这几行代码是哪里出错了

[Shu_a]

#include<iostream.h>
int main()
{
char life_insurance[1];
char health[1];
int age=50;
health='B';
if (age<=55) && (health=='B')
cout<<life_insurance;
cin>>age;
return 0;
}

//编译通不过，我按照书上原文写的。

[珍惜生命远离CPP]

#include <iostream> 
using namespace std; 

int main() 
{ 
	char life_insurance[1]; 
	char health[1]; 
	int age=50; 
	health[0] = 'B'; 
	if( (age <=55) && (health[0]=='B') )
		cout <<life_insurance; 
	cin>> age; 
	return 0; 
}
