如何给自定义的类的数组赋给初始值

[liztac]

我想给Activity act[100]的前11项赋给初始值，但是报错，请大侠指点一下应该怎么做。

#include <iostream>
#include <algorithm>
using namespace std;

struct Activity
{
int s; //start time
int f; //finish time
};

bool cmp(Activity A,Activity B)
{
return A.f<B.f;
}

int main()
{
Activity act[100]={Activity(1,4),Activity(3,5),Activity(0,6),Activity(5,7),Activity(3,9),Activity(5,9),Activity(6,10),Activity(8,11),Activity(8,12),Activity(2,14),Activity(12,16)};

struct Activity  
{  
	int s; //start time   
	int f; //finish time   
	Activity(int _s,int _f)
	{
		s=_s;
		f=_f;
	}
	Activity(){}
};
