Using function pointers as arguments for other functions has been discussed in the literature I've been reading.
How would you transmit a function by reference without using pointers, is the question I have.
I've been searching the Internet for the solution, but I haven't come up with a solid response.
I am aware that variables may be sent by reference using the syntax void funct(int& anInt);.
How would you proceed if the parameter was a reference to a function rather than a reference to a variable?
Additionally, how would you utilise a function body reference?
