The large o sign (English: Big O notation) is a mathematical symbol used to describe the asymptotic behavior of a function. To be more precise,
It uses another (usually simpler) function to describe the asymptotic upper bound of a function's order of magnitude.
The definition of the large Omega symbol is similar to that of the big O symbol, but the main dif
In the day-to-day office, we may enter some of the less commonly used symbols, such as: the diameter of the symbol, because it is not commonly used symbols, so many people do not know how to play the diameter symbol. This office will come to teach you how to enter the diameter of the symbol input method, as well as in common Office software Word, Excel and other
Previously in the extern "C" usage details have already mentioned the concept of symbols, it is a compiler for variables and functions of a token, the compiler for C and C + + code in the production of symbols when the rules are not the same, symbols in addition to their own name differences, there are strong symbols and weak symbols of the points
Let's look at a simple piece of code first.
Copy Code code as follows:
* TEST.C * *
void Hello ();
int main ()

First of all, I said it was a tragedy, before I saw the programmer's ego-link, load and library. C has strong symbols, weak symbols, strong references, and weak references. When I saw the 3.5.5 Weak signs and strong symbols, I feel a little confused, so write this article, I hope to be able to communicate with the same feeling of friends also hope that the expert advice.
First, let's take a look at the book's definition of them.
Introduces the scenario: (1) in file A, the variable i (int i = 1
You must have symbolic information when using Microsoft tools to debug applications. Symbolic files are included in executable files and dynamic link libraries (DLL)The placeholder space of the function. In addition, the symbol file can also represent the function call roadmap that has reached the failure point. For example, you must have a symbol when dumping the call stack in the debugger.

Javascript has two ways of determining whether two values are equal.
Equality symbol
The equality symbol consists of two equals: = =Javascript is a weakly typed language. This means that the equality symbol will cast the type in order to compare two values.
Copy Code code as follows:
"" = = "0"//False
0 = ""//True
0 = "0"//True
False = = "false"

Objective:As an iOS development, I believe we will encounter similar to the "Duplicate symbol" program error. For many novice, may be a bit unprepared, because this type of error is generally not a code logic error, most of the time in the compilation process error caused, so relatively difficult to troubleshoot. In the last few days, I had this problem in the process of quoting two SDKs, and used different means to solve the problem. Today this artic

3.1 symbol table
The main purpose of a symbol table is to associate a key with a value. In this example, you can insert a key-value pair into the symbol table and then find the corresponding value from all the key-value pairs in the symbol table. To implement a symbol table
Recently in some platform transplantation, HP's PA-RISC is a relatively old platform, porting often encounter some strange problems:

O dependency with-aa.In case of any problems:Ld: unsatisfied symbol "dchpmonitor: getcpu (STD: vector Find the cause:[Abp_dev]/project/abp01/abp_dev/
There are many ways to implement a symbol table, and here are a few of them. Unordered (unsorted) array implementations In this case, you do not need to change the array, the operation is executed on this array. In the worst case, insert, search, delete time complexity is O (n). Sequential (sorted) array implementations In this case we have the sorted keyword and the corresponding value.
Store by keyword in an array
