PRACTICAL LIST
1
Write a C++ program that will print output in the following form. Make sure your output looks exactly as shown here (including spacing, line breaks, punctuation, and the title and author). Use cout and cin objects and endl manipulator.

Question: Difference between \n and endl.
2 Write a program to create the following table. Use endl and setw manipulator.

3
Write a C++ program to add two floating numbers using pointer. The result should contain only two digits after the decimal. Use fixed, scientific and setprecision () manipulators for controlling the precision of floating point numbers.
4 Write a C++ program to find out sum of array element using Recursion.
Question: Show stepwise solution of winding and unwinding phase of recursion
5 Find error in the following code and give reasons for each error: Can we declare an array of references? Can we assign NULL value to reference variable? Is Reference variable a pointer variable? Can we declare a reference variable without initializing it? Does Reference Variable change the original value of variable?
6 Find output of the following code: Explain how scope Resolution operator is used to access global version of a variable.
7 Write a program to enter a size of array. Create an array of size given by user using “new” Dynamic memory management operator (free store operator). Enter the data to store in array and display the data after adding 2 to each element in the array. Delete the array by using “delete” memory management operator.
8 Find Error in the following code of a program and give explanation why these errors exist. NOTE: USE reference of other material as there is a mistake in 6th edition of Bala Guruswamy.
9 Find the output of following program. Explain the use of bool data type.
Function
10 Define three functions named divide(). First function takes numerator and denominator as an input argument and checks it’s divisible or not, Second function takes one int number as input argument and checks whether the number is prime or not and Third function takes 3 float number as argument and finds out average of the numbers. Use concept of Function Overloading / static binding.
11 Write a function called tonLarge() that takes two integer arguments call by reference and then sets the larger of the two numbers to 100 using Return by reference. Write a main() program to exercise this function.
12 Write a function called power () that takes two arguments: a double value for n and an int for p, and returns the result as double value. Use default argument of 2 for p, so that if this argument is omitted, the number will be squared. Write a main () function that gets values from the user to test this function.
13 Define a C++ Structure Rectangle with data member’s width and height. It has get_values() member functions to get the data from user and area() member functions to print the area of rectangle. Also create a C++ Class for the above program. Define both functions inside the class. Member function defined inside the class behaves like an inline function and illustrate the difference between C++ Structure and C++ Class.
14 Write a C++ program having class Batsman. It has private data members: batsman name, bcode (4 Digit Code Number), innings, not out, runs, batting average. Innings, not out and runs are in integer and batting average is in float.Define following function outside the class using scope resolution operator.
1) Public member function getdata()to read values of data members.
2) Public member function putdata()to display values of data members.
3) Private member function calcavg() which calculates the batting average of a batsman. Also make this outside function inline.
Hint : batting average = runs/(innings - notout)

The second member function should add two objects of type currency passed as arguments such that it supports c3.add(c1,c2); where c1, c2 and c3 are objects of class Currency. Also Validate your answer if paisa >100. Write a main( )program to test all the functions. Use concepts of Object as Function Arguments, function returning object and function overloading.
16 Define a class Dist with int feet and float inches. Define member function that displays distance in 1’-2.5” format. Also define member function scale ( ) function that takes object by reference and scale factor in float as an input argument. The function will scale the distance accordingly.
