C语言预处理是C语言编译过程的一个阶段,它在编译之前对源代码进行一系列的处理操作,包括宏替换、文件包含、条件编译等,最终生成经过预处理的代码,然后再进行编译。 C语言预处理的主要功能有: 宏替换:通过使用#define定义宏,可以将一段代码或表达式抽象成一个标识符,在编译时将标识符替换成对应的代码或表达式。 文件...
Types of Functions in C Programming The C programming language includes a variety of functions, which are enumerated below. Main function – This function marks the start of any C program. It is a preset function that is first executed when a program is run. The main function may call other...

程序是一连串的 函数定义(function-definitions)或声明(declarations) 文法: translation-unit: external-declaration translation-unit external-declaration external-declaration: function-definition declaration As discussed in 5.1.1.1, the unit of program text after preprocessing is a translation unit, which ...
to provide a corresponding number of parameters, and the parameter types should be the same as those in the function definition. After calling the function, the program will jump to the function body of the called function to perform the corresponding task, and return to the calling function ...

function c(){ var a=10; function bb(){ return a*2; } return bb();} alert(c())函数对自身内部函数的调用 function d(a,b){ function dd(a){ return a+2 } return c=dd(a)+dd(b); }alert(d(2,3))函数对其他函数的调用 function add(a,b...
a coder might call function improperly without the compiler detecting errors that may lead to fatal execution-time errors that are difficult to detect. Syntax of function prototype in C programming: return_type function_name( type argument1, type argument2, ...);...
generate a program flowgraph General options: -d, --depth=NUMBER Set the depth at which the flowgraph is cut off -f, --format=NAME Use given output format NAME. Valid names are `gnu' (default) and `posix' -i, --include=CLASSES Include specified classes of symbols (see below). Prepe...
