表示exit()永远不会返回,它是一个发散函数(divergent function)。 你可以用相同的语法编写自己的发散函数,这在某些情况下是很自然的: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 fnserve_forever(socket:ServerSocket,handler:ServerHandler)->!{socket.listen();loop{lets=socket.accept();handler.handle(...
在C语言中，当编译器提示“function should return a value”这一警告时，意味着在源文件中定义的某个函数没有按照其声明返回类型返回相应的值。解决这一警告的方法如下：确保main函数有返回值：在C语言中，main函数的标准声明是int main或int main，这意味着main函数应该返回一个整型值。通常，程序成功...
