Collections of items stored at the contiguous memory. Arrays can store items of the same data type. 

Why we use arrays? 

We need to store multiple items and using variable it gets overridden. In order to retain the multiples items of the same data type we will use arrays. All the elements are stored in consecutive locations 



  Example: int, float, string , char Valid A int[60]- Size should be constant Example: int[60]={435,435,55,56} Access the data 
  Three types 1)One dimensional Array 2)Two-dimension 3)Multidimensional 


 Disadvantages: 
 1)Consumes memory as we are deciding the fixed amount of memory at the compile time. At run time you cannot exceed the size limit of array.
