How do I interface C++ with C APIs (extern "C")?

Interfacing C++ with C APIs is straightforward thanks to the ability to use `extern "C"` in C++. This allows C++ to call functions defined in C without name mangling issues, enabling seamless integration of libraries written in C. Below is a simple example demonstrating how to use C APIs in C++ code.

        
extern "C" {
    #include "your_c_api.h" // Include your C header file
}

#include 

int main() {
    // Call a C function defined in your C API
    int result = c_function_name(42); // assuming c_function_name exists in your C API
    std::cout << "Result from C function: " << result << std::endl;
    return 0;
}
