Today We Run a program to find Area of a Rectangular Ground in c++ by class and object.
This c++ language programming is free all type of errors like the compiler and runtime errors and this programming is tested to compile and then run the program code.
Here is only programming code with the output. This programming output is customized to understand easily.
How to find the area of a rectangular ground in c++ programming?
#include <cmath>
using namespace std;
class Rect_Ground{
public:
double l, w;
void area(double l, double w) {
double result;
result = l * w;
cout<<“The area of the box: “<<result<<” squre unit”<<endl;
}
};
int main() {
Rect_Ground R;
cout << “enter the value of length: “;
cin >> R.l;
cout << “enter the value of width: “;
cin >> R.w;
B1.volume(R.l, R.w);
return 0;
}
enter the value of width: 10
The area of the Rectangular Ground:150 square unit;
‘result= (22/7)*r*r
where r is the radius and 22/7 use as Pie Value
