1. What kind of trouble does the outsourcing company sign in the morning? Don't sign in, don't deduct money, don't sign in and don't give money. To help you get rid of it, I wrote an automatic punching program.
2. I always wanted to write this program, but I had no idea
return this function, the ECMA said that this function object is not a value like a reference type, so its base object is null, Its value is implicitly converted to a global object, and then the value of this is determined with this base object. However, this value is undefined in ESC5 and is not converted. };}}; Alert (Object.getnamefunc () ()); //"The Window" (in non-strict mode)An example of a seniorvar name = "the window";var object = {Name: "My Object",Getname:function () {return this.name

function . In this case, the return type of main is int, and the return value of 0 is indeed a value of type int. extension: If the function does not need a return value, only void is used. If you need to end the function with a return, you do not need to follow the argument after return. Example: // There is a return type int getsum (int A, int b) { return a + b; } // no return type void Myprint () {std::cout this is test " Std::endl; return ;//This return statement may no
