题目如下：

代码如下：

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
int spitStr(const char *inbuf, char c, char **outbuf, int *count)
{
  outbuf = (char **)malloc(sizeof(char*) * 10);   //分配内存
  for (int i = 0; i < 10; ++i)
  {
    outbuf[i] = (char *)malloc(sizeof(char) * 50);
  }
  if (outbuf == NULL)
  {
    return -1;
  }
  //分离字符
  for (int i = 0,j=0,k=0; inbuf[i] != '\0'; i++,k++)
  {
    if (inbuf[i] != c)
    {
      outbuf[j][k] = inbuf[i];
    }
    else
    {
      outbuf[j][k] = '\0';
      j++;
      k = -1;
      (*count)++;
    }
  }
  for (int i = 0; i < *count; i++)
  {
    printf("%s \n", outbuf[i]);
  }
  return 0;
}
void freeMem(char **p)
{
  for (int i = 0; i < 10; ++i)
  {
    if (p[i] != NULL)
    {
      free(p[i]);
      p[i] = NULL;
    }
  }
  if (p != NULL)
  {
    free(p);
    p = NULL;
  }
}
int main()
{
  int ret = 0;
  int count = 0;
  char *s1 = "asdasd,wgeasd,wagawd,asgfas,asfgwd,asudwsd,";
  char **p1 = NULL;
  ret = spitStr(s1, ',', p1, &count);
  free(p1);
  printf("line:%d\n", count);
  if (ret != 0)
  {
    printf("splitError!!!\n");
  }
  
  system("pause");
  
  return 0;
}
