dear experts,
please try running the following record keeping program. the text file is manipulated wrongly at the end of every execution cant seem to find the error. pls help if possible

Code:
#include<stdio.h>
#include<string.h>

struct player
{
 char name[20];
 int score;
};

int read(struct player p[1000]);
void write(struct player p[1000],int idx);

int main()
{
 struct player p[1000];
 int size;
 int idx;
 char pname[20];
 int same = 1;
 int ctr;
     
 idx = read(p);        
 size = idx + 1;
 
 while(same == 1)
  {
   printf("Enter your first name(only) MAROONED player!\n");
   scanf("%s",pname);
   
   ctr = 0;
   while(ctr < size) 
    {
     if(strcmp(((p[ctr]).name),pname) == 0);
      { 
       same = 0;
       break;
      }
     ctr++;
    }
   if(ctr == idx)
    {
     strcpy(((p[size]).name),pname);
     ((p[idx]).score) = 0;
     break;
    }
  }

printf("\n%s %s\n",p[1].name,p[2].name);
 write(p,size);
 
system("pause > null");
return 0;          
}



int read(struct player p[1000])
{
int i=0;
FILE *fr;
 
  fr = fopen("player.txt","r");        
  
  if(fr == NULL)
   {
    printf("ERROR : unable to read!\n");
    return 0;
   } 
  while(fscanf(fr,"%s%d\n",((p[i]).name),&((p[i]).score)) == 2);        
   {
    i++;
   }       
 
 fclose(fr);
 
return i;
}

void write(struct player p[1000],int idx)
{
 FILE *fw;
 int ctr;
 
 fw = fopen("player.txt","w");
 
 if(fw == NULL)
  {
   printf("ERROR opening file!\n");
   return;
  }
 
 for(ctr=0;ctr<(idx+1);ctr++)
  {
   fprintf(fw,"%s %d\n",((p[ctr]).name),((p[ctr]).score));
  }

fclose(fw);

printf("\nplayer records updated\n");

return;
}


the player.txt text file initially has

Code:
john 1
peeter 2
mary 8
text file after execution

Code:
mary 8
