 10 {
 11     int carton_size, number_cartons, eggs_per_omelette, number_of_omelettes;
 12 /*This will tell you how many omelettes you can make*/
 13
 14    number_of_omelettes = carton_size * number_cartons / eggs_per_omelette;
 15    cout << "Welcome to the Egg Ordering Guide.n";
 16    cout << "How many eggs do you want per carton? (12, 18, or 25):n";
 17    cin >> carton_size;
 18    cout << "How many cartons?:n";
 19    cin >> number_cartons;
 20    cout << "How many eggs in an omelette? (2 or 3):n";
 21    cin >> eggs_per_omelette;
 22    cout << "You can make ";
 23    cout << number_of_omelettes;
 24    cout << " omelettes with this amount of eggs.n";
 25
 26    return 0;
 27 }
这是因为

您在获取此计算的输入变量之前计算number_of_omelettes。将该计算移动到输出之前

： 
...
number_of_omelettes = carton_size * number_cartons / eggs_per_omelette;
cout << "You can make " << number_of_omelettes << " omelettes with this amount of eggs.n";

另外，请注意，除法运算符/运算符在乘法运算符之前*，这可能会导致整数除法导致零。为避免这种情况，请使用括号强制将乘法放在除法之前：

number_of_omelettes = (carton_size * number_cartons) / eggs_per_omelette;
