Consider the following two combinations of class and function in C++.
1. Explain the difference in using the function addi as the user of the classes would see it. Give sample code for the two cases, including object creation.
2. If the declaration of i in the two classes is changed from public to private, what will happen a) at compile-time, and b) at run-time?
3. Explain the difference at run-time if the declaration of the parameter x in global function addi is changed to example1 x.
class example1 {
public:
int i;
};
int addi(example1 &x, int j) {
x.i = x.i + j;
return x.i;
}
class example2 {
public:
int i;
int addi(int j) {
i = i + j;
return i;
}
};
