/* Create two classes DM and DB which store the values of distance. DM stores distance in meters and centimeters. DB stores distances in feet and inches. Write a program that can read values for the class object and add one object of DM with another object of DB. Use a friend function to carry out the addition operation and this function will display answer in meter and centimeters. / #include<iostream.h> #include<conio.h> class DM; class DB { float f,inch; public: DB(){} DB(float a,float b) { f=a; inch=b; } void putdata() { cout<<"\nFEET:"<<f<<", INCH:"<<inch; } float getf() { return f; } float getInch() { return inch; } }; class DM { float m,cm; public: DM(){} DM(float a,float b) { m=a; cm=b; } void putdata() { cout<<"\nM="<<m<<", CM="<<cm<<endl; } friend DM operator+(DM &t1,DB &t2) { DM t3; DM temp = t2; t3.m = t1.m + temp.m; t3.cm = t1.cm + temp.cm; return t3; } DM(DB & t1) { float t=t1.getf()30; t+=t1.getInch()*30/12; m=t/100; cm=(int)t%100; } }; int main() { DM o1(5,6); DB o2(3,4); DM o3 = o1 + o2; o3.putdata(); getch(); return 0; }


Input Values(You must enter all user input value here, that you want to use during runtime)



To Run C++ Program 1. #include<iostream.h> change to #include<iostream> 2. #include<math.h> change to #include<cmath>; 3. #include<string.h> change to #include<cstring>; 4. Add line using namespace std; These all(1 to 4) will be done automatically..., So don't worry.
