fgets() not waiting for input

Question

I wrote the following code:

int N;
scanf(\"%d\", &N);
int i;
for (i = 0; i < N; i++) {
  char line[LINE_MAX];
  if (fgets(line, LINE_MAX, stdin) != NU         


        

Answer 1

You can place a call to fflush() just after the scanf() like this:

int N;
scanf("%d", &N);
fflush (stdin);
int i;
... (rest of code)...

So the newline character ges erased from the stdin buffer and the next fgets() will stop to ask for input.
