Shared pointers: Shared pointers are used in managing the ownership of the dynamically allocated object. Shared pointers are used when there are one or more owners available for the objects that are allocated dynamically. Example: The below snippet illustrates the usage of the shared pointer that manages different object: //usage of the shared pointer for the object stu1 shared_ptr<Student> stu1(new Student ()); //usage of the shared pointer for the object stu2 shared_ptr<Student> stu2(new Student ("George", 95)); Explanation: In general in the above code, the execution is carried out by making two separate memory allocation: Allocate the control block Allocate memory for the object Student that needs to be managed. When making separate allocation could incur significant overhead problems, in order to avoid the above problem the make shared function is used to efficiently allocate the memory.

Program Plan Intro

Shared pointers:

Shared pointers are used in managing the ownership of the dynamically allocated object.

Shared pointers are used when there are one or more owners available for the objects that are allocated dynamically.

Example:

The below snippet illustrates the usage of the shared pointer that manages different object:

//usage of the shared pointer for the object stu1

shared_ptr<Student> stu1(new Student ());

//usage of the shared pointer for the object stu2

shared_ptr<Student> stu2(new Student ("George", 95));

Explanation:

In general in the above code, the execution is carried out by making two separate memory allocation:

Allocate the control block

Allocate memory for the object Student that needs to be managed.

When making separate allocation could incur significant overhead problems, in order to avoid the above problem the make shared function is used to efficiently allocate the memory.
