[Solved] Sum of LCM range from 1 to 10^9 [closed]

by

[ad_1] // In pseudocode a very basic algorithm: main for i: 1 to 1000000000 if (TestValue(i)) Output(i) TestValue(i) for j: 1 to 99 if j does not divide i evenly return false return true Of course, this won’t be very performant. You might notice that if a number is evenly divisible by all numbers between … Read more

[Solved] Simplifying a class with similar classes inside [closed]

by

[ad_1] You could create an Animal base class. You’ll probably want to make it abstract so the only way to instantiate an Animal is by creating a new derived object. abstract class Animal { public abstract int Rarity { get; } // Abstract properties must be implemented by derived classes public int Amount { get; … Read more

[Solved] Error: invalid types ‘int [200][float]’ for array subscript

by

[ad_1] So from the comments: if col is float col[H][W];, your trying to index vx/vy via a float. You would have to cast to int again: int vx2 = vx[static_cast<int>(col[iposy][iposx])]; int vy2 = vy[static_cast<int>(col[iposy][iposx])]; Be careful: There is no implicit index checking, so if your floats are out of range (negative or > WIDTH/HEIGHT), you … Read more

[Solved] Given a positive integer N as input, how do I find the product of the numbers in their subsets?

by

[ad_1] Well, there is a very easy and naive recursive solution to retrieving all subsets. You take away one element from your set, then find all subsets for this new, smaller set. Then you copy the result and add the element you previously removed to the copy. Add the results together and you’re done. For … Read more

[Solved] What is the type for structure and pointers?

by

[ad_1] The possible types as, x1 = c->buf; x1 is pointer to a character since buf is the base pointer. x2 = *c->buf; x2 is a character since base pointer is dereferenced to get the first character x3 = &c->buf[c->curp]; x3 is a pointer to a character since c->buf[c->curp] gives a character and & gives … Read more

[Solved] While (true) loop lagg [closed]

by

[ad_1] while(true) is an infinite loop, the only way of getting out of it is using break. Or changing while(true) to some condition that alternatively ends. In this code, the while(true) part makes no real sense to me, you should probably add something else to that part as well, e.g. some connection stuff etc. 6 … Read more

[Solved] Use of execl (Arguments)

by

[ad_1] All the arguments to execle() except the last two are strings — the penultimate one is a null char * marking the end of the command line arguments, and the last is a char ** specifying the environment. The first is the pathname of the executable, relative to the current directory if the name … Read more
