2017华为软件精英挑战赛读文件和写文件源代码（C++）

在delop.cpp中

struct Init Var;

void deploy_server(char * topo[MAX_EDGE_NUM], int line_num,char * filename)
{
	initial(topo,line_num);
	

	char *topo_file=new char[60000];
	char *str=new char[20];

	sprintf(str,"%d\n\n",Var.connode_num);
	strncat(topo_file,str,4);

	for(int i = 0;i < Var.connode_num;i++)
	{
		sprintf(str,"%d %d %d\n",Var.con_linkID[i],i,Var.con_needband[i]);
		strncat(topo_file,str,10);
	}
	
	printf("\n\n %s", topo_file);

	write_result(topo_file, filename);
