文件读写

[ttssrs]

我的文件是这样的：
0,tcp,ftp_data,SF,854,0,0,0,0,0,0,1,0,0,0,0,0,0,0,0,0,0,2,2,0.00,0.00,0.00,0.00,1.00,0.00,0.00,151,119,0.42,0.47,0.41,0.02,0.00,0.00,0.45,0.01,normal.
0,tcp,ftp_data,SF,59,0,0,0,0,0,0,1,0,0,0,0,0,0,0,0,0,0,12,12,0.00,0.00,0.00,0.00,1.00,0.00,0.00,161,121,0.45,0.44,0.45,0.02,0.00,0.00,0.42,0.01,normal.
0,tcp,ftp_data,SF,854,0,0,0,0,0,0,1,0,0,0,0,0,0,0,0,0,0,4,4,0.00,0.00,0.00,0.00,1.00,0.00,0.00,171,122,0.49,0.42,0.48,0.02,0.00,0.00,0.40,0.01,normal.
请问如何获得每行最后的normal，并判断它是否在某个集合中？

strrchr() 函数查找字符在指定字符串中从后面开始的第一次出现的位置，如果成功，则返回指向该位置的指针，如果失败，则返回 false。

strrchr(buffer, ',');
找最后一个“,”。

显示不全？

[ttssrs]

什么显示不全？从0,tcp,ftp_data……到normal是一行。

能否再详细描述下你的需求，举个例子啥的

[witwolf]

char buffer[BUFSIZE];
每次读一行到buffer中（fgets)
char *p=buffer+strlen(buffer)-//（'\n','.'略过）
while(!p--!=',');
p++;
然后做一些处理就行了

上面是我的代码，把txt文件中的内容写入到excel里，我现在希望可以获得最后一个normal字符串，然后判断它是否在某个集合中。

[newfarmerchi]

int temp=0;
或是定义成static,或放在while循环的外面（之上）

[ttssrs]

try过了，不对……

好像没有明白我的意思，我现在遇到的问题是result是指向normal中的“n”的指针，但是我希望获得normal而不是n。

假设result现在指向n并将其保存到p1，如果后面还有字符，就再使用strtok寻找","，然后将其保存到p2，normal=strncpy(dst,p1,p2-p1+1);
大概就这个意思

[delphiwcdj]

偷懒点的办法用正则匹配

#include <iostream>
#include <string>
#include <regex>
#include <cassert>
using namespace std;

int main()
{
	string str = "每一行内容";
	tr1::regex rx("normal");

	// 使用 regex_search

	//assert( regex_search(str.begin(), str.end(), rx) );
	if (regex_search(str.begin(), str.end(), rx))
	{
		cout<<"find it!"<<endl;// ok，说明此行有normal
	} 
	else
	{
		cout<<"not find!"<<endl;
	}
}

[newfarmerchi]

normal.这是normal的格式，有一个. strcmp(result,"normal")
就不对了，可否strcmp(result,"normal."),如果有，再对normal.
进行处理。

[newfarmerchi]

#include <stdio.h>
#include <string.h>
int main ()
{
    char str[100]="00,0.00,0.45,0.01,normal.";
    char *p;
    p=strtok(str,",");
    
    while (p!=NULL)
    {
        if (!strcmp(p,"normal."))
        {
			printf("%s\n", p);
			strcpy(p,"normal");
			printf("%s\n",p);
		}
        p=strtok(NULL,",");
    }

    return 0;
}

谢谢指点，上面的问题解决了。下面这个定义报too many initializers错，这个怎么改呢？
char *attackType[]={{"normal"},
{"ip sweep","nmap","portsweep","satan","saint","mscan"},
{"back","land","neptune","pod","smurf","teardrop","apache2","mailbomb","udpstorm","processtable"},
{"perl","rootkit","loadmodule","buf_overflow","httptunned","ps","sqlttack","xterm"},
{"ftp-write","guess_passwd","multihop","phf","imap","spy","warezclient","waremaster","named","xsnoop","xlock","sendmail","worm","snmpgetattack","snmpguess"}};

[delphiwcdj]

改为：注意最多的一行元素，比如下面的10

	char *attackType[][10]={
		{"normal"},
		{"ip sweep","nmap","portsweep","satan","saint","mscan"},
		{"back","land","neptune","pod","smurf","teardrop","apache2","mailbomb","udpstorm","processtable"},// 10 
		{"perl","rootkit","loadmodule","buf_overflow","httptunned","ps","sqlttack","xterm"}};

我的问题还没有解决耶，怎么判断最后那个normal处于哪个集合呀？
