Assignment 8: Structure

Structure
[SET – 1]

1	Give the output of the following program #include<iostream.h> struct Pixel  {             int C,R; }; void Display(Pixel P) {             cout<<"Col”<<P.C<<"Row"<<P.R<<endl; } void main() {             Pixel X={40,50},Y,Z;             Z=X;             X.C+=10;             Y=Z;             Y.C+=10;             Y.R+=20;             Z.C-=15;             Display(X);             Display(Y);             Display(Z); }
2	Find the output of the following program: #include <iostream.h> struct PLAY {             int Score, Bonus; }; void Calculate(PLAY &P, int N=10) {             P.Score++;             P.Bonus+=N; } void main() {             PLAY PL={10,15};             Calculate(PL,5);             cout<<PL.Score<<”:”<<PL.Bonus<<endl;             Calculate(PL);             cout<<PL.Score<<”:”<<PL.Bonus<<endl;             Calculate(PL,15);             cout<<PL.Score<<”:”<<PL.Bonus<<endl; }
3	Find the output of the following program: #include<iostream.h> struct MyBox {             int Length, Breadth, Height; }; void Dimension (MyBox M) {             cout<<M.Length<<"x"<<M.Breadth<<"x";             cout<<M.Height<<endl; } void main () {             MyBox B1={10,15,5}, B2, B3;             ++B1.Height;             Dimension(B1);             B3 = B1;             ++B3.Length;             B3.Breadth++;             Dimension(B3);             B2 = B3;             B2.Height+=5;             B2.Length--;             Dimension(B2); }
4	Rewrite the following program after removing the syntactical errors (if any). Underline each correction.  #include <iostream.h> struct Pixels {              int Color, Style; } void ShowPoint(Pixels P) {             cout<<P.Color,P.Style<<endl; }  void main() {              Pixels Point1=(5,3);              ShowPoint(Point1);              Pixels Point2=Point1;              Color.Point1+=2;              ShowPoint(Point2); }
5	Declare a structure to represent a complex number (a number having a real part and imaginary part). Write C++ functions to add, subtract, multiply and divide two complex numbers.
6	An array stores details of 25 students (rollno, name, marks in three subject). Write a program to create such an array and print out a list of students who have failed in more than one subject.
