change the execution environment of your program.From the above, GDB and the General debugging tool is not the same, basically is to complete these functions, but in the details, you will find GDB this debugging tool is powerful, you may be more accustomed to the graphical debugging tools, but sometimes, the command line debugging tools have a graphical tool can not be done. Let's see.A debugging ExampleSOURCE program: TST.C1 #include 23 int func (int n)4 {5 int sum=0,i;6 for (i=0; i7 {8 sum+=i
Key points:After the program ends with an exception, the core code file program is generated to add the-g compilation option, which contains debugging information to locate the exception points in combination with the gdb and coredump files.
After the program ends abnormally, The coredump file is generated. The automatically generated coredump file varies with systems and settings.
Sample Code:
#include
int core_dump() {int i;for (i = 5; i >= 0; i--) {printf("(%d, %d)\n", i, 100 / i);}re
to know that Django's support for Unicode will allow your application to easily handle a wide variety of character sets, not just basic A-Z English characters.
Dictionaries and contexts
The dictionary data type of Python is a mapping of keywords and their values. The context is similar to a dictionary, and the context provides more functionality.
The variable name must start with an English character (A-Z or a-Z) and can contain numeric characters, underscores, and decimal points. (The decimal
With the continuous development of the Integrated Wiring System industry, more and more enterprises are producing integrated wiring systems. At the same time, the quality of each product is also different. This article describes the problems you should pay attention to when selecting, correct users' mistakes in selection, and select the products of enterprises with "Quality assurance" for consumers.

As the weather turned cold, Apple's mobile phones began to suffer many problems. Many netizens reported that during this period, Apple's mobile phones automatically shut down when there was about 20% of the remaining power. In this regard, Apple's after-sales staff also confirmed that this situation exists, and said that there is a problem with the product can be returned for repair, free of charge during the warranty period, outside the

Next, we analyze raw features and histogram features.

-hand accessories, because some products have not been used, their biggest problem is that the warranty time is shortened.
The biggest feature of these products is the large number of tags, which often mask the warranty tags of other businesses. If you find that all kinds of labels are printed on the product you purchased, and the labels are stacked together, the product is likely to be a backlog of goods
that it is not a wildcard because it is in square brackets.However, bash shell supports only integer operations. If you want to calculate the floating point, go down and look at it.
Floating Point Solution============
There are several solutions that can solve the integer limitation of mathematical operations in bash. The most common solution is to have a built-in bash calculator called BC.
### Basic BC usage
The bash calculator is actually a programming language that allows you to input fl

For example, if you publish a copy of this function library, whether it is free or charged, you must give all your rights to the recipient; you must ensure that they can also receive or get the original code; if you link this function library with other program codes, you must provide the complete object file and Program (Object File) to the recipient. After they modify this function library and re-compile it, you can link to the target file
the lifetime. One flash is called one P/E at a time, therefore, the lifetime of flash memory is also measured in P/E. The last generation of flash memory was officially announced as 5000 P/E, and the latest generation of flash memory is now 3000 P/E, therefore, many users intuitively think that the service life is not 2/5 less than the original one? Theoretically, this is good, but we all ignore this situation, that is, the technology adopted by the new SSD. Compared with the old one, it can re

We can use exclusion to narrow down the problem scope step by step and finally find the answer. First, let's assume it's a software problem. If we eliminate this possibilityCheck whether the hard disk data line is in contact with the power cord and is damaged.We will replace the hard disk on the computer. If this is not the case, it indicates that there is a problem with the original hard disk.It indicates that the problem is caused by other components except the hard disk, and then we use the e
