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;
}

Wait, you can use
man
on C functions?On libc functions yes. Maybe on some from other libs, if they provide man pages.
That’s nice.
Yup! Try also
man malloc
😁Nice :)
Back in my day, MS-DOS let you use
HELP
on QBASIC commands.You can if you have those man pages installed.
