Complete Modern C++ - Function Pointers

The video tutorial explains function pointers in C programming, detailing their declaration, usage, and advantages. It covers how function pointers can be used to invoke functions indirectly, matching the function's signature. The tutorial also demonstrates using function pointers with C library functions like 'at exit' to execute code before program termination. The video concludes with a brief mention of namespaces, which will be covered in the next video.
