like contains. C arrays are made up of primitives. A C array can be viewed as a contiguous memory block. The size of the block depends on the type of the array. For example, if we declare char A[10]; an array of 10 characters would require 10 bytes of storage for data. On the other hand, int A[10]; would require 10*sizeof(int) amount of storage.

A dynamic array is used where we come to know about the size on run time. Dynamic arrays is a popular name given to a series of bytes allocated on the heap. char *ptr = (char*) malloc(10); allocates a memory of 10 bytes on heap and we have taken the starting

A C++ DYNAMIC ARRAY C++ does not have a dynamic array inbuilt, although it does have a template in the Standard Template Library called vector which does the same thing. Here we define a dynamic array as a class, first to store integers only, and then as a template to store values of any type.

An array constructor is just a function accepting scalar or array arguments and returning an array result. The array constructor function array(A,B,C,...), with short-hand notation {A, B, C, ...}, constructs an array from its arguments {1,2,3} // A 3-vector of type Integer[3] array(1.0,2.0,3) // A 3-vector of type Real[3]

To declare an array in C, a programmer specifies the type of the elements and the number of elements required by an array as follows: type arrayName [ arraySize ]; This is called a single-dimensional array. The arraySize must be an integer constant greater than zero and type can be any valid C data type. For example, to declare a 10-element ...
