WebIn the string.h header, we have one variable type named size_t. size_t is an unsigned integral data type and it represents the size of objects in bytes. It is also used as the return type for the sizeof operator. The size_t datatype is similar to the unsigned long long in the 64 -bit compiler and it is never negative. WebANSWER The correct syntax is #define _code_ far const which results in: far const unsigned char MyConst = {0xAC}; This compiles fine with the CX51 Compiler or with the C51 Compiler when you use the OMF2 Directive.
