有以下区别:1、主体不同:实参在调用有参函数时,函数名后面括号中的参数为“实际参数”。形参不是实际存在变量,又称虚拟变量。2、目的不同:实参可以是常量、变量或表达式,无论实参是何种类型的量,在进行函数调用时,都必须具有确定的值,以便把这些值传送给形参。需要注意当形参和实参不是指针类型...
Question 10.4 (c-faq.com) 中有回答,宏中有多个声明时,为了防止替换后引入多个 “;”。#define MACRO(arg1, arg2) {stmt1; stmt2;} // 在 if 条件语句分支调用 MACRO if(cond) MACRO(arg1, arg2); else /* some other code */ // 展开成 if(cond) {stmt1; stmt2;}; // 引入多个 “;”...

在asd函数中调用了er函数,而编译器之前并为看到有该函数的定义,因此编译器进行了一个隐含的函数原型解释,即inter(),到之后的er函数定义时,编译器发现同之前的隐含的原型不匹配,因此出错。includevoidasd(){ er();} voider(intb){ printf("er");} voidmain(){asd();} ...
