Здравейте,
Опитвам се да си сглобя някакво обобщено обработване на менюта на Си,
Долният код го компилирам като C++ и като C .
В първия случай ми дава грешка
"main.cpp|56|error: cannot convert 'const singlefieldstruct* (*)[3]' to 'singlefieldstruct**' in initialization"
Във втория случай му издава предупреждение
||=== Build: Release in pm1 (compiler: GNU GCC Compiler) ===|
main.c|48|warning: initialization from incompatible pointer type
warning: (near initialization for 'line1descriptor.fieldsinlineptrs') [enabled by default]|
Изпълнението ми изглежда коректно.
Това се случва на редовете отбелязани съсъ звездички.
Какво предизвиква тия грешки/предупреждения, какво правя грешно?
