请教一个初级的C++问题，尽情的笑话我吧！

#include <iostream>
using namespace std;
class M
{
public:
M() {cout<<"i love cpp"<<endl;}
}
int main(void)
{
M a();
cin.get();
}
运行结果为：'M' followed by 'int' is illegal (did you forget a ';'?)
return type of 'main' should be 'int' instead of 'M'

5 个解决方案

#1

M a(); 这是一个函数声明，吧()去掉

#2

class M
{
public:
M() {cout<<"i love cpp"<<endl;}
} //这儿加";"分号

int main(void)
{
M a(); //改为 M a;
cin.get();
}

#3

class M
{
public:
M() {cout<<"i love cpp"<<endl;}
}；

#4

class M
{
  public:
  M() {cout<<"i love cpp"<<endl;}
};    //这儿加";"分号

int main(void)
{
  M a;   //改为 M a;
  cin.get();
  return 0;  //这里加上返回语句
}

#5

//改为 M a;
