没有见什么错误；去掉#include "stdafx.h"
然后char m[10];

[zhyinty]

#include <iostream>
#include <cstring>

struct month
{
 int number_of_day;
 char name[4];
};
using namespace std;
int main( )
{
 char *m;
 struct month months[2]={ {31,"jan"},{28,"feb"} };
 //months[2]={ {31,"jan"};{28,"feb"} };
 cout <<"input month's name:";
 cin>>m;
 for(int i=0;i <2;i++)
 if(strcmp(m,months[i].name)==0)
 {
 cout << m << ":" << months[i].number_of_day <<endl;
 break;
 };
}

没有返回值！

#include "stdafx.h" 
#include <iostream> 
#include <cstring> 
using namespace std;

struct month 
{ 
 int number_of_day; 
 char name[4]; 
};
 
int main() 
{ 
	char m[50] = {0}; 
	struct month months[2]={ {31,"jan"},{28,"feb"} }; 

	cout<<"input month's name:"<<endl; 
	cin>>m; 
	for(int i=0;i <2;i++) 
	if(strcmp(m,months[i].name)==0) 
	{ 
		cout<<m <<":" <<months[i].number_of_day <<endl; 
		break; 
	}
	else
	{
		cout<<"未找到"<<endl;
		break;
	}
 return 0;
}

编译环境注意下

[猫已经找不回了]

struct month 
{ 
	int number_of_day; 
	 char name[4]; 
}; 


int main( ) 
{ 
 char *m; 
 struct month months[2]={ {31,"jan"},{28,"feb"} };     
 //months[2]={ {31,"jan"};{28,"feb"} }; 
 cout <<"input month's name:"; 
 cin>>m; 
 for(int i=0;i <2;i++) 
 if(strcmp(m,months[i].name)==0) 
 { 
 cout <<m <<":" <<months[i].number_of_day <<endl; 
 break; 
 }              //去掉这个逗号
}
