    Why don't you just try it in a simple 3 line program?
    If you understand what you're doing, you're not learning anything.

    Hello,

    It will return 0. The double-quotation character is not within the alphabet. Rather, it will return non-zero if sent to isprint() since that character is printable.

    Segmentation Fault: I am an error in which a running program attempts to access memory not allocated to it and core dumps with a segmentation violation error. This is often caused by improper usage of pointers, attempts to access a non-existent or read-only physical memory address, re-use of memory if freed within the same scope, de-referencing a null pointer, or (in C) inadvertently using a non-pointer variable as a pointer.
