【类和对象】初始化列表构造函数

相当于构造函数的另一种方便的写法

#include<iostream>
#include<cstdio>
using namespace std;
class T{
	public:
		int s_a;
		int s_b;
		int s_c;
	public:
		T(int a, int b, int c): s_a(a), s_b(b), s_c(c){
		}
};
void f()
{
	T t1 = T(10,20,30); 
	cout<<t1.s_a<<" "<<t1.s_b<<" "<<t1.s_c<<endl;
}
int main()
{
	f();
	return 0;	
}
