Sorry for the maybe stupid question. I wanted to write a straightforward c++ code that takes the number of people and returns how many baking trays of 12 muffins I have to bake when everyone gets two muffins.
So I read in the number so people via cin in the variable "personen" and after that, I calculate the number of the baking trays (variable "bleche") via
int bleche = ceil(personen/6);
But my code doesn't seem to round up the number. For example if personen = 290, trays is 48 (and not 49).
Can someone tell me why?
Thanks!
#include <iostream>
#include <cmath>
using namespace std;
int main(){
int personen;
cout <<"Personen?";
cin >> personen;
int bleche = ceil(personen/6);
cout << "Sie muessen " << bleche << " Backbleche backen." << endl;
cout << bleche*12 - personen*2 << " Muffins bleiben zur freien Verwendung uebrig." << endl;
return 0;
}
