is that c89 compatible?
does gcc header checking still work when you do that?
Wait, you can put #include headers in main() ?

I can forward declare functions inside a function in C

2022-08-28 06:33:51
It’s in the standard
yabadaba doo 2022-08-28 06:33:55
gcc complains tho
2022-08-28 06:34:03
Nested functions are a GNU extension

weird

yabadaba doo 2022-08-28 06:34:09
wait lemme try
capezotte 2022-08-28 06:34:18
yea, implicit function definition invalid in c99 or w/e
yabadaba doo 2022-08-28 06:34:21
oh the fuck
yabadaba doo 2022-08-28 06:34:24
didnt know

is that c89 compatible?

I included all headers

2022-08-28 06:34:56
yabadaba doo 2022-08-28 06:34:28
is that c89 compatible?

No, it uses c99 shit like size_t and uint64_t

yabadaba doo 2022-08-28 06:35:03
i meant the forward declaration
capezotte 2022-08-28 06:35:12

just noticed Factorial was declared in the function

Probably?

Hi dad I’m dumb

2022-08-28 06:35:37
capezotte 2022-08-28 06:35:12

Yeah that’s why including stdio.h in the function work too

capezotte 2022-08-28 06:36:29
typedefs work within functions
mind = blown
yabadaba doo 2022-08-28 06:37:16
well imma stop saying extern everytime like a retard now
2022-08-28 06:37:31
In dlang you can even import modules inside a loop
2022-08-28 06:37:35
based retards
yabadaba doo 2022-08-28 06:37:37
