User input looping and adding all inputs-CodePudding

I needed to get the total of all the user's input products but I can't do it. I need to ask the user to choose the product and its quantity and then ask the user if she would like to add more products or pay it. The user will enter product again and its quantity. After it the program will ask again if add or pay. When the user choose pay it was supposed to output the total amount of products. Then lastly the program will ask the user if she/he would like to use the program again, if not, it'll exit.

int choice, quanti, decide, total, price;
string w = "WELCOME ";
Console.SetCursorPosition((Console.WindowWidth - w.Length) / 2, Console.CursorTop);  // for setting string output on center top
Console.WriteLine(w);
Console.WriteLine("");
System.Threading.Thread.Sleep(2000); //time delay

string p = "HERE'S OUR MERCHANDISES! ";
Console.SetCursorPosition((Console.WindowWidth - p.Length) / 2, Console.CursorTop);  // for setting string output on center top
Console.WriteLine(p);
System.Threading.Thread.Sleep(2000);//time delay

string[] products = { "[1]BLACKPINK Lightstick ", "[2]DREAMCATCHER Seasons Greetings", 
                        "[3]RED VELVET Summer Package"};

for (int g = 0; g < products.Length; g  )
{
    Console.WriteLine(products[g]);
}

for (int i = 0; i < products.Length; i  )

    choice = int.Parse(Console.ReadLine());
