EN编写一个名为carpet.py的程序，该程序使用一个名为carpet_cost的空函数来计算和显示矩形房间地毯的成本。功能应该以房间的长度(以英尺为单位)、以英尺为单位的房间宽度以及每平方码地毯的费用作为论证。这三个值应该从主函数中的用户输入中获得。carpet_cost函数应以货币格式计算和显示地毯的成本，并在第一个数字上
Example(示例) 代码语言:javascript 代码运行次数:0 运行 AI代码解释 voidf(void);// badvoidg();// better Note(注意) Even Dennis Ritchie deemed void f(void) an abomination. You can make an argument for that abomination in C when function prototypes were rare so that banning: 哪怕丹尼斯·里奇...
For example, afunctionthat prints a message doesn't return a value. The code in C++ takes the form: void printmessage ( ) { cout << "I'm a function that prints a message!"; } int main ( ) { printmessage ( ); } A void function uses a heading that names the function followed ...

function example(param = void 0) //确保参数未传入时明确为undefined 超链接行为控制是void的经典应用场景。当需要在HTML锚点标签中阻止默认跳转行为时,开发者常使用javascript:void(0)作为href属性值。这种写法既执行了必要的JavaScript逻辑,又避免了页面跳转或刷新: 点击执行操作 立即执行函数表达式(IIFE)与void...
In this example, let's create a void function that generates a plot without returning anything −function plotSineWave() % Generate a sine wave and plot it x = linspace(0, 2*pi, 100); y = sin(x); % Plot the sine wave plot(x, y); title('Sine Wave'); xlabel('x'); ylabel...
