i write following program but my program does not run and not given required output. please someone check this and correct this or write this in better form.thanks. program and coding is given below:
program:
Write a C++ program that has class
1) math
Math class has only one data member number and member function display that will display the data member number.
Write the constructor of your math class that will initialize the data member number with the value zero.
Program will overload the following operators.
1. Plus +
2. Minus -
3. Multiplication *
After overloading these three operators program will be able to add, subtract and multiply your math class object with the integer in main() after overloading these operators you should be able to write these statements in main().
math obj1, obj2;
obj1= obj2 + 10;
Above statement will call the member function operator + () and will add the 10 in the data member of obj2 and finally will return the math class object. Similarly you also overload the multiplication operator * and minus operator – so that your math class object will be able to multiply and subtract from integer values.
Also your plus + overloaded operator should be intelligent enough to accommodate the following statement in the main() function.
math obj1, obj2;
obj2= 10 + obj1;
for this you will have to write friend function that will be called automatically and will add the integer value 10 in the data member of obj1 and finally will return the math class object . Similarly write two more friend functions that will overload the multiplication and subtraction operator so that you will be able to write the following statement in the main() function.
math obj1, obj2;
obj2= 10 *obj1;
obj2= 10 - obj1;
Your output should be similar to the following:
Sample output 1:
adding integer 10 in the object using statement: obj= obj + 10 ;
10
adding integer 10 in the object using statement: obj= 10 + obj;
20
Multiplying object with integer 20 using statement: obj= obj * 20 ;
400
Multiplying integer 20 with object using statement: obj= 20 * obj ;
8000
Subtracting 20 from object using statement: obj= obj - 20 ;
7980
Subtracting object from 10 using statement: obj= 10 - obj ;
-7970
Code:
#include<iostream.h>
class mth
{
friend class number;
Public:
class math():
int (0){}
void print member (){
cout<<number<<endl;
}
operator float();
object add (+);
object sub(-);
object multi (*);
{
//The implementation is object:add,sub,multi,}
Private:
i=10;
};
//friend functions
friend float add both(class math,number class);
friend float sub both(class math,number class);
friend float multi both(class math,number class);
};
class number
{Private:
float value;
public:
number class()
{
value=10;
}
//friend functions
friend float add both(class math,number class);
friend float sub both(class math,number class);
friend float multi both(class math,number class);
};
void int main()
{
mth obj1,obj2;
obj1=obj2+10;
obj2=10+obj1;
obj2=10*obj1;
char choice;
cout<<"pleae enter one of the operator +,-,*:";
if (choice=='+')
{cout<<"adding integer 10 in the object using statement:";
if (choice=='+')
{cout<<"adding object 10 in the object using statement:";
if (choice=='*')
{cout<<"multi object 20 in the object using statement:";
if (choice=='*')
{cout<<"multi integer 20 in the object using statement:";
if (choice=='-')
{cout<<"sub 20 from the object using statement:";
if (choice=='-')
{cout<<"sub obj from 10 using statement:";
}
system("PAUSE");
getch();
