function-declaration

问题 Why does the first one of these examples not work, but all the other ones do? // 1 - does not work (function() { setTimeout(someFunction1, 10); var someFunction1 = function() { alert(\'here1\'); }; })(); // 2 (function() { setTimeout(someFunction2, 10); function someFunction2() { alert(\'here2\'); } })(); // 3 (function() { setTimeout(function() { someFunction3(); }, 10); var someFunction3 = function() { alert(\'here3\'); }; })(); // 4 (function() { setTimeout(function() { someFunction4(); },

问题 When I was studying for my undergraduate degree in EE, MATLAB required each function to be defined in its own file, even if it was a one-liner. I\'m studying for a graduate degree now, and I have to write a project in MATLAB. Is this still a requirement for newer versions of MATLAB? If it is possible to put more than one function in a file, are there any restrictions to this? For instance, can all the functions in the file be accessed from outside the file, or only the function that has the

问题 What is useful about this C syntax — using \'K&R\' style function declarations? int func (p, p2) void* p; int p2; { return 0; } I was able to write this in Visual Studios 2010beta // yes, the arguments are flipped void f() { void* v = 0; func(5, v); } I don\'t understand. What\'s the point of this syntax? I can write: int func (p, p2) int p2; { return 0; } // and write int func (p, p2) { return 0; } The only thing it seems to specify is how many parameters it uses and the return type. I guess
