C-language string processing-----compressed string

Soon to graduate, recently a period of time has been looking at some of the basics of C language. Plan to share some of the latest gains from today. Let's write a program about string compression today.

Simply put, a string such as "Aaaaabcccddde", written as "A5b1c3d3e1". The code is as follows

void Yasu (char *s)
{

 char *p;
 Char reschar[100];//holds the compressed string
 memset (reschar,null,sizeof (Reschar));//string assignment is null
 p=s;
 int count=1;
 int k=0;

 int Len=strlen (s);

 for (int i=0;i<=len-1;i++)
 {
  if (P[i+1]==p[i])
  {
   count++
  }
  else
  {
   //sprintf (Reschar+strlen (Reschar), "%c%d", p[i],count);
   if ((count>=10) && (count<100))
   {
    int d1=count%10;
    int d2= (COUNT/10)%10;
    reschar[k++]=d2+ ' 0 ';
    reschar[k++]=d1+ ' 0 ';
   }
   else
   {
    
   reschar[k++]=count+ ' 0 ';

   }

  Itoa (count,reschar[k++],10);

   Count=1
  }


 }
 printf ("%s\n", Reschar);

}
