#include<stdio.h>

    int j=0;
    int k=strlen(inString);
    for(i=0;i<k;i++)
    {
        if(inString[i]==inString[i+1])
            count++;
        else 
           {
              if(1!=count)
              {  
                 outString[j]=count+'0';
                 j++;
                 outString[j]=inString[i]; 
                 j++;
              }
              else 
              {

              count=1;
           }
    }
    outString[k]='\0';
    return 0;
 
}
int main()
{

改成用指针表示，函数实现方法相同：
#include<stdio.h>
#include<string.h>
int zigString(const char *stringInput,char *stringOut)
{
    #ifdef DEBUG
    if(NULL==stringInput)
    return 0;
    #endif
    const char *inString1=stringInput;
    const char *inString2=stringInput+1;
    char *outString=stringOut;
    int count=1;
    while(*inString1)
    {
        if(*inString1==*inString2)
            count++;
        else 
           {
              printf("hello\n");
              if(1!=count)
              {  
                 
                 *outString=count+'0';
                 outString++;
                 *outString=*inString1; 
                 outString++;
              }
              else 
              { 
                 *outString=*inString1;
                 outString++;
              }
              count=1;
           }
          inString1++;
          inString2++;

    }
    *outString='\0';
    return 0;
 
}
int main()
{
 char input[100]={"abbbbccccddddaaaaa"};
 char output[100]={0};
 zigString(input,output);
 printf("%s\n",input);
 printf("%s\n",output);
 return 0;
}
