谢谢你们了，楼主找到一个好的解决方法了。。

#include<iostream>
#include<string>
using namespace std;
const int Max=30;
struct car
{
char make[Max];
int year_made;
};

void main()
{
int num_car;int i=0;
cout<<" How many cars do you wish to catolog?____\b\b";
cin>>num_car;
while(cin.get() != '\n') //①
;
car *c=new car [num_car];
for(i=0;i<num_car;i++)
{
cout<<"Car #"<<(i+1)<<":"<<endl;
cout<<"Please enter the make:";
cin.getline(c[i].make,20); //// 整行输入存在错误。。
cout<<"Please enter the year made:";
cin>>c[i].year_made;//cin.get(c[i].year_made,Max);
while(cin.get()!='\n')
; //②
}
////////
cout<<"\n\aHere is your collection:"<<endl;
for(i=0;i<num_car;i++)
{
cout<<c[i].year_made<<" "<<c[i].make<<endl;

C/C++ code
#include<iostream>
#include<string>

void main()
{
std::string buffer_str;
std::getline(std::cin, buffer_str);
std::cout << buffer_str << std::endl;
}

实践证明这段代码，输入空格是没有问题的……

谢谢，之前我试过这种，getline(cin,str)可以运行成功;但是换成getline(cin,c[i].make)就不行，让人很DT;

#include<iostream>

#include<string>





void main()

{

    std::string buffer_str;

    std::getline(std::cin, buffer_str);

    std::cout << buffer_str << std::endl;

}

实践证明这段代码，输入空格是没有问题的，LZ可以亲试

string 试过了，不行。主要是那一行怎样解决整行输入的问题。。

如果make是分开的名字就行不通了，比如Had Sun这种..
