    Comparing elements of character pointer arrays

    Code:
    I have arrays *arr and *aqq. I am trying to find the occurence of similar elements(strings) in the arrays...  
    
    this won't work..
       for(i=0;i<=count;i++)
       {
         found=0;
         for(j=0;j<=k;j++)
         {
           if(&arr[j]==&aqq[i])
           {
             found++;
           }
         }
     }
    
    and also this won't work...
    
       for(i=0;i<=count;i++)
       {
         found=0;
         for(j=0;j<=k;j++)
         {
           if(strcmp(arr[j],aqq[i])==0)
           {
             found++;
           }
         }
    }

    Post a larger snippet, like how you declare the arrays (and fill them), also stop posting your entire post in code tags!

    If you want to find strings in strings use strstr(), and what do you mean "this won't work"?

    here are the array declarations... don't know how to stop posting entire post in code tags..


    Code:
      char *arr[30000];
    
      temp=strtok(NULL,delimiters);
        arr[k]= (char*)temp;
      
       char *aqq[30000];
    
       while(fgets(c,sizeof(c),fq)!=NULL)
       {
         aqq[count]=c; count++;
       }
       int found;
       for(i=0;i<=count;i++)
       {
         found=0;
         for(j=0;j<=k;j++)
         {
           if(strstr(arr[j],aqq[i])==0)
           {
             found++;
           }
         }
