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

Consider the following C++ code:
int n
= 1; // global
print1 (int x) {
cout << x + n;
}
plus_n () {
n = n + 2;
print1 (n);
}
main () {
int n;
n = 20;
print1 (5);
n = 40;
plus_n ();
cout << n;
What is the output of the program under?
c. Dynamic scoping rules
