    229229the parameter's type becomes a type that I summarize as being the array-decayed type.
    230230The respective handlings of the following two parameter spellings shows that the array-spelled one is really, like the other, a pointer.
    231 %\lstinputlisting[language=C, firstline=40, lastline=44]{bkgd-carray-decay.c}
     231\lstinputlisting[language=C, firstline=40, lastline=44]{bkgd-carray-decay.c}
    232232As the @sizeof(x)@ meaning changed, compared with when run on a similarly-spelled local variariable declaration,
    233233GCC also gives this code the warning: ```sizeof' on array function parameter `x' will return size of `float *'.''
    234234
    235235The caller of such a function is left with the reality that a pointer parameter is a pointer, no matter how it's spelled:
    236 %\lstinputlisting[language=C, firstline=60, lastline=63]{bkgd-carray-decay.c}
     236\lstinputlisting[language=C, firstline=60, lastline=63]{bkgd-carray-decay.c}
    237237This fragment gives no warnings.
    238238
     
    240240Note the opposite meaning of this spelling now, compared with its use in local variable declarations.
    241241This point of confusion is illustrated in:
    242 %\lstinputlisting[language=C, firstline=80, lastline=87]{bkgd-carray-decay.c}
     242\lstinputlisting[language=C, firstline=80, lastline=87]{bkgd-carray-decay.c}
    243243The basic two meanings, with a syntactic difference helping to distinguish,
    244244are illustrated in the declarations of @ca@ vs.\ @cp@,
     
    259259Pointer decay does not affect pointer-to-array types, because these are already pointers, not arrays.
    260260As a result, a function with a pointer-to-array parameter sees the parameter exactly as the caller does:
    261 %\lstinputlisting[language=C, firstline=100, lastline=110]{bkgd-carray-decay.c}
     261\lstinputlisting[language=C, firstline=100, lastline=110]{bkgd-carray-decay.c}
