Paint costs.

Question

https://sololearn.com/coach/22/?ref=app
Either 4/5 or 3/5.
Why can’t I get 5/5?
Any ideas?

Answer 1

int main() {
int canvas = 40;
int color = 5;

int colors;
cin >> colors;

int total = canvas + (colors*color);

double with_tax = total + (total*0.1);
//int with_tax = total + (total*0.1);

cout << int(round(with_tax))<< endl;

return 0;
}
Guys, we got him!
5/5.
Now I don’t care why this does work?😂

Answer 2

cout << int(round(with_tax))<< endl;

Answer 3

Can you please show your attempt.

Answer 4

#include <math.h>
And then
round(with_tax)

"Output Format
A number that represents the cost of your purchase rounded up to the nearest whole number."

Answer 5

What? But I just did ...
Could it be because you store it as a double? Try rounding first then storing it as int

Answer 6

int main() {
int canvas = 40;
int color = 5;

int colors;
cin >> colors;

int total = canvas + (colors*color);

//double with_tax2 = total + (total*0.1); (with this I am getting first two test correct)

int with_tax = total + (total*0.1);(with this, first two and fifth one is correct)

cout << with_tax<< endl;
(If I try to print with round(with_tax), I get first 4 tests correct.)
//cout<< with_tax2<<endl;

return 0;
}

#include <iostream>
#include<cmath>

using namespace std;

int main() {
int canvas = 40;
int color = 5;

int colors;
cin >> colors;

int total = canvas + (colors*color);

double with_tax = total + (total*0.1);
//int with_tax = total + (total*0.1);

cout << round(with_tax)<< endl;
//cout<< with_tax2<<endl;
return 0;
}
With some changes, it’s 4/5.
The first 4 tests passed.

Answer 8

5/5

Answer 9

#include <stdio.h>
#include<math.h>
int main() {
int x,r;
float c,y;
scanf("%d",&x);
c=(x*5)+40;
y=c+c/10;
r=round(y);
printf("%d",r);
return 0;
}
