mark.c: 2 * bad array index ?

[dcb314]

[mark.c:31] -> [mark.c:29]: (warning) Array 'marks[10]' accessed at index 10, which is out of bounds. Otherwise condition 'mark_number<=10' is redundant.

if(mark_number <= MAX_MARK)
{
    marks[mark_number] = pos;
}

Maybe better code

if(mark_number < MAX_MARK)
{
    marks[mark_number] = pos;
}

[mark.c:51] -> [mark.c:49]: (warning) Array 'marks[10]' accessed at index 10, which is out of bounds. Otherwise condition 'mark_number<=10' is redundant.
