Please help!

Question

Hey guys
Please help I'm kinda still learning..
I could not solve the third and forth cases of this problem neither with python nor c++
Can anyone tell me what have I done wrong..
Thank you

Here is my code in python:

canvas = 40.00
color = 5.00
tax = 0.1

def cal(colors):
total = colors * color + canvas
taxes = total * tax
print(int(taxes + total))

colors = int(input())
cal(colors)

And in c++:

#include <iostream>
using namespace std;

int calculate(int colors){
float canvas = 40.00;
float color = 5.00;
float tax = 0.1;
int price = colors * color + canvas;
int taxes = price * tax;
return price + taxes;
}
int main() {
int colors;
cin >> colors;
int total = calculate(colors);

cout << total;
return 0;
}

Answer 1

if you check the description again in output format, notice "rounded up to the nearest whole number"

in c++, for example float 0.2 casted to int it'll rounded down to 0. but the answer need tobe rounded up.

here's the function you need

Answer 2

//C++ code
#include <iostream>
#include <cmath>
using namespace std;

int main() {
int colors;
cin >> colors;
double price = colors * 5 + 40;
double taxes = price * 0.1;
double total = price+taxes;
int t = round(total);
cout << t;
return 0;
}
