It is unrealistic to use sscanf or strtok to parse the following three statements and succeed:
Char str1 [] = "$ uplmc, 121252.000, A, 3958.3032, N, 11629.6046, E, 15.15, 359.95, 070306, A * 54 ";Char str2 [] = "$ uplmc, 013244.013, V, 2949.0092, N, 12133.1459, E, 290908, N * 78 ";

What are the limitations of the Aliyun server
There are only instances of current management console support for tagged resources.
Each label is made up of a pair of key value pairs.
You can bind up to 10 labels per instance.
The label key for each label on an instance must be unique, and the label of the same tab key will be overwritten.
The label information in each region is not interoperable, for example, the label created in East China 1 (H
programming, which is limited by the computer hardware resources or software resources. For example, the server's bandwidth is only 2mb/s, the download speed of a resource is 1mb/s per second, the system starts 10 threads to download resources, download speed does not become 10mb/s, so in concurrent programming, consider the limitations of these resources. Hardware resources limit the bandwidth of the upload/download speed, hard disk read and write s
For code like, duplicate, only parameter, return value type is different, of course, is the generic method, generic class.
The use of generic methods, generic classes, can be a good way to improve code reuse.
However, it is not always a good time to adopt a generic type.
As mentioned above, arguments and return values are different, and you can use generics. However, these generics are used only on parameters, return values, and may not be appropriate if they are used within the body of the f
Even someone asked me "There are 5 text boxes on the page, each text box can only enter one character, how to use JS to implement the user input the first text box after the focus of automatic jump to the second." ”。
I said this function is not the tab to do it? Once the user has entered, you can click the TAB key, and the user can also control whether to switch to the next (because the user also has the possibility of input errors).
But he insisted on insisting that the boss asked for it. I

Label:Recently in the study of MongoDB, my machine is 32-bit Windows 7 Home Basic, search related data is seen
32-bit machines are limited by address space, so the maximum data space for a single instance is only 2gb,64 (128T), so it is recommended to use a 64-bit machine deployment
This is also described in the official documentation.
MongoDB is a server process, which runs on Linux, Windows and OS x. It can be run both as a or 64-bit application. We recommend running
