    Best way to scan in a string

    What is the best way to scan in a string that HAS white spaces if I want the scan to stop once it finds a '\n' character. I need to do this both from regular user input, stdin, and from a file. Should I use scanf, fscanf, or fgets? If so, what is the syntax to make the string stop getting data after it finds a newline character?

    Why don't you look up each function and read the documentation on them?
    scanf
    fgets

    Ive looked them up multiple times and everytime I try one, something ends up being wrong with the way I try to do it, so I come on here as ask what people think and they all give me different answers.. Some say use fgets, others say fgets is terrible or something...I'm just looking for a solid answer from someone who is experienced

    It's gets that's "terrible". fgets is good because it takes a buffer size parameter. The only thing to note about it is that it leaves the newline in the string.
