could you plzz tell me what is wrong with my program ????? now before it becomes 11:oo thanxxx

#include <iostream>
#include <iomanip>
#include <cmath>
#include <fstream>

using namespace std;

int main() {

int miles;
int capacity;
int cookies;
int angle;
int choice;

ofstream file;
file.open("hanan-natouf.dat");

do {
cout

file << "2. Calories in cookies" << endl;

cout << endl

<< " calories." << endl;
file << "You consumed " << cookies * (300 / (40 / 10))

change the data types to double
1
2
3
4
 
double miles;
double capacity;
double cookies;
double angle;


BTW, we have different timezones LOL
