What would be the best solution for this problem?? if we have a question say by the pythagoran theorem. x^2+ y^2 = c then according to that if we are given the value of c, what shall be the best way to deal and find the values of x and y? x and y can be negative. Also, suppose c=0 then x=0 and y=0. Moreover, if we have c=1 then we hav...

I have a program that contains the following piece of code for constructing an array of asterisks: char array[Length][Height]; for (int count1 = 1; count1 <= Length; count1++) { for (int count2 = 1; count2 <= Height; count2++) { strcpy(array[count2][count3], "*"); cout << array[count2][count3]; } } cout << e...
I'm given a list of arcs: arc(a,b). arc(b,c). arc(c,d). arc(d,b). arc(d,e). arc(e,e). arc(e,f). I've written a set of clauses which will tell me if theres a path from node X to node Y. Loops may occur and I've accounted for that. path(X,Y) :- arc(X,Y). path(X,Y) :- arc(X,Z), path(Z,Y,[X]). path(X,Y,P) :- arc(X,Y). path(X,Y,...
