Random char (a-z) withouth repeats

[dualdark]

Hi guys, im doing a game, which needs to repeat at least 26 times, once for each letter of the abc, which needs to be random every time.

I got this, but is not working, it gives me random char, but they are repeating...

this is my code..

srand(time(NULL));
        var.letra = 97 + rand()%(122-97);

        for(i=0;i<27;i++){
            while(var.temp[i] == var.letra){
                var.letra= 97 + rand()%(122-97);
            }
        }
        for(i=0;i<=partidas;i++){
            if(i==partidas){
            var.temp[i] = var.letra;
            }
        }

thanks in advance

Save all letters to the array, shuffle it and just take letters in order.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16

#include <algorithm> #include <array> #include <iostream> #include <numeric> int main() { std::array<char, 26> letters; std::iota(letters.begin(), letters.end(), 'a'); for(char c: letters) //Array before shuffling std::cout << c; std::cout << '\n'; std::random_shuffle(letters.begin(), letters.end()); for(char c: letters) //After shuffling std::cout << c; }

	string x = "abcdefghijklmnopqrstuvwxyz";
	int inc = 26;
	while (1){

		if (inc < 1){
			cout << "end of blah blah";
			break;
		}
		int Number = rand() % inc + 0;
		cout << x.at(Number) << endl;

		
		string x2 = "";
		for (const auto c : x){

			if (c != x.at(Number)){

				x2.push_back(c);
			}
		}

		x = x2;
		--inc;
	}
