    Amusing corner case...

    What number comes after 0xE? Let's find out!

    #include <stdio.h>
    int main(int argc,char *argv[]) {

    $ gcc -o a a.c -Wall -pedantic
    a.c: In function ‘main’:
    a.c:4:17: error: invalid suffix "+1" on integer constant

    That's because 'E' is used in floating point literals. The compiler thinks 0xE+1 is nnnE+1 as in 3.14e+1 literal. Try to use (0xE)+1 instead.
