Use only C++ for all function

Introduce a call-by-value function that computes the volume of a box. Hint: Length, width, and height of a box is needed.

Introduce a call-by-reference function with void output. that computes the square of an integer. Please double check the value of the function input before and after function call.

Introduce a call-by-pointer function with void output. that computes the square of an integer. Please double check the value of the function input before and after function call.

Introduce an integer vector. Then introduce a function to reverse this vector. (Do not use reverse library provided by C++.

Introduce an integer vector. Then introduce a function to check whether this vector is palindrome. If yes, please return true. If not, please return false.

Read the following code and see whether you can interpret/understand the results. Copy the code to your IDE. Use debugger to see the if the result is the same as your interpreted results. int a = 5; //assume that a is located at 1000. as pointer is located at 5000

int &b = a; a = 10;

cout<<&b<

int *c = &b;

cout<

int** cPtrPtr = &c;

cout<<*c<

cout<

int d = 20; int* dPtr = &d;

int** dPtrPtr = &dPtr;

dPtr= *cPtrPtr;

cout<<*dPtr<

cout<

cout <

Introduce a main function that calls all the functions above
