如何快速分隔一个字符串，并将分隔后的数个串放到一个指针数组中

[horicon]

比如源串为"aa,bb,cc,dd,..."

如何将它存成
argv[0]="aa"
argv[1]="bb"
argv[2]="cc"
argv[3]="dd"

源串长度不定，分隔后，数组元素多少也不定，用C语言怎么解决，求助各位大神

[horicon]

怎么没人啊

[机智的呆呆]

strtok
new char*[n]

[fthislife]

看看下面这个：

#include<stdio.h>
#include<malloc.h>
#define OUT
int func(char OUT ***pp,char *p,char c,int *maxlen)
{
	int num=0,i,j=0,temp=0,temp1=temp;
	char *s=p,char **ppp=NULL;
	for(;*s!='\0';s++)
	{
		while(*s!=c&&*s!='\0')
		{
			temp1++;
			s++;
		}
		if(temp<=temp1)
			temp=temp1;
		temp1=0;
		if(*s==c)
			num++;
	}
	ppp=(char**)malloc(sizeof(char*)*num);
	for(i=0;i<=num;i++)
		ppp[i]=(char*)malloc(sizeof(char)*(temp+1));
	s=p;
	for(i=0;i<=num;i++)
	{
		for(j=0;j<temp&&*s!='\0'&&*s!=c;s++,j++)
		{
			ppp[i][j]=*s;
		}
		ppp[i][j]='\0';
		s++;
	}
	*pp=ppp;
	*maxlen=temp;
	return num+1;
}	
void main()
{
	char a[]="aa,bb,ccc111,dd,dddd111",**p;
	int i,t,num=func(&p,a,',',&t);
	for(i=0;i<num;i++)
	{
		printf("%s\n",p[i]);
	}
}

把字符串写进文本中 fseek读 指针移动 和strcmp(‘，’,)进行比较 匹配成功就读取换另一个数组存储

使用strtok针对,做分割。
使用malloc分配内存区域。
如果做成链表会很方便
typedef struct tagList
{
char *pchStr; // 用于malloc
struct tagList *ptNext; // 指向下一个
}TList;

用strtok分割

[暮雨晨舟]

strtok 没使用过~

我更喜欢用指针数组

基于链表的简单实现

strtok似乎不满足楼主的要求

char s[]="aa,bb,cc,dd,...";

int main() 代码测试可以这样
实际使用 可以方便
改成成 int main(int argc ,char *argv[])
