i have my recipes.txt files filled
but when i run this program it arrive to debug1
and can't enter in the while that read the data and load them to the list

Answer is in fread documentation.

Code:

---

FILE *filePtr = fopen("recipes.txt","r");
recipe x;
struct element *xPtr;


  if(( filePtr = fopen("recipes.txt","rb"))== NULL){
      printf("Error in file opening");
  }

---

Opening the file twice? Once as text, once as binary? Huh?

just a way to understand what was wrong in fread, removed the first fopen :P
