• The number of elements to be stored in arrays should be known beforehand.
• An array is static.
• Insertion and deletion is quite difficult in an array.
• Allocating more memory than required leads to wastage of memory.

What is an array and what is it used for?

An array is a data structure, which can store a fixed-size collection of elements of the same data type. An array is used to store a collection of data, but it is often more useful to think of an array as a collection of variables of the same type.

What are the disadvantages of arrays *?

What are the disadvantages of arrays? Explanation: Arrays are of fixed size. If we insert elements less than the allocated size, unoccupied positions can’t be used again. Wastage will occur in memory.

What is an array explain about arrays?

An array is a data structure that contains a group of elements. Typically these elements are all of the same data type, such as an integer or string. Arrays are commonly used in computer programs to organize data so that a related set of values can be easily sorted or searched.

What are the advantages and disadvantages of arrays?

Arrays represent multiple data items of the same type using a single name. In arrays, the elements can be accessed randomly by using the index number. Arrays allocate memory in contiguous memory locations for all its elements. Hence there is no chance of extra memory being allocated in case of arrays.

• C doesn’t perform any array index bound checking.
