fscanf(....) question.

[powerb23]

Hi,
I would like to write an fscanf statement to read the first integer value at the start of the line.This is what i was using:

int c = 0;

int sr = fscanf(inFile, "%d", &c);

I was puzzled as to why this returned a value of 1 when the line contained:

8as 12


Your help will be appreciated.

doesnt fscanf return the number of fields successfully read ? in your case, 8 would have been successfully read into c and you get 1 in sr.

Which begs the question "what answer were you expecting"?

Given
int sr = fscanf(inFile, "%d", &c);
And a file containing
8as 12

sr would be 1 (ie, an integer was found, converted and assigned)
c would be 8 (the result of the conversion)
'a' would be the next character to be read from the input file.
