Give a suitable example using a C++ code to illustrate the same. 2EQ1. a) Write short notes on typedef and #define. 2b) Give the Header files to run the following code. 1void main(){cout<<”Click 2 Win”;cout<<setw(9)<<”hello”;}c) Find the Errors in the following program code and rewrite the correct code. 2Include<iostream.h>class bank{int acno;char nm[20];float balamt;void bank(){ }void input(){cout<<”Enter the acno “;cin>>acno;}}void Main(){bank b;input.b();}d) Find the output of the following program: 3 #include<iostream.h> void main() { int X[]={30,35,50,66,110}; int *p=X; while(*p<110) { if(*p%3!=0) *p=*p+1; else *p=*p+2;p++;}for(int I=4;I>=1;i--){cout<<X[I]<<”*”;if(I%3==0) cout<<endl;

}cout<<X[0]*3<<endl; }e) Find the output of the following program 2

#include<iostream.h> #include <ctype.h> void CangeIt (char Text[], char C) {for (int K=0;Text [K]!='\0' ;K++) { if (Text[K] >='F' && Text[K] <='L')

Text[K]=C; else if (K%2==0)

Text[K]=toupper(Text[K]);else

Text[K]=Text[K-1];} }

ChangeIt (oldText,'%'); cout <<"New TEXT:"<<oldText<<endl; }

f) The following code is from a game .which generates a set of 4random numbers :identify the correct option(s)out of the four choices given below as the possible set of such numbers generated from the program code so that he wins the game. Justify your answer. 2

#include <iostream.h> #include <stdio.h> const int LOW = 15 ; void main( ) { randomize( ) ;

int POINT =5, Number ; for (int I = 1 ; I <= 4 ; I ++) { Number = LOW + random(POINT) ;

cout << Number << “:” ; POINT-- ;

} }

class TEST { int Regno, Max, Min, Score ; public :

TEST( ){ //Function 1 Regno = 101 ; Max=100; Min = 40 ; score = 75 ;

}TEST(int Pregno, int Pscore) //Function 2{Regno = Pregno ;

Max = 100 ; Min = 40 ; Score = Pscore ;

}~TEST( ) //Function 3

{cout << “TEST Over” << endl ;}void Display( ) //Function 4{

cout << Regno << “:” <<Max<< “:” << Min << endl ; cout << “[Score]” << Score << endl; } } ;

(i) What type of function 4 is and how it will be invoked(ii) What is Function 3 specifically referred as ? When do you think, Function 3 will be invoked/called?
