Thread: How to read a txt file into an array

struct item

	break;

        fclose(fp);
        return 0;
}

ok I made changes to my code. and I have some warnings about types, functions etc.

I am mostly concernced about writing the code fore case 5, I am have no clue to go about it. And if there are still errors plz point them out

I am mostly concerned about your lack of indentation, which makes the code more awkward to read. You have already had this explained several times in this thread. If you want other people to look over your code for you, why don't you make an effort to make it properly readable?

I have only one problem now regarding case 4, I don't have any problem with the reset of my code

Code:

case 4: //allows user to choose items
                   printf("do you want to add choose item Y[1] N[0]");
		   scanf("%d",&input);
		   if(input==1)
		   {

		  
		  for (u=0;u<11;u++)
		  {
		  printf( "choose item for purchase\n" );
		  scanf("%d",&u);
		  printf("do you want to add choose item Y[1] N[0]");
		  scanf("%d",&input);

		  printf("%d %s %f\n", record[u].ID, record[u].name,record[u].price);
		  }
		  continue;
		  }
		  


		  else if(input==0){
		  break;
		  }

It keeps on asking me to add items and never stops, I want to know how to make it stop if I want it to . the item choosing works fine now, but I haven't found a way to stop the infinite process.
