The idea behind inline functions is to insert the code of a called function at the point where the function is called. If done carefully, this can improve the application's performance in exchange for increased compile time and possibly (but not always) an increase in the size of the generated binary executables.

An Inline function is a function that is expanded in line when it is invoked. That is compiler replaces the function call with the corresponding function code.. :)

An inline function is a function where a copy of the logic is embedded in the application at each the point where it is called by the compiler. This basically allows a reduced overhead in function dereferencing

Delete: is used to deallocate memory from the heap that is created by new.

When you call delete, it firstly call the destructor of that object and then deallocate memory from heap.

class A

};

int
main()

A *a = new A();
delete a;

A *arr = new A[10];
delete []arr;
