C语言实现方法一：
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
void split(char *src, const char *separator, char **dest, int *num)
{
char *pNext;
int count = 0;
if (src == NULL || strlen(src) == 0) return;
if (separator == NULL || strlen(separator) == 0) return;
pNext = strtok(src,separator);
while(pNext != NULL)
{
*dest++ = pNext;
++count;
pNext = strtok(NULL,separator);
}
*num = count;
}
int main()
{
char src[] = "Accsvr:tcp -h 127.0.0.1 -p\n 20018";
char *dest[128];
char *dest2[128];
int num = 0, num2 = 0;
int i, j;
split(src,":",dest,&num);
for (i=0;i<num;++i)
{
printf("|%s|\n",dest[i]);

for (j=0;j<num2;++j)
