Answer 1

Can you show use the content of the file ?

What do you see when you put "abc" in the file.

GetC stands for
"Get character"
Why should it read line by line?

Answer 2

sneeze the file's contents are
Inventory
100 Widget 0.29
End of List

I expect it to read character by character only. But for some reason I get unknown charcters printed infinitely. Could it be the type of c? Should it be int instead of char?

Answer 3

sneeze okay thank you I got it. The type of c should be int instead of char as fgetc returns the ASCII values of the characters
