifier).
    • Because arrays are blocks containing static memory which size must be specified at compile time, the elements field inside square brackets [], denoting the amount of elements in the array, needs to be a constant expression.
    • Are left uninitialized by default. This indicates that none of its members are assigned a specific value; its contents are unknown at the time the array is defined.
    • The initializer can also be empty, with only the braces: { }
    Now, for the given programme,
    for(int a = 0; a < x.length; a++)
    {
    x[a] = y[a];
    y[a] = x[a];
    }
    After execution of the programme, the result obtain will be;
    x[] = {36, 78, 12, 24}
    y[] = {36, 78, 12, 24}.
    Therefore, the output of the given programme is obtained.

    The complete question is-
    What would be the results after the following code was executed?
    int[] x = {23, 55, 83, 19};
    int[] y = {36, 78, 12, 24};
    for(int a = 0; a < x.length; a++)
    {
    x[a] = y[a];
    y[a] = x[a];
    }
    A) x[] = {36, 78, 12, 24} and y[] = {23, 55, 83, 19}
    B) x[] = {36, 78, 12, 24} and y[] = {36, 78, 12, 24}
    C) x[] = {23, 55, 83, 19} and y[] = {23, 55, 83, 19}
    D) This is a compilation error.
