A clearer alternative is to put the semicolon by itself on the next line, either below the for or indented, where the intent is explicit, saying "Do nothing". For additional confirmation, a comment may be added: for ( i = 0; i < ARRAY_MAX; NewArray[i++] = 0 ) ; /* do nothi...
it informs the reader as to where each variables are relevant. Declaring variables when they're needed almost always leads to initialization (int x = 1;), rather than just declaration (int x;). Initializing
Avoid variable assignment with function call in declaration, except for single variables voida(void){/* Avoid function calls when declaring variable */int32_ta,b=sum(1,2);/* Use this */int32_ta,b;b=sum(1,2);/* This is ok */uint8_ta=3,b=4;} Exceptchar,floatordouble, ...
Every object and function declaration must be preceded by the keyword extern. (See below for why.) Now, for a very important rule: Avoid having nested includes, ever. I mean it. If you've ever tried to track a bug through the SunOS /usr/include maze, you'll understand why. Consider...

All header files should use #define to avoid multi-declaration. Naming format should be <PLATFORM>_<FILE>_H_ For example, the file adsp/dirver/include/adsp_driver_adc.h in platform adsp should have the following guard.: #ifndef ADSP_DRIVER_ADC_H_ #define ADSP_DRIVER_ADC_H_ ... #endif...
在源文件、头文件中的函数、方法或者类中可以使用using声明(using-declaration) // 在源文件中允许 // 但在头文件中必须在函数、方法或者类中 using ::foo::bar; 5. 名称空间别名可在源文件中、头文件的全局名称空间中,或者函数和方法中任意使用。 // 源文件中常用名称的受限访问 namespace fbz = ::foo:...
