Question

c++的struct问题

#include<iostream>
#include<string>
using namespace std;
struct Person
{
string name;
int count;
};

int main( )
{
Person leader[3]={{"Li",0},{"Zhang",0},{"Fun",0}};
int i,j;
string leader_name;
for(i=0;i<10;i++)
{
cin>>leader_name;
for(j=0;j<3;j++)
if(leader_name==leader[j].name) leader[j].count++
}
cout<<endl;
for(i=0;i<3;i++)
{cout<<leader[i].name<<":"<<leader[i].count<<endl;}
return 0;
}
请问这个程序有什么问题？

Answer 1

看看这个行不？
#include<iostream>
#include<string>
using namespace std;
struct Person
{
string name;
int count;
};

int main( )
{
//Person leader[3]={{"Li",0},{"Zhang",0},{"Fun",0}};
Person leader[3];
leader[0].name="Li";leader[1].name="Zhang";leader[2].name="Fun";
leader[0].count=0;leader[1].count=0;leader[2].count=0;
int i,j;
string leader_name;
for(i=0;i<10;i++)
{
cin>>leader_name;
for(j=0;j<3;j++)
{
if(leader_name==leader[j].name)
leader[j].count++; //count后的分号没写
}
}
cout<<endl;
for(i=0;i<3;i++)
{cout<<leader[i].name<<":"<<leader[i].count<<endl;}
return 0;
}

Answer 2

if(leader_name==leader[j].name) leader[j].count++少个 ; 号

Answer 3

程序是对的,只是count++
后面掉了个";".测试通过。

#include<iostream>
#include<string>
using namespace std;
struct Person
{
string name;
int count;
};

int main( )
{
Person leader[3]={{"Li",0},{"Zhang",0},{"Fun",0}};
int i,j;
string leader_name;
for(i=0;i<10;i++)
{
cin>>leader_name;
for(j=0;j<3;j++)
if(leader_name==leader[j].name) leader[j].count++;
}
cout<<endl;
for(i=0;i<3;i++)
{cout<<leader[i].name<<":"<<leader[i].count<<endl;}

system("pause");
return 0;
}
