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;
}

    And I don’t think it is reasonable to expect people to understand the basics.

    If we assumed everyone asking a question knows nothing at all of the surrounding topic, and responded at length addressing every related detail instead of what was asked, our answers would be tedious, and often annoying. It’s called overexplaining (among other things). It’s usually better to tailor the answer to the cues given by the person asking, and let them ask more questions if necessary.

    If they did, then they wouldn’t have asked.

    OP didn’t ask about the basics. They clearly know them already, as we can see from the language and specificity of their question. I was happy to answer and provide a link for deeper detail.

    But then someone else came along who apparently knew less than OP did, and decided express anger at me for not preemptively guessing and catering to their unstated special needs, in an answer that wasn’t intended for them in the first place. That was incredibly entitled and rude.
