#include
int main() { printf("??( ??/ ??) ??< ??! ??> ??- ??= ??!\n"); }
You can run code by:
make run
And you will see this output:
# Compiled with old behavior: gcc -trigraphs ...
./trigraph-old
[ ] { | } ~ # |
# Compiled with new behavior: gcc ...
./trigraph-new
??( ??/ ??) ??< ??! ??> ??- ??= ??!
