字符串输入输出问题
此程序纯在这样的BUG,就是输入名字的时候,如果输入带空格的名字,就会出错
如DK YANG.
如何修改出问题的部分呢?
程序如下:
#include <iostream>
const int SIZE=20;
struct donation
{
char name[SIZE];
double money;

};

int main()
{
using namespace std;
int number;
cout < < "Enter the number of donators: ";
cin> > number;
donation *Dn=new donation[number];
cout < < "Enter all of the information of donators: "
< < "include names and money\n ";
for(int i=0;i <number;i++)
{
cout < < "Name:\n ";
cin> > Dn[i].name;//问题在这里如何修改?
cout < < "Money:\n ";
cin> > Dn[i].money;
}
for(i=0;i <number;i++)
{
if(Dn[i].money> 10000)
{
cout < < "Grand Patron: " < <Dn[i].name < < '\t ';
cout < < "Money: " < <Dn[i].money < < "\t ";
cout < <endl;
}
else if(Dn[i].money> 0&&Dn[i].money <=10000)
{
cout < < "Patron: " < <Dn[i].name < < "\t ";
cout < < "Money: " < <Dn[i].money < < "\t ";
cout < <endl;
}
else
cout < < "None!\n ";
}
delete [] Dn;
return 0;
}

[解决办法]
解决了!
主要原因是回车符的处理!代码见下.
#include <iostream>
const int SIZE=20;
struct donation
{
char name[SIZE];
double money;

};

int main()
{
using namespace std;
int number;
cout < < "Enter the number of donators: ";
cin> > number;
donation *Dn=new donation[number];
cout < < "Enter all of the information of donators: "
< < "include names and money\n ";
char a;
cin.getline(&a, 1);
for(int i=0;i <number;i++)
{
cout < < "Name:\n ";
//cin> > Dn[i].name;//ÎÊÌâÔÚÕâÀïÈçºÎÐÞ¸Ä?
cin.getline(Dn[i].name, 20);
cout < < "Money:\n ";
cin> > Dn[i].money;
cin.getline(&a, 1);
}
for(i=0;i <number;i++)
{
if(Dn[i].money> 10000)
{
cout < < "Grand Patron: " < <Dn[i].name < < '\t ';
cout < < "Money: " < <Dn[i].money < < "\t ";
cout < <endl;
}
else if(Dn[i].money> 0&&Dn[i].money <=10000)
{
cout < < "Patron: " < <Dn[i].name < < "\t ";
cout < < "Money: " < <Dn[i].money < < "\t ";
cout < <endl;
}
else
cout < < "None!\n ";
}
delete [] Dn;
return 0;
}
