A. no return value B. int C. float D. char 相关知识点: 试题来源: 解析 根据上述对函数返回值类型定义方法的分析,结合题目描述:void func(void)中,函数名func前的void就是返回值定义,而void表示“无效或空白”,意味着这个函数不需要return语句,没有值传递到函数中。而选项B、C和D需要分别定义为int、...
Void return values Functions are not required to return a value back to the caller. To tell the compiler that a function does not return a value, a return type ofvoidis used. For example: #include<iostream>// void means the function does not return a value to the callervoidprintHi(){...
warn about it). Under C90 rules, this is legal, but the compiler will assume that the function returnsint. Your program's behavior is undefined, but yourvoidfunctionfunmight happen to behave as if it returned a value, and a call to it might happen to behave as if it used that value....

_.isUndefined = function(obj) { return obj === void 0; } 除了采用void能保证取到undefined值以外,还有其它方法吗?有的,还有一种方式是通过函数调用。如AngularJS的源码里就用这样的方式: (function(window,document,undefined){//...})(window,document); 通过...

If the } that terminates a function is reached, and the value of the function call is used by the caller, the behavior is undefined Thus omitting a return statement is undefined behaviour if the function returns a value (not void), and the caller uses the value. (As an exception...
