In a shallow copy, . the values of two or more pointers are copied into a list two or more pointers of the same type point to the same memory location two or more pointers of differing types point to the same memory location two or more pointers of the same type point to different memory locations

Explanation:

A Shallow copy is a bit-wise (unit of data) copy of an object that can be found/used in an object-oriented programming language code, the copy contains all of the same exact values that exist within the original object. In a shallow copy, two or more pointers of the same type point to the same memory location.

two or more pointers of the same type point to the same memory

Explanation:

A shallow copy is a bit wise copy of another object. in this practice a new exact copy of an original object is created also if any of the fields of the original object is referenced to another object, while creating the shallow copy only the memory address of that field is copied.

A shallow copy is used in object oriented programming languages like C++, Java, python, SQL   etc A shallow copy is very efficient because it helps to create copies of already created objects instead of having to create new objects everything .
