C++ Standard Templates (STL) – Type support (numeric limits, is_specialized, is_signed, is_integer)
Numerical limits Defined in header file Defined in the header file template< class T > class numeric_limits; The numeric_limits class template provides a standardized way of querying properties of various arithmetic types (e.g. the maximum possible value of type int is std::numeric_limits::max() ). Identify whether std::numeric_limits is specialized for this type std::numeric_limits<T>::is_specialized static const bool […]
Program in Ubuntu system and STM32 (Keil) to display the assigned addresses and compare them.
1. Some variables and memory allocation in C program 1. Global variables Variables defined outside all functions are called global variables. By default, their scope is the entire program, that is, all source files, including .c and .h files. For example: int a, b; //Global variables void func1(){<!– –> //TODO: } float x,y; //global variables […]

python interface automation 24-interface projects with tokens are designed using the unittest framework
Get token When automating interfaces, we often encounter multiple test cases that require the same parameter token, and these test cases span .py scripts. Generally, the token only needs to be obtained once, and then all other test cases using the unittest framework will call this parameter. So how to implement it? Although there is […]
Why do curly braces lose their expansion function after they are assigned to variables?
Ask a question Today, Xiao Wang asked a script question. Xiao Wang asked: Why can’t this script scan out all ? ? Xiaohong said: What does the printed IP and port mean? Xiao Wang: In the script, the echo variable is printed normally. HuaGouAfter reading Xiao Wang’s answer, he said: ? ? Xiao Hong then […]
