Question 6 :
Why do we Use a Multidimensional Array?
A multidimensional array can be useful to organize subgroups of data within an array. In addition to organizing data stored in elements of an array, a multidimensional array can store memory addresses of data in a pointer array and an array of pointers.
Multidimensional arrays are used to store information in a matrix form.
e.g. a railway timetable, schedule cannot be stored as a single dimensional array.
One can use a 3-D array for storing height, width and length of each room on each floor of a building.
Question 7 :
How do you assign an address to an element of a pointer array ?
We can assign a memory address to an element of a pointer array by using the address operator, which is the ampersand (&), in an assignment statement such as ptemployee = &projects;
Question 8 :
Run Time Memory Allocation is known as ?
Allocating memory at runtime is called a dynamically allocating memory. In this, you dynamically allocate memory by using the new operator when declaring the array, for example : int grades = new int;
Question 9 :
What method is used to place a value onto the top of a stack?
push() method, Push is the direction that data is being added to the stack. push() member method places a value onto the top of a stack.
Question 10 :
What method removes the value from the top of a stack?
The pop() member method removes the value from the top of a stack, which is then returned by the pop() member method to the statement that calls the pop() member method.
