What am I doing wrong. It’s about Halloween candy practice.

Question

#include <iostream>
#include <cmath>
using namespace std;

int main() {
int houses;
int dollar = 2;
int chances;
cin>>houses;
chances = dollar*100/houses;

cout << chances;

return 0;
}

Answer 1

You could use the % operator to check if the result is a decimal.

If it is a decimal, you round up to the next integer.

round up & round are 2 different meanings.

#include <iostream>
#include <cmath>
using namespace std;

int main() {
int houses;
int dollar = 2;
int chances;
cin>>houses;
chances = dollar*100/houses;

if((dollar*100) %houses==0){
cout << chances;
} else {
cout << chances +1;
}
return 0;
}

Answer 2

You have to roundup the value see input and output format

Answer 3

ceil(dollar*100.0/houses)

Answer 4

Thanks a lot. I understood both methods.

Answer 5

Still not working. I get the same error.

#include <iostream>
#include <cmath>
using namespace std;

int main() {
int houses;
int dollar = 2;
double chances;
int result;
cin>>houses;
chances = dollar*100/houses;
result = round(chances);

cout << result;

return 0;
}
