Show the output of the following code: #include <iostream>using namespace std;const double PI = 3.14159; double getArea(double radius){return radius * radius * PI; }void displayArea(double radius) {cout << getArea(radius) << end1; }int main() {double r1 = 1; double r2 = 10;cout << getArea(r1) << end1; displayArea(r2);}
OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.
Constructor
The easiest way to think of a constructor in object-oriented programming (OOP) languages is:
Show the output of the following code:
#include <iostream>
using namespace std;
const double PI = 3.14159; double getArea(double radius)
{
return radius * radius * PI;
}
void displayArea(double radius)
{
cout << getArea(radius) << end1;
}
int main()
{
double r1 = 1; double r2 = 10;
cout << getArea(r1) << end1; displayArea(r2);
}
