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;
}

Please put your code between tripple backticks in a seperate line above an below your code. Single backticks are only for
inline code
like this.To answer your question, the
%.2f
means it should only print two digits after the decimal point.You can also use some other variations like this:
%2f
print the number at least 2 characters wide%5.2
print the number at least 5 characters wide with a precision of two digits after the decimal point%05.2
the same as above, but fill leading digits with zerosThis is just formatting, play a bit around with it and you will get it.
