What are the two basic operations that are often performed on arrays?

Array is a data structure, and the two basic operations usually performed on arrays are "search and modification".

An array is a collection of data elements of the same data type stored in a continuous storage space. Through the subscript (position number) of the array element, the storage address of the array element can be found, so that the array element can be accessed. The value of the array element. It is commonly used to implement sequential tables, usually including search and modification operations. However, it should be noted that the sequence list is a one-dimensional array, while multi-dimensional arrays are typical non-linear structures.

It is also worth explaining that the characteristics of arrays are:

1) The number of array elements is fixed. Once an array is defined, there will no longer be any increase or decrease in elements.

2) The data elements have the same type.

3) The subscript relationship of the array has upper and lower bound constraints and the subscripts are ordered.

Therefore, arrays generally do not perform insertion and deletion operations.
