    Question malloc of char arrays

    A friend tells me that in C when u malloc a char array u have to allocate length of the string + 2 (1 for the '\0' and 1 cause C needs it for some reason, i forget why tho). Just windering if this is right? and if i just statically allocate the array in the variables declaration that i only need to allocate for the size of the string.

    Thanx for any help you can give.

    For chars, you're simply specifying the number of bytes/chars to be allocated. That means the number of characters, plus one for the null character.

    Nope, it's just strlen(string) + 1 if you want to allocate memory for string
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    What Salem said.
    If you understand what you're doing, you're not learning anything.
