Oct 29, 2024 am 07:15 AMHow to Obtain the Version of libstdc Library Installed on a Linux Machine
To determine the version of libstdc library installed on a Linux system, there are several methods you can employ.
One method involves using the following command:
$ strings /usr/lib/libstdc++.so.6 | grep GLIBC
This command displays the GLIBC version associated with the libstdc .so.6 library, providing an indication of the library's version. However, this method is considered more heuristic and ad-hoc.
For a more precise approach, use the ldconfig command to query the library version:
$ /sbin/ldconfig -p | grep stdc++
This command lists all shared libraries installed on the system, including libstdc , and displays their compatible versions.
Additionally, for libstdc versions 3.4.0 and later, a list of compatible versions can be obtained by running:
$ strings /usr/lib/libstdc++.so.6 | grep LIBCXX
This command will display a list of symbols indicating supported GLIBCXX versions.
To determine the date stamp of the installed libstdc library, use a C program like the following:
<code class="cpp">#include <cstdio> int main(int argc, char* argv[]) { #ifdef __GLIBCPP__ std::printf("GLIBCPP: %d\n",__GLIBCPP__); #endif #ifdef __GLIBCXX__ std::printf("GLIBCXX: %d\n",__GLIBCXX__); #endif return 0; }</code>
Compile the program using g and execute it to display the date stamp:
$ g++ libdatestamp.cxx -o libdatestamp $ ./libdatestamp GLIBCXX: 20101208
Finally, a comprehensive table of libstdc versions and their corresponding datestamps can be found in the library's documentation.

Yes, function overloading is a polymorphic form in C, specifically compile-time polymorphism. 1. Function overload allows multiple functions with the same name but different parameter lists. 2. The compiler decides which function to call at compile time based on the provided parameters. 3. Unlike runtime polymorphism, function overloading has no extra overhead at runtime, and is simple to implement but less flexible.

C has two main polymorphic types: compile-time polymorphism and run-time polymorphism. 1. Compilation-time polymorphism is implemented through function overloading and templates, providing high efficiency but may lead to code bloating. 2. Runtime polymorphism is implemented through virtual functions and inheritance, providing flexibility but performance overhead.

Yes, polymorphisms in C are very useful. 1) It provides flexibility to allow easy addition of new types; 2) promotes code reuse and reduces duplication; 3) simplifies maintenance, making the code easier to expand and adapt to changes. Despite performance and memory management challenges, its advantages are particularly significant in complex systems.

Polymorphisms in C are divided into runtime polymorphisms and compile-time polymorphisms. 1. Runtime polymorphism is implemented through virtual functions, allowing the correct method to be called dynamically at runtime. 2. Compilation-time polymorphism is implemented through function overloading and templates, providing higher performance and flexibility.

People who study Python transfer to C The most direct confusion is: Why can't you write like Python? Because C, although the syntax is more complex, provides underlying control capabilities and performance advantages. 1. In terms of syntax structure, C uses curly braces {} instead of indentation to organize code blocks, and variable types must be explicitly declared; 2. In terms of type system and memory management, C does not have an automatic garbage collection mechanism, and needs to manually manage memory and pay attention to releasing resources. RAII technology can assist resource management; 3. In functions and class definitions, C needs to explicitly access modifiers, constructors and destructors, and supports advanced functions such as operator overloading; 4. In terms of standard libraries, STL provides powerful containers and algorithms, but needs to adapt to generic programming ideas; 5
