What new capabilities do user-defined literals add to C++?
...'re out of luck until your lobbying to add your quantum wave functions (or 3D points, or whatever basic type you're using in your field of work) to the C standard as a built-in type succeeds.
In C++11, you just can do it yourself:
Point p = 25_x + 13_y + 3_z ; // 3D point
Is it bloated? No, the nee...

How do I disable form resizing for users? [duplicate]

Change the FormBorderStyle to one of the fixed values: FixedSingle, Fixed3D,
FixedDialog or FixedToolWindow.
The FormBorderStyle property is under the Appearance category.
Or check this:
// Define the border style of the form to a dialog box.
form1.FormBorderStyle = FormBorderStyle.FixedDialog;...

从业务角度来讲，这是不经济的，因为这是对客户的免费内容，本应该最快搞完交差。
也就是说，这样的训练会降低短期绩效（速度太慢）。
但是从能力提升的角度来说，这会让一个团队成员利用一个非紧急工作，最大...
