Design,develop,and execute a program in C++ to create a class called OCTAL, which has the characteristics of an octal number, Implement the following operations by writing an appropriate constructor and an overloaded operator +.
<![if !supportLists]>1. <![endif]>OCTAL h=x;where x is an integer
<![if !supportLists]>2. <![endif]>Int y=h+k; where h is an OCTAL object and k is an integer.
Display the OCTAL result by overloading the operator<<. Also display the values of h and y.
#include<iostream.h>
#include<conio.h>
class octal
{
int onum;
public:
octal(int);
friend ostream& operator<<(ostream&,octal&);
int operator+(int);
};
octal::octal(int x)
{
//decimal to octal conversion
int base=1,rem;
onum=0;
while(x>0)
{
rem=x%8;
x=x/8;
onum=onum+rem*base;
base=base*10;
}
}
ostream& operator<<(ostream& dout,octal& h)
{
dout<<h.onum;
return dout;
}
octal::operator+(int k)
{
//conversion from octal to conversion
int rem,base=1,dnum=0,y;
while(onum>0)
{
rem=onum%10;
onum=onum/10;
dnum=dnum+rem*base;
base=base*8;
y=dnum+k;
}
return(y);
}
void main()
{
int x,k,y;
clrscr();
cout<<"enter the value of x \n";
cin>>x;
octal h=x;
cout<<"the value of h is"<<h<<endl;
cout<<"enter the value of k \n";
cin>>k;
y=h+k;
cout<<"value of y="<<y;
getch();
}
