How can I try to read a line from stdin (in fact, a file piped into stdin) and know if the read line is empty or not?
I want to read, for example:
How can I read these 4 lines? Using something like
for (int i=0; i<4; i++) scanf("%s", line);
the empty line will be skipped, and I don´t know that. Someone knows an easy way to do it?
PS.: I know how many lines I want to read.
