Hi,i have a problem with this code ,it aborts but i don't know why,can any 1 help me?


#include #include #include #include #include using namespace std; class year { public: int y; vector month ; vector day ; year(int YE,vector* M,vector* D): y(YE) { M = new vector(12) ; D = new vector(12) ; } year() {}; }; void main(){ year Y; cin>>Y.y ; if(Y.y==1992) Y.month[3]=8; else Y.month[3]=9; cout< 14 years ago

Hi! In the year class you have 2 constructors, when you create object "Y" with the statement
year Y;
the second constructor is called (the one that does nothing). So neither of "month" or "day" is constructed properly. When you access to "month" or "day", it will give unexpected results.

I believe that the 2nd constructor was actually a destructor, you just forgot the "~" before it :) . Also, in the first contructor, you only initialized y, you did nothing to "month" and "day". Anyway, here is my code for the year class:
class year {
public:
int y;
vector<int> month ;
vector<int> day ;
year(){
y = 0;
month = vector<int>(12);
day = vector<int>(12);
}
~year() { };
};
I hope it helps! :)
