For example, consider the following C program where wrapper() receives a void fun() as parameter and calls the passed function. ,You can only assign the addresses of functions with the same return type and same argument types and no of arguments to a single function pointer array. You can also pass arguments like below if all the above functions are having the same number of argume, The type of a function pointer is just like the function declaration, but with ...
