    How to reference all the elements in a one-dimension array?

    Best Answer
    Ask The Science

    It can be done by using an indexed loop such that the counter runs from 0 to the array size minus one. In this manner, you can reference all the elements in sequence by using the loop counter as the array subscript.

    How are the elements of a 2D array are stored in the memory?

    Best Answer
    Ask The Science

    There are two techniques by using which, the elements of a 2D array can be stored in the memory. Row-Major Order: In row-major ordering, all the rows of the 2D array are stored in the memory contiguously. First, the 1st row of the array is stored in the memory completely, then the 2nd row of the arrRead more

    Calculate the address of a random element present in a 2D array, given base address as BA.

    Best Answer
    Ask The Science

    Row-Major Order: If the array is declared as a[m][n] where m is the number of rows while n is the number of columns, then the address of an element a[i][j] of the array stored in row-major order is calculated as,   Address(a[i][j]) = B. A. + (i * n + j) * size Column-Major Order: If the array iRead more

    Row-Major Order: If the array is declared as a[m][n] where m is the number of rows while n is the number of columns, then the address of an element a[i][j] of the array stored in row-major order is calculated as,

     

    Address(a[i][j]) = B. A. + (i * n + j) * size

    Column-Major Order: If the array is declared as a[m][n] where m is the number of rows while n is the number of columns, then the address of an element a[i][j] of the array stored in column-major order is calculated as

    Address(a[i][j]) = ((j*m)+i)*Size + BA.

    Are linked lists considered linear or non-linear data structures?

    Best Answer
    Ask The Science

    A linked list is considered both linear and non-linear data structure depending upon the situation. Based on data storage, it is considered a non-linear data structure. Based on the access strategy, it is considered a linear data structure.

    What are the advantages of Linked List over an array?

    Best Answer
    Ask The Science

    The size of a linked list can be incremented at runtime which is impossible in the case of the array. The List is not required to be contiguously present in the main memory, if the contiguous space is not available, the nodes can be stored anywhere in the memory connected through the links. The ListRead more

    • The size of a linked list can be incremented at runtime which is impossible in the case of the array.
    • The List is not required to be contiguously present in the main memory, if the contiguous space is not available, the nodes can be stored anywhere in the memory connected through the links.
    • The List is dynamically stored in the main memory and grows as per the program demand while the array is statically stored in the main memory, the size of which must be declared at compile time.
    • The number of elements in the linked list is limited to the available memory space while the number of elements in the array is limited to the size of an array.

    If you are using C language to implement the heterogeneous linked list, what pointer type should be used?

    Best Answer
    Ask The Science

    The heterogeneous linked list contains different data types, so it is not possible to use ordinary pointers for this. For this purpose, you have to use a generic pointer type like void pointer because the void pointer is capable of storing a pointer to any type.
