This is the paint cost question. I'm getting the first two test right but others are wrong. What is wrong in the code?

Question

#include <iostream>
using namespace std;

int main() {
int canvas = 40;
int number;
int paint ;
float sum ;
float tax ;
float total ;

cin >> number ;
paint = number * 5 ;
sum = paint + canvas ;
tax = sum / 10;
total = sum + tax ;
cout << total ;

return 0;
}

Answer 1

To round upward there is a function called "ceil()" [ceiling] in the math library.

#include <math.h>
...
total = ceil(sum + tax);

However, merely using ceil() is not sufficient. I found that I also had to cast the result to integer on output in order to pass the fifth test.

cout << (int)total;

Answer 2

Brian okay, thanks a lot!!

Answer 3

The instructions require the output rounded up to the nearest dollar.

Answer 4

Brian how do I that? Round () ??
