Question(2) : [ 10 Marks]
A) Write a structure specification that includes three variables—all of type int—called hrs, mins, and
secs. Call this structure time. [ 2 marks ]
Answer:
struct time
{ int hrs;
int mins;
int secs;
};
B) Write statements that define a variable time2 structure and set the hrs member variable equal to 17
, mins to . 30 , and secs to 10.
[ 2 marks]
time time2;
Another Answer:
time2hrs= 17;
time2mins= 30;
time2secs= 10;
int main(void)
time time2={ 17, 30, 10 };
C) Compute and Print out the total number of seconds represented by this time2 value: Totalsecs =
hours*3600 + minutes*60 + seconds.
[ 2 marks]
Answer:
int main(void)
time time2={ 17, 30, 10};
int Totalsecs = time2hrs* 3600+ time2mins*60 + time2secs;
D) Write a statement that declares an enumeration called Players with the values
Back_defender=5, Back_Left=10, Back_right, and Striker.
[ 2 marks]
Keeper=1,
Answer:
enum Players { Keeper=1, Back_defender=5, Back_Left=10, Back_right, Striker };
E) Define two variables Elshamrany and Eldeaae of enumeration Players and assign them the
values Striker and Keeper, respectively?
[2 marks]
Answer:
Players Elshamrany = Striker , Eldeaae = Keeper ;

Question(3) : 3.A) Write the outputs of executing this program
[ 5 Marks]
#include <iostream>
using namespace std;
void order(int&, int&);
int main()
{
int n1=99, n2=11;
int n3=22, n4=88;
order(n1, n2);
order(n3, n4);
cout << “n1=” << n1 << endl; //print out all numbers
cout << “n2=” << n2 << endl;
cout << “n3=” << n3 << endl;
cout << “n4=” << n4 << endl;
return 0;
}
//-------------------------------------------------------------void order(int& numb1, int& numb2)
{
if(numb1 > numb2)
{
int temp = numb1;
numb1 = numb2;
numb2 = temp;
}
}
The outputs are:
n1 = 11
n2 = 99
n3 = 88
n4 = 22

3.B) Write the outputs of executing this program
[ 5 Marks]
#include <iostream>
using namespace std;
float getavg(float);
int main()
{
float data=1, avg;
while( data != 0 )
{
cout << “Enter a number: “;
cin >> data;
avg = getavg(data);
cout << “New average is “ << avg << endl;
}
return 0;
}
//-------------------------------------------------------------float getavg(float newdata)
{
static float total = 0; //static variables are initialized
static int count = 0; // only once per program
count++; //increment count
total += newdata; //add new data to total
return total / count;
}
The outputs are:
Enter a number: 10
New average is 10
total is 10, count is 1
Enter a number: 20
New average is 15
total is 30, count is 2
Enter a number: 30
New average is 20
total is 60, count is 3
When Enter a number: 0
Exit from program

Question(4) : [ 10 Marks]
A) Create a class called Employee that contains two variables a name (an object of class string) and an
employee ID (type long). Include a two public member functions called getdata() to get data from the
user for insertion into the object, and another function called putdata() to display the data.
[ 3 marks]
class Employee
{ private:
string name;
long ID;
Public:
void getdata(void) ;
void putdata(void) ;
};
B) Define the public function void getdata() outside class definition to get data from the user
for insertion into the object?
[2 marks]
void Employee :: getdata(void)
{ cout<< "enter Employee name:";
cin>> name;
cout<< "enter Employee ID:";
cin>> ID;
}
8
C) Define the public function void putdata() to display the data?
[ 2 marks]
void Employee :: putdata(void)
{
cout<< " Employee name is "<< name;
cout<< "Employee ID is
" << ID;
}
D) Write a main() program to exercise this class. It should create an object of type Employee, and call
functions getdata() and putdata() for this object?
[ 3 marks]
#include<iostream>
int main(void)
{
Employee e1, e2,e3 ;
e1.getdata();
e1.putdata(); cout<<endl;
e2.getdata();
e2.putdata(); cout<<endl;
e3.getdata();
e3.putdata(); cout<<endl;
system("PAUSE");
return 0;
}
