C++ Contest Code preprocessor

大概可以拿来方便拉模板

变量名、语法都是瞎整的你感觉有用随便用好了..

#include<bits/stdc++.h>

map<string,int>fp;
inline bool is_space(char c){return c==' '||c=='\t';}

		if(t[i]!=strpat[i])
			return 0;
	return 1;
}

	char*Line_Buffer=new char[1<<20];
	while(!feof(inFile)&&fgets(Line_Buffer,1<<20,inFile)){
		// process line
		printf("%s%s",intd,Line_Buffer);
	}puts("");
