this question has answer here: list of predicates in prolog 1 answer if have list of predicates in prolog [flies, swims] , how can build predicate conjunction of predicates in list, ie fliesandswims(x) :- flies(x), swims(x). ? alternatively, there better way of building predicate @ runtime without putting component predicates in list , building compound 1 them when needed? edit: turns out duplicate of list of predicates in prolog . had found answer, thought returned whether given atom matched every predicate in list. didn't realise can pass variable instead of atom , have return every case matches well. library(lambda) powerful, has cost. if think 'simpler better' (wrt debugging, specially...) consider call_unary_list([], _). call_unary_list([p|ps], x) :- call(p, x), call_unary_list(ps, x). let's compare performances: compar...

this question has answer here: pass reference / value in c++ 6 answers #include<iostream> using namespace std; void callbyreference (int &); //function prototype int main() { int num; //variable declaration cout<<"enter number"; cin>>num; callbyreference(num); //function definition cout<<"number after triple "<<num<<endl; return 0; } void callbyreference (int & cref) //funciton definition { cref=cref*cref*cref; } if passing address in cref address should multiplied thrice. how value multiplied thrice? you have reference variable argument, variable altered , not address itself. reference variable alias actual variable , changes made reflect in changes made original variable in case
