Arrays in C++ tutorials

  • A Variable store only one value.

  • Where is Array helps to store several value of same data type under single variable name.

  • An array is a set of related data items i.e. all of them belong to the same data type and can be accessed by a common name.

  • An array is a derived data type.

  • An array in C++ Programming Language can be defined as number of memory locations, each of which can store the same data type and which can be references through the same variable name.

  • Thus an array is a collection of similar elements. These similar elements could be all integers, all floats or all characters etc.

  • Usually, the array of characters is called a string, where as an array of integers or floats is called simply an array. Remember that all elements of any given array must be of the same data type.

  • Instead of declaring 10 individual variables such as int no0,no1,no2,no3. no9; we can simply say int no[10];

  • This is an example of an array of ten integers, the name of the array variable is no and the size is ten, and all the elements are of type integer.

  • Each element of an array is stored in adjacent locations of the memory.

  • The lowest address corresponds to the first element and the highest address of array will be last element.

  • The size given in square brackets has to be constantan index also called as a subscript is used, in square brackets following the name of the array, to uniquely identify a particular element.

  • This subscript can be in the range of zero to one less the size of the array.

  • Array can be Single Dimensional, Double Dimensional or Mutli-dimensional.


Declaring Single Dimensional Array


Datatype arrayName [ Size ]; // Single Dimensional Array

Datatype arrayName [ Size ] [Size]; // Double Dimensional Array

Datatype arrayName [ Size ] [Size] [Size ]; // Three Dimensional Array


For Example:


























  • no[0] refers to the first element in the array.

  • no[1] refers to the second element in the array.

  • no[9] refers to the last element in the array.


Array initialization

  • All elements in an array variable cannot be initialized automatically.

  • Each element of an array has to be initialized separately, either in the declaration statement or using loop.


int no[5]={20,30,25,23,21}; or


int no[ ] = {20,30,25,23,21}; or

int no[5];
