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;
}

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.
