Operator overloading,operator tambah C++

Berikut ini adalah salah satu contoh program overloading operator tambah dalam bahasa C++.
#include<iostream.h>
#include<iostream.h>

class Buah
{
private:
int apel;
int jeruk;
public:
Buah(int jum_apel=0,int jum_jeruk=0);
void info_buah();
Buah operator+(Buah b2);
Buah operator+(int tambahan);
};
void main()
{
clrscr();
Buah buah1 (20,5);
Buah buah2;

cout<}
Buah Buah::operator+(Buah b2)
{
Buah tmp;
tmp.apel=apel+b2.apel;
tmp.jeruk=jeruk+b2.jeruk;
return(tmp);
}
Buah Buah::operator+(int tambahan)
{
Buah tmp;
tmp.apel=apel+tambahan;
tmp.jeruk=jeruk+tambahan;
return(tmp);

This Example Programs Calculate Prime Number Using Constructor

ALGORITHM:
STEP 1: Start the program.
STEP 2: Declare the class as Prime with data members,
Member functions.
STEP 3: Consider the argument constructor Prime() with integer
Argument.
STEP 4: To cal the function calculate() and do the following steps.
STEP 5: For i=2 to a/2 do
STEP 6: Check if a%i==0 then set k=0 and break.
STEP 7: Else set k value as 1.
STEP 8: Increment the value i as 1.
STEP 9: Check whether the k value is 1 or 0.
STEP 10:If it is 1 then display the value is a prime number.
STEP 11:Else display the value is not prime.
STEP 12:Stop the program.

C++ PROGRAM:
01#include<iostream.h>
02#include<conio.h>
03class prime
04{
05                int a,k,i;
06              public:
07              prime(int x)
08              {
09                            a=x;
10              }
11              void calculate()
12              {
13                 k=1;
14                {
15                     for(i=2;i<=a/2;i++)
16 
17       if(a%i==0)
18                     {
19                              k=0;
20                              break;
21                     }
22                     else
23                    {
24                            k=1;
25                  }
26                }
27              }
28 
29void show()
30              {
31                if(k==1)
32                  cout<< “\n\tA is prime Number. ";
33                else
34                  cout<<"\n\tA is Not prime.";
35              }
36};
37 
38void main()
39{
40    clrscr();
41    int a;
42    cout<<"\n\tEnter the Number:";
43    cin>>a;
44    prime obj(a);
45    obj.calculate();
46    obj.show();
47    getch();
48}

To calculate factorial of a given number using copy constructor.


ALGORITHM:
STEP 1: Start the program.
STEP 2: Declare the class name as Copy with data members and member functions.
STEP 3: The constructor Copy() with argument to assign the value.
STEP 4: To cal the function calculate() do the following steps.
STEP 5: For i=1 to var do
STEP 6: Calculate fact*i to assign to fact.
STEP 7: Increment the value as 1.
STEP 8: Return the value fact.
STEP 9: Print the result.
STEP 10: Stop the program.

PROGRAM:

01#include<iostream.h>
02#include<conio.h>
03class copy
04{
05              int var,fact;
06              public:
07 
08                copy(int temp)
09                {
10                 var = temp;
11                }
12 
13                double calculate()
14                {
15                            fact=1;
16                            for(int i=1;i<=var;i++)
17                            {
18                            fact = fact * i;
19                            }
20                            return fact;
21                }
22};
23void main()
24{
25    clrscr();
26    int n;
27    cout<<"\n\tEnter the Number : ";
28    cin>>n;
29    copy obj(n);
30    copy cpy=obj;
31    cout<<"\n\t"<<n<<" Factorial is:"<<obj.calculate();
32    cout<<"\n\t"<<n<<" Factorial is:"<<cpy.calculate();
33    getch();
34}
Output:
Enter the Number: 5
Factorial is: 120
Factorial is: 120

Perform exception handling for Divide by zero Exception

perform exception handling for Divide by zero Exception.
ALGORITHM:
Step 1: Start the program.
Step 2: Declare the variables a,b,c.
Step 3: Read the values a,b,c,.
Step 4: Inside the try block check the condition.
a. if(a-b!=0) then calculate the value of d and display.
b. otherwise throw the exception.
Step 5: Catch the exception and display the appropriate message.
Step 6: Stop the program.

PROGRAM:
01#include<iostream.h>
02#include<conio.h>
03void main()
04{
05   int a,b,c;
06   float  d;
07   clrscr();
08   cout<<"Enter the value of a:";
09   cin>>a;
10   cout<<"Enter the value of b:";
11   cin>>b;
12   cout<<"Enter the value of c:";
13   cin>>c;
14 
15   try
16   {

To perform exception handling with multiple catch.

ALGORITHM:
Step 1: Start the program.
Step 2: Declare and define the function test().
Step 3: Within the try block check whether the value is greater than zero or not.
a. if the value greater than zero throw the value and catch the corresponding exception.
b. Otherwise throw the character and catch the corresponding exception.
Step 4: Read the integer and character values for the function test().
Step 5: Stop the program.

PROGRAM:
01#include<iostream.h>
02#include<conio.h>
03void test(int x)
04{
05   try
06   {
07              if(x>0)
08                 throw x;
09        else
10                 throw 'x';
11   }
12
13   catch(int x)
14   {
15              cout<<"Catch a integer and that integer is:"<<x;
16   }
17
18   catch(char x)
19   {
20              cout<<"Catch a character and that character is:"<<x;
21   }
22}
23
24void main()

To find the mean value of a given number using friend function.

ALGORITHM:
STEP 1: Start the program.
STEP 2: Declare the class name as Base with data members and member functions.
STEP 3: The function get() is used to read the 2 inputs from the user.
STEP 4: Declare the friend function mean(base ob) inside the class.
STEP 5: Outside the class to define the friend function and do the following.
STEP 6: Return the mean value (ob.val1+ob.val2)/2 as a float.
STEP 7: Stop the program.

01#include<iostream.h>
02#include<conio.h>
03class  base
04{
05    int val1,val2;
06   public:
07    void get()
08    {
09       cout<<"Enter two values:";
10       cin>>val1>>val2;
11    }
12    friend float mean(base ob);
13};
14float mean(base ob)
15{
16   return float(ob.val1+ob.val2)/2;

34     cout<<”Enter your Choice:";
35     cin>>ch;
36 
37     switch(ch)
38     {

40                cout<<"Enter Radious of the Circle:";
41                cin>>r;
42                obj.area(r);
43                break;
44              case 2:
45                cout<<"Enter Sides of the Rectangle:";
