Construct the class Complex that has floating point data members for storing real and imaginary parts and perform complex number subtraction using operator Overloading.

he class Complex has the following member functions:

Complex() - Null constructor invokes when an object is created

Complex(float, float) - Parameterized constructor to set the specified value of real and imaginary parts in object

Operator()- To subtract an object from another object

print() - Function to display complex number object

Test Case: 1

INPUT:

R1:15

I1: 2

R2: 5

I2: 10

OUTPUT:

A =15 + i2

B = 5 + i10

C = 10 + i(-8)

Design a C++ program having a base class Student with data member rollno and member functions getnum() to input rollno and putnum() to display rollno. The class Test is derived from class Student with data member marks and member functions getmarks() to input marks and putmarks() to display marks. The class Sports is also derived from class Student with data member score and member functions getscore() to input score and putscore() to display score. The class Result is inherited from two base classes, class Test and class Sports with data member total and a member function display() to display rollno, marks, score and the total (marks + score).

Testcase:

INPUT:

OUTPUT:

Roll no:2

Mark1:80

Mark2:80

Mark3:80

Write a program that reads all the match outcomes and summarizes the information of all the matches.

Points are given to the teams based on the outcome of the match.

A win earns a team 3 points. A draw earns 1. A loss earns 0.

The following information is expected:

MP: Matches Played

W: Matches Won

D: Matches Drawn (Tied)

L: Matches Lost

P: Points

The team information should be displayed in descending order of points.

Input

The input will be a single line containing a string.
Output

The output should contain the sum and average of the digits of all numbers that appear in the string.
 Note: Round the average value to two decimal places.
Explanation

For example, if the given string is "I am 25 years and 10 months old", the digits of all numbers that appear in the string are 2, 5, 1, 0. Your code should print the sum of all digits(8) and the average of all digits(2.0) in the new line.
