int (*fp)(int) x; declares a pointer to a function of return type int, which takes one argument of type int. What you can achieve with this, is to create aliases to existing functions, such as int func(int p) { return p+1; } int (*fp)(int) x = func; You can then call func() using x. printf("%d", x(39)); // prints 40 Somewhat identical: https://code.sololearn.com/c7yvjIx5hWsw/?ref=app
