                                                                           Time : 3 Hours

                                                                      Maximum Marks : 70

1. (a) What is the difference between Actual Parameter and Formal
Parameter? Give a suitable example to illustrate both in a C+ +
code.

(b) Name the header file(s), which are essentially required to run the following program segment:
void main( )
{
char A= ‘K’,B;
if (islower (A))
B = toupper(A);
else
B = ‘*’;
cout<<A<<” turned to “<<B<<endl;
}

(c) Find syntax error(s), if any, in the following program:
(Assuming all desired header file(s) are already included)
typedef String [80] char;
void main
{
String S;
for (L=0;L<26;C++)
S [L] = L + 65;
S[L]=’ \0’;
cout<<S<<endline;
}

(d) Give the output of the following program segment:
(Assuming all desired header file(s) are already included)
void main ( )
{
float *ptr, Points[]={20, 50, 30, 40, 10};
Ptr=Points;
cout<<* Ptr<<endl;
Ptr+=2;
Points [2]+ = 2 .5;
cout<<* Ptr<<endl;
Ptr++;
(*ptr) +=2.5;
cout<<Points [3] <<endi;
}

(e) Write the output of the following program:
*include <iostream.h>
class Quiz
{
int Round;float Score;
public:
Quiz() {Round=1;Score=0;}
Quiz(Quiz &Q) {Round=Q.Round+1;Score=Q.Score+10;}
void GetBonus(float B=5)
{
Score+=B;
}
void ShowScore()
{
cout<<Round<<” # “<<Score<<endl;
}
};
void main()
{
Quiz A;
A. ShowScore( );
A.GetBonus (10);
A.ShowScore();
Quiz B(A);
B.GetBonus();
B.ShowScore();
}
(f) Find out the expected correct output(s) from the options (i) to (iv) for the following C++ code. Also, find out the minimum and the maximum value that can be assigned to the variable Stop used in the code:
void main ( )
{
int Begin=3, Stop;
for (int Run=1;Run<4;Run++)
{
Stop = random (Begin) +6;
cout<<Begin++<<Stop<<”*”;
}
}

(i) 36*46*59*
(ii) 37*46*56*
(iii) 37 *48*57*
(iv) 35 *45* 57*
