Thread: Scanf value trouble

Hey, as part of a function for a homework assignment I need to check whether scanf reached EOF.
the code line goes like this :

Code:

res=scanf(" %lf",&array[i][j]);
            if (res==EOF)
            {
                return i;
            }
             printf("cell is %d\n",array[i][j])

for some reason the array wont recieve any value from "scanf" , and when I check its values with printf it will stay all zeros

am I doing something wrong ?

From scanf() manpage:

RETURN VALUE
On success, these functions return the number of input items successfully matched and assigned; this 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 to indicate the error.
