Thread: reading data format into program

I'm working on that education quizzer program that I got some hints on awhile ago. Now I'm adding the ability to read and write the program data on disk.

The problem that I am having is reading the data. When the data is displayed newlines are shown where there shouldn't be any. I think newlines are being added during the loading process.

Here's my code to load the data into the program

Code:

int loadDatabank(char filename[25])
{ //loads databank off disk
   int ctr;
   int i;
   FILE *fPtr;
   char buffer[80];
   printf("Enter filename to be loaded: ");
   scanf("%s", filename);
   strcat(filename,".txt");
   fPtr = fopen(filename, "r+");
   if(!fPtr)
   { printf("A problem occurred whie trying to open the file.\n");
      pressKey();
      return 0;
  }
  fseek(fPtr,0L,SEEK_SET);
  fgets(buffer,sizeof(buffer),fPtr);
  sscanf(buffer,"%d",&numList);
  for(ctr = 0;ctr <= numList; ctr++)
 {
    fgets(buffer,sizeof(buffer),fPtr);
    sscanf(buffer,"%d",&list[ctr].type);
    fgets(list[ctr].question,sizeof(list[ctr].question),fPtr);

    if(list[ctr].type == QUEST_MULTIPLE)
   {
       fgets(buffer,sizeof(buffer),fPtr);
       sscanf(buffer,"%d",&list[ctr].nChoices);
       i = 0;
       while(i < list[ctr].nChoices)
       {
           if(fgets(list[ctr].choices[i],sizeof(list[ctr].choices[i]),fPtr) == NULL)
           break;
           i++;
           }
        }
        fgets(list[ctr].answer,sizeof(list[ctr].answer),fPtr);
             strtok(list[ctr].answer,"\n");
        }

       fclose(fPtr);
       printf("File successfully loaded.");
       pressKey();
   return 1;
}

File format:

Code:

4  /* total entries in file */
0 /* question type: 0 direct, 1 multiple choice, ect. */
What is 1 + 1? /* question*/
2 /*answer*/

The perimeter of a square is 24. What is the area?

36 sq. in.
6 sq. in.
60 sq. in.

Well this fgets() leaves the newline
fgets(list[ctr].question,sizeof(list[ctr].question),fPtr);

Adopt a consistent approach, like
- always fgets() into the same buffer, then strcpy() the result to where you want it / sscanf() it to extract info
- always remove the \n before doing anything else
