int array[0] in standard C or C + + because an array of 0 lengths is not supported; Such a definition is illegal. However, some compiler extensions support a 0-length array. In C, the primary purpose of a 0-length array is to be used as the last member of the structure body, and then to use it to access a segment of

Very often when we create some view dynamically, we need to determine the layout of the other view by obtaining their width and height, but OnCreate () gets the width and height of the view to get 0.view.getwidth () and View.getheight () is the root cause of 0 because the control hasn't finished drawing yet, you have to wait for the system to finish drawing the view before you can get it. This situation occ

This function is used to compile a string of source code, the result can be generated bytecode or AST(like syntax tree), bytecode can be executed using function exec () , and AST can use eval () to continue compiling. The parameter source is the source of a string of strings, or An array of AST objects. The parameter filename is the file object that reads the string, and if it is not compiled from a file that reads the source code, you can put some strings to identify it. The parameter mode is

1. Basic Concepts 1.1 Software Software is a computer program that can run on a computer, such as operating system windows, Office software Office, chat QQ, mobile games, and so on. The link between software and our lives and work is getting closer. 1.2 Software Testing The classic definition of software testing is to operate the program under prescribed conditions to discover bugs, measure software quality, and evaluate whether it meets design requi

First, the difference between zeromemory and memset: 1. zeromemory is provided by Microsoft SDK, Memset is provided by C run-time library. Therefore, zeromemory can only be used in Windows systems, while memset can be used in other systems. 2. zeromemory is a macro.It is only used to set the content of a piece of memory to zero. It is actually implemented using memset internally. In addition to Resetting the memory, memset can also set the memo

We can see that do {...} While (0) is one of the advantages. Then there is the second macro. #define myswap(x, y) do{int temp = x; x = y; y = temp;}while(

test_func, $FUNCNAME = (test_func main) 5 out of function, $FUNCNAME =G T ()So, to be more precise, funcname is an array, but it is maintained in bash as a stack-like form. Another useful constant similar to funcname is Bash_source, which is also an array, but its first element is the name of the current script. This is useful when source, because in the script that is source, $ A is the name of the parent script, not the script name of the source. And Bash_source can be handy.1 # If the script
