1. "assigning" - don't use this word, it should be
initializing an object using another object of same type
2. When the object is passed to function - "by value"
3. when a function returns the object type - "by value"
here doesn't matter if you are assigning that returned
value to to another object or not.

Answer / vikas sood
hi fellows..try this code
class A {
public:
A() { }
A(const A& rhs)
{
cout<<"inside copy constructor..";
}
};
int main()
{
std::vector<A> aVec(10);
}
The answer to this is another reason a copy constructor
will be called.

Write a program to read the data and evaluate the results of the election. Print all output to the screen. Your output should specify: The total number of votes, the number of valid votes and the number of spoilt votes. The winner(s) of the election. Hint: An appropriate search should be used to determine the winner(s). The votes obtained by each candidate sorted in terms of the number of votes obtained. Hint: An appropriate sort should be used to sort the candidate(s). The Source code should be saved as VotingSystem.
