Declaring Function Pointers: Function pointers are declared by specifying the return type and parameter types they point to. For example, to declare a function pointer to a function that takes an integer and returns a float, you would use float (*funcPtr)(int). Assigning Function Addresses: Fu...

By using GCC, C, and C++ compilers the code will be generated, and assertions are enabled by default. If we are unable to use the assert() function, we must be disabled, so ndebug should be defined. It was decided to declare it using #define NDEBUG code; otherwise, the code compilatio...
