Question

Given this code defining a class (shown with line numbers):

1: class newClass {
2: private:
3: int a;
4: public:
5: void setA(int value) { a = value; }
6: int getA() { return a; }
7: newClass(int value) : a(value) {};
8: newClass() { a = 0; }
9: };

Which of the following snippets of code, when written in main() where the class above has been defined, will cause a syntax error when compiled?

		newClass something; something.setA(8);
		newClass something; something.setA(8); int x = something.getA();
		newClass something; something.a = 8;
		newClass something(17);

Answer 1

Option3

newClass something;
something.a = 8;

Explanation:

The Error In the above code occurs due to the following reason.

a is a private member of class and hence can't be accessed directly using an object
