Thread: Input multiple floats directly to array

You shouldn't have the newline character in that scanf format. It should just be:

Code:

scanf("%d", &len);

Oh, you're right. Except that the way we would usually handle it is by adding an extra space (just a space, not a newline) in front of the format of your other scanf.

Code:

    int len = 0;
    scanf("%d", &len);
    if (len == 0)
        return 0;
     
    char* str = malloc(len + 1);  // sizeof(char) is always (literally defined to be) 1, so it's not needed here
    scanf(" %[^\n]", str);   // extra space before format here causes whitespace (including newlines) to be skipped first.

Note that there is no 's' at the end of the format!!!
What exactly is this program supposed to do?

John - This is exactly the exercise of this topic.

Actually, I don't have any problem with the second scanf - only with the first one, when it looks like the first scanf you wrote - some tests are failed.
But, when I'm adding \n after %d - everything is just fine.

Zeus - The reason to these both conditions is that this length indicates only the maximum possible chars to iterate over - so the null-terminator can be occurred at any iteration...

EDIT:
John - got it.

Thank you guys!!
