The Area of a Circle = pi *(r*r). Where pi=3.1415 and r=Radius, Make a program that will

input Radius and compute and display the Area. Your program will be terminated if input zero

in the radius.

Make a program that will input Dollar currency, convert it into peso. Peso= dollar

currency*50.00 pesos, Display the peso equivalent. Your program will be terminated if the

inputted Dollar currency = 0.

Create class Student which contains database of rollNo, name, height, weight & percentage using

constructor and also display this database of 3 student using a method called display(). Then destroy the

objects when they are no longer needed.

Q#4). Create a class called Stack for storing integers. The data members are an integer array for storing

the integers and an integer for storing the top of stack (tos). Include member functions for initializing tos

to 0, pushing an element to the stack and for popping an element from the stack. The push() function

should check for “stack overflow” and pop() should check for “stack underflow”.

1.     Make a program that will input type of accommodation room. A-for first class, B-for second class. Charge as follows : first class=800.00 and second class = 650.00. Your program will be terminated if you input C in the accommodation room type.

the parameter list.

2. A function prototype in C++ has a local scope as it is only

accessible within the main or the function where they are

declared in.

3. By default all parameters are declared as integer values.
