getchar()
will read from stdin
, but your fscanf(inputFile, ...);
will read from inputFile
, you cannot use getchar()
to check whether you have reached the end of inputFile
.
You could use while (fscanf(inputFile, ...) == 7) {
to achieve your goal in this case.
From fscanf(3)
:
These functions return the number of input items successfully matched and assigned, which can be fewer than provided for, or even zero in the event of an early matching failure.
The value EOF is returned if the end of input is reached before either the first successful conversion or a matching failure occurs. EOF is also returned if a read error occurs, in which case the error indicator for the stream (see ferror(3)) is set, and errno is set indicate the error.
