void x1(int *) A function which has int * argument and return type void.void (*x2)(int *) Pointer to a function which has int * argument and return type void.void (*x3())(int *) A function that returns a pointer to a function which has int * argument and return type void.void (*x4(void (*)(int *)))(int *) A function which has a pointer to a function that has int * argument and return type void as argument, and returns a pointer to a function which has int * argument and return type void.void (*x5(void (*[10])(int *)))(int *) A function which has an array of 10 pointers to functions that has int * argument and return type void as argument, and returns a pointer to a function which has int * argument and return type void.void (*(*x6)(void (*[10])(int *)))(int *) A pointer to a function which has an array of 10 pointers to functions that has int * argument and return type void as argument, and returns a pointer to a function which has int * argument and return type void.char (*(*x7())[])() Function returning pointer to array[] of pointer to function returning char.char (*(*x8[3])())[5] Array[3] of pointer to function returning pointer to array[5] of char.
