What is %.2f? Why is it not just %f? Is there some additional calculation happening? The half function already does all the calculations including splitting the bill, so I’m not sure what %.2f is. (Btw why is this code not formatting correctly in lemmy?)


#include 
#include 

float half(float bill, float tax, int tip);

int main(void)
{
    float bill_amount = get_float("Bill before tax and tip: ");
    float tax_percent = get_float("Sale Tax Percent: ");
    int tip_percent = get_int("Tip percent: ");

    printf("You will owe $%.2f each!\n", half(bill_amount, tax_percent, tip_percent));
}

// TODO: Complete the function
float half(float bill, float tax, int tip)
{
    bill += (bill * (tax / 100.0));
    bill += (bill * (tip / 100.0));

    bill /= 2;

    return bill;
}

    Which part of that is confusing to you? We can help make it easier to understand.

    Edit: Oh, this isn’t even OP.

        Its like if you see a dog, ask what it is and someone answers Canis lupus familiaris.

        …and gives you a link to the Wikipedia page about dogs.

        It’s not a good answer in the sense that they did not do the work of copying and rephrasing the content of the website they linked, you have to do some of the work yourself. But it’s a very thorough answer that gives you all the information you need about formatting. Including examples of pretty much exactly the question OP asked.

        I’m not looking for meta level criticism of this style of advice, I’m trying to ask OP what was confusing on this page and help them learn how to read this page specifically. I’m not saying OP should be able to understand this page. I’m not saying this style of advice is acceptable or not.

        Edit: Nevermind, I thought OP posted that comment.

      The confusion is you just provided sample code showing how "%.2f" works - you didn’t answer the question which was what does that sequence of characters actually mean? What does the % do. What does the . do. What does the 2 do. What does the f do.

      OP needs to know the answer to all of those.

        OP got the answer to those in another comment, I’m asking what part they need help understanding in this link. Also, I didn’t provide the link.

        Edit: Nevermind, I mistook the comment for being OP.
