Full code with compilation instruction and expeced output description

Trying to get the streams to work and skip the first line but using the stdin insists on reading the first line, is it normal? seems to me that the cursor isn't getting updated after readf reads the first input?


/*
    Compiling it the following way:

    dmd streamfail.d
    ./streamfail < input.txt

    Contents of `input.txt`
    9
    11 2
    3 4
    5 6
    7 8
    9 10

    Expected Output:
    [11, 2]
    [3, 4]
    [5, 6]
    [7, 8]
    [9, 10]

    Current Output:
    []
    [11, 2]
    [3, 4]
    [5, 6]
    [7, 8]
    [9, 10]
