有没有main函数？

对照这个需要理解字符指针比较字符串，今天看了答案，隔天写

貌似让我直接写成了string类的比较了。。。原文地址

#include<iostream>#include<vector>#include<sstream>#include<fstream>#include<cstdlib>#include<list>using namespace std;bool Equal(string &a,string&b){if(a==b)return true;else return false;}int main(){ifstream fin;fin.open("source.cpp");if(!fin){cerr<<"Open error..."<<endl;exit(1);}string findword="main()";string  word;int num=0;    while(fin>>word)if(Equal(word,findword))num++;    cout<<findword<<"出现"<<num<<"次。。。"<<endl;    fin.close();return 0;}
