15.
Write the definition for a class called complex that has floating point data members for storing real and imaginary parts. The class has the following member functions: void set(float, float) to set the specified value in object void disp() to display complex number object complex sum(complex) to sum two complex numbers & return complex number
1. Write the definitions for each of the above member functions.
2. Write main function to create three complex number objects. Set the value in two objects and call sum() to calculate sum and assign it in third object. Display all complex numbers.
16.
Answer the questions (i) and (ii) after going through the following program: class Match
{ int Time; public:
Match() //Function 1

{
Time=0; cout<<”Match commences”<<endl;
} void Details() //Function 2
{ cout<<”Inter Section Basketball Match”<<end1;
}
Match(int Duration) //Function 3
{
Time=Duration; cout<<”Another Match begins now”<<endl;
}
Match(Match &M)
{
//Function 4
Time=M.Duration; cout<<”Like Previous Match ”<<endl;
} }; i) Which category of constructor - Function 4 belongs to and what is the purpose of using it? ii) Write statements that would call the member Functions 1 and 3
