How can I detect if a line is empty?
1 2 3 4 5
I'm reading this with istream r
int n; r >> n
I want to know when I reach the space between 4 and 5.
I tried reading as char and using .peek() to detect \n but this detects the \n that goes after number 1 . The translation of the above input is: 1\n2\n3\n4\n\n5\n if I'm correct…
Since I'm going to manipulate the ints I rather read them as ints than using getline and then converting to int…
