how would you do it if you were making change in real life?

mzxsuOP•9mo ago

What do you mean this might sound stupid but id legit just use a calculator

you need to subtract the double by the highest currency value (starting from $1 [1.0], down to $0.01 [.01])

    static void PrintExactChange(double change)
    {
        change = Math.Max(change, 0);

        int dollars = (int)change;
        change -= dollars;

        int quarters = 0;
        while (change >= 0.25)
        {
            change -= 0.25;
            quarters++;
        }

        int dimes = 0;
        while (change >= 0.10)
        {
            change -= 0.10;
            dimes++;
        }

        int nickels = 0;
        while (change >= 0.05)
        {
            change -= 0.05;
            nickels++;
        }

        int pennies = (int)(change * 100);

        Console.WriteLine($"Your change was {dollars} dollars, {quarters} quarters, {dimes} dimes, {nickels} nickels, and {pennies} pennies");
    }

    static void PrintExactChange(double change)
    {
        change = Math.Max(change, 0);

        int dollars = (int)change;
        change -= dollars;

        int quarters = 0;
        while (change >= 0.25)
        {
            change -= 0.25;
            quarters++;
        }

        int dimes = 0;
        while (change >= 0.10)
        {
            change -= 0.10;
            dimes++;
        }

        int nickels = 0;
        while (change >= 0.05)
        {
            change -= 0.05;
            nickels++;
        }

        int pennies = (int)(change * 100);

        Console.WriteLine($"Your change was {dollars} dollars, {quarters} quarters, {dimes} dimes, {nickels} nickels, and {pennies} pennies");
    }

goat also int oneDollars = 0; while (change >= 1) { change -= 1; oneDollars++; what excatly does this bit do?

oke•9mo ago

while the change amount is greater than or equal to 1.0, take $1 away from change and increment the dollar amount by one so: dollars = 0 change = 43.32 after one loop, it becomes: dollars = 1 change = 42.32 the same for all other amounts so: twentyCents = 0 change = 13.60 after one loop becomes: twentyCents = .20 change = 13.40

mzxsuOP•9mo ago

ohhhhh i see thank you

@mzxsu I know you closed it, but I honestly wouldn't use any kind of loop for that if I were you. (And take that as a lesson of "Because something works doesn't mean it's the right solution.")

oke•9mo ago

he didnt close it and i just did it for simplicity's sake if you got something else, please share

Yawnder•9mo ago

Yes, he did.

oke•9mo ago

that was me, telling how how to close it

Yawnder•9mo ago

Oh. Well I'm wrong! Sorry But before I'll elaborate on how, I'll see if they're still around.

oke•9mo ago

its okay any word starting with '$' is a command for info and you can tell if the thread is closed because the title will have a ✅ in front of it

mzxsuOP•9mo ago

oh i see ok got it $close
