    C Array

    The array is a collection of components of the same data type, which can save a fixed-size consecutive element. For instance, if you wish to store 10 numbers, it is much easier to specify a variety of 10 sizes, instead of defining ten variables.

    Considering that ranges give a simple means to stand for data, it is identified among the information frameworks in C. Various other data frameworks in C are structure, checklists, queues, trees, etc. Variety can be utilized to represent not only a basic list of data however additionally a table of data in two or 3 measurements.

    In C programming, a variety can be One-dimensional, Two-dimensional, as well as Multi-dimensional.

    Features of Array
    1. An array holds components that have the same data type.
    2. Elements are kept in memory areas.
    3. Two-dimensional array elements are kept row by row in subsequent memory areas.
    4. Array name stands for the address of the starting element.
    5. Array size should be discussed in the affirmation. The Array size should be a consistent expression and not a variable.
    Declaring an Array

    This is called a one-dimensional array. An Array type can be any kind of legitimate C data type, as well as array size need to be an integer and more than zero.

    Syntax: data_type variable_name[size]

    Example: int arr[10];

    Here “int” is the data type, “arr” is the name and 10 is the size. It suggests given array can only have 10 elements of int type space. The index no. start from 0 to size-1 in the array which implies the first element stored in arr[0] and others are respectively follow.

    Initializing an Array

    After a declaration of an array, it has to be initialized. Or else, it will include garbage value( any arbitrary value). An array can be initialized at either put compiler time or at runtime.

    1. Compile-time Initialization:

      Compile-time initialization of the array is like regular variable initialization.

      Syntax: data_type array_name= {values}

      For Example:

      C Array
    2. Runtime Initialization:

      An array can likewise be initialized at runtime using scanf() function. This method is normally used for initializing up the large array, or to initialize arrays with user-specified values.

      Example:

      C Array
    Accessing Array Elements

    A component is accessed by indexing the range name. This is done by positioning the index of the component within square braces after the name of the array.

    Syntax: data_type variable_name= arr_name[index no.]

    Two-dimensional Array

    C language supports multidimensional selections additionally. The easiest type of a multidimensional array is the two-dimensional array. Both the row’s as well as column’s index begins from 0.

    Example: int arr [3] [4];

    A two-dimensional array can be taken into consideration as a table which will have x number of rows as well as y number of columns., where ‘arr’ is the name of the selection, as well as ‘i’ and ‘j’ are the subscripts that uniquely recognize each element in ‘arr’.

    Initializing Two-Dimensional Array

    Multidimensional Array may be initialized by specifying bracketed values for every row. The embedded dental braces, which suggest the designated row, are optional.

    Syntax: int a [i][j] = {x,y,z}, {p,q,r}, …….{m,n,o}

    Accessing Two-Dimensional Array Elements

    An element in a two-dimensional array is accessed by utilizing the subscripts, i.e., row index and column index of the range.

    Syntax: int var_name= arr_name[i][j];
