Write a c plus plus program to create a class float that contain one float data member overload all 4 arithmetic operator so that they operate an the object float?

Answer 1

/ circarea.cpp // demonstrates floating point variables #include <iostream> //for cout, etc. using namespace std; int main() { float rad; //variable of type float const float PI = 3.14159F; //type const float cout << "Enter radius of circle: "; //prompt cin >> rad; //get radius float area = PI * rad * rad; //find area cout << "Area is " << area << endl; //display answer return 0; } */ void main(void) { cout<<"### Programmed By Amahdy(MrJava) ,right restricted.\n"; cout<<"-------------------------------------------------------------------------------\n"<<endl; float rad; do{ cout<<"Enter radius of circle: "; cin>> rad; cout <<"Area is "<<circarea(rad); cout<<"\n\n !Press c to continue or any key to exit."<<endl<<endl; }while(getch()=='c'); } float circarea(float radius) { return 3.14159F*radius*radius;} Code:

/**2. Raising a number n to a power p is the same as multiplying n by itself p times. Write a function called power() that takes a double value for n and an int value for p, and returns the result as a double value. Use a default argument of 2 for p, so that if this argument is omitted, the number n will be squared. Write a main() function that gets values from the user to test this function.*/ #include<iostream> #include<conio.h> using namespace std; double power(double n, int p=2); void main(void) { cout<<"### Programmed By Amahdy(MrJava) ,right restricted.\n"; cout<<"-------------------------------------------------------------------------------\n"<<endl; double n; int p=2; do{ cout<<"Enter n: "; cin>> n; cout<<"Enter p: "; cin>> p; cout <<"The power is "<<power(n, p); cout<<"\n\n !Press c to continue or any key to exit."<<endl<<endl; }while(getch()=='c'); } double power(double n, int p){ for(int ret=1; p>0; p--) ret*=n; return ret;}

Code:

/**3. Write a function called zeroSmaller() that is passed two int arguments by reference and then sets the smaller of the two numbers to 0. Write a main() program to exercise this function.*/ #include<iostream> #include<conio.h> using namespace std; bool zeroSmaller(int& n1, int& n2); void main(void) { cout<<"### Programmed By Amahdy(MrJava) ,right restricted.\n"; cout<<"-------------------------------------------------------------------------------\n"<<endl; int n1, n2;
