Concept explainers

Class

Object Oriented Programming System (OOPs) is a programming model built on the perception of “objects” that contains data and methods. The major purpose of Object Oriented Programming is to increase the maintainability and flexibility of programs. Object Oriented Programming gets together data and its behavior (methods) in a single location (object) which makes it easier to understand.

Question

1) Convert the following Java code by using a function in C++, Python.
public class lab9{
public static void main(String [Jargs){
System.out.println(" 10 + 20 =" + calc(10,20,+));
System.out.println(" 10 * 20 = "+ calc( 10, 20, "*'));
System.out.println(" 10 - 20 = "+ calc( 10, 20, -));
System.out.println(" 10/ 20 ="+ calc( 10, 20, "));
}
public static int calc (int arg1, int arg2, char arg3) {
int total=0;
if (arg3 ='+)
total = argl + arg2;
if (arg3 ==*)
total = argl * arg2;
if (arg3 =='-')
total = argl - arg2;
if (arg3 == '")
total = argl / arg2;
return total; }
%3D
%3D
10 + 20
10 * 20
20
10 / 20
The output is
30
= 200
-10
10
-
2) Write your codes again in C++, Python by using total as a global variable. Don't return
total from the function and the output will be the same.
