About Compatibility
The C interpreter picoc employed in this tool is not a complete implementation of the C90 standard.
However, it is fully compatible with the C language at the syntax level, so there are no problems unless the programming is highly sophisticated.

The "#define" macro is implemented but can only be used in expressions. Substitutions cannot be made without regard to the structure of the program.
Function pointers" are not supported. Therefore, it is not possible to do object-oriented work with C structures.
Structures cannot be declared within functions. The same applies to unions. Declaration outside of a function is supported.
It supports "goto" but cannot jump before the current line.
The program does not support string literal concatenation such as ""ABC" "DEF"".
