为了简化对枚举类型的处理,我们可以定义一个通用的转换模板,该模板可以自动处理强枚举和弱枚举,将它们转换为字符串: template<typename T>std::string toString(T arg) {if constexpr(std::is_arithmetic_v<T>) {return std::to_string(arg);} else if constexpr(
As of z/OS V1R9, the execution of applications using the C/C++ IBM Open Class Library is not supported. Utilities The z/OS XL C/C++ compilers provide the following utilities: • The xlc utility to invoke the compiler using a customizable configuration file. • The c89 utility to ...

This option is effective only if used when compiling the main program. B.2.29 -fsimple[=n] Allows the optimizer to make simplifying assumptions concerning floating-point arithmetic. The compiler defaults to -fsimple=0. Specifying -fsimple, is equivalent to -fsimple=1. If n is present, it ...
The default LoRaWAN version, if no version is explicitly selected, is V1.0.3. LMIC_LORAWAN_SPEC_VERSION is defined as an integer reflecting the targeted spec version; it will be set to LMIC_LORAWAN_SPEC_VERSION_1_0_2 or LMIC_LORAWAN_SPEC_VERSION_1_0_3. Arithmetic comparisons can be ...
