a function always gets a copy of the thing being passed, as if there were an assignment statement assigning the value to the parameter. For instance, passing an int value to a function makes a copy of the int, and passing a pointer value makes a copy of the pointer, but not the data...
main 函数是每一个可执行程序所必须包含的,一般来说都是在启动后第一个执行的函数(如果有 init() 函数则会先执行该函数)。 4. 下一行 /*...*/ 是注释,在程序执行时将被忽略。单行注释是最常见的注释形式,你可以在任何地方使用以 // 开头的单行注释。多行注释也叫块注释,均已以 /* 开头,并以 */ 结...
