Answer:
Following are the solution to this question:
Explanation:
In this question, two packages "pkg1 and pkg2" is defined, that hold a class that is "MyClass", in which the class name is the same. If we import the package so, it can't import both classes in the very same file. If we really need to apply to both, then must completely specify one class name, and in the class name is different so, we simply use both classes by creating the instance.
Answer:
float diameter=2*r; //hold the diameter of a circle
float PI; // float variable named PI.
Explanation:
Here we have declared two variable i.e diameter and PI of type float. The variable diameter will hold the diameter of a circle i.e 2*r where r is the radius of a circle.
Following are the program in c++
#include <iostream> // header file
using namespace std; // namespace
int main() // main function
{
float r=9.2; // variable declaration
float diameter=2*r; //hold the diameter of a circle
float PI=3.14; // float variable named PI hold 3.14
cout<<"diameter IS :"<<diameter<<endl<<"PI IS :"<<PI; // display value
return 0;
}
Output:
diameter IS :18.4
PI IS :3.14
