Why use the move semanticsIt exists to reduce the cost of copying objects, see the following sections of the code later in this articleLeft and right valuesThere are two ways to judge left and right values1. The value to the left of the equals sign is called the Lvalue and the right side of the equals sign is called the Rvalue2. In addition, in C + + There is als

The old saying long talk, the CSS of the non-fixed layout, whether it is the interview or in peacetime work, such layout has been used, very common, so today I took out in a nagging, not only to own a memo storage, but also a learning to consolidate the reference, know everyone will, or to remember, not for other, To lay a good foundation.
Say too much, directly on the code, a look can understand. Maybe you'll be dismissive of the simple, but I like to write some ... As a rookie, we must study

Everyone good, recently a period of time has been immersed in the station, for the site poured a lot of painstaking effort, but did not see a great effect, one is because of their own energy is limited, and perhaps their own technology is still lacking. Recently, my friend has a small station, do not know how the site is down the right, he asked me to help see, although he knows this piece is not too much, but the time is still a study of this piece.
1. Arithmetic left shift logic left
The arithmetic left shift and the logical left shift are the right 0:
Like 00101011.
Shift arithmetic left one: 01010110
Shift logic left one: 01010110
For binary values, the left-shift n-bit equals the original value multiplied by 2 of the n-th square.
For example, 110,100 binary is 26, left two digits after 011010 00 turn to decimal is 104 times 26.
