POST TEST :

Question 1:
For constructor overloading, each constructor must differ in ___________ and __________

Number of arguments and type of arguments
Number of arguments and return type

Question 2:
Which among the following is correct for the class defined below?
class student{
int marks;
public: student(){}
student(int x){
marks=x;
}
};
main(){
student s1(100);
student s2();
student s3=100;
return 0;

Object s3, syntax error
Only object s1 and s2 will be created
Program runs and all objects are created
Program will give compile time error

---

Question 3:
Which object will be created first?
class student {
int marks;
};
student s1, s2, s3;

s1 then s2 then s3
s3 then s2 then s1
s2 then s3 then s1
none of the above
