扑啦啦~

第四章的第三第四题还没写，那就先来第五吧，想想要去练车就心塞

NO 5

#include<iostream>
struct CandyBar
{
	char name[20];
	float weight;
	int calorie;
};
int main()
{
	using namespace std;
	CandyBar snack=
	{
		"Mocha Munch",
		2.3,
		350
	};
	cout<<"Snack is "<<'\n';
	cout<<snack.name<<'\n';
	cout<<snack.weight<<'\n';
	cout<<snack.calorie<<endl;
	return 0;
}

NO 7  嗯，这个是错的！

#include<iostream>
struct Pizza
{
	char name[20];
	float diameter;
	double weight;
};
int main()
{
	using namespace std;
	Pizza a[20];
	for(int i=0;i<20;i++)
	{
		cout<<"Enter pizza's name";
		cin>>a[i].name;
		cout<<"Enter pizza's diameter";
		cin>>a[i].diameter;
		cout<<"Enter pizza's weight";
		cin>>a[i].weight;
	}
	cout<<"please choose the number of pizza to realize it";
	int num;
	cin>>num;
	cout<<"The Number of "<<num<<" pizza is:"<<endl;
	cout<<a.[num].name<<'\n';
	cout<<a.[num].diameter<<'\n';
	cout<<a.[num].weight<<'\n';
	return 0;
}

so ,如何设计存储这些信息的结构？ 

第五章

NO 4  相信自己，我没错！！

<pre name="code" class="cpp">#include<iostream>
using namespace std;
int main()
{
	double price1=100;
	double price2=100;
	int i=0;
	while(price1>=price2)
	{
		price1=100*0.10+price1;
		price2=price2*0.05+price2;
		i++;
	}
	cout<<"After "<<i<<" years";
	cout<<" Cleo beyond Daphne."<<endl;
	cout<<"price1="<<price1<<";price2="<<price2<<endl;
	return 0;
}
