问题描述
我正在开发一个从文本文件中获取点 2D、点 3D、line3D 和 line3D 数字的程序。然后,该文本文件将通过程序运行,其中的数据可以根据用户的偏好进行排序。到目前为止,除了在输入无效输入时菜单不断反复循环这一事实之外,该程序没有任何问题。任何帮助将不胜感激。
int displayMainMenu(string f,string sC,string sO)
{
int choice;
cout << endl << "NIL" << endl
<< "NIL" << endl
<< "--------------------------------------------" << endl
<< "Welcome to Program"
<< endl << endl
<< "1) \t Read in data" << endl
<< "2) \t Specify filtering criteria (current: " << f << ")" << endl
<< "3) \t Specify sorting criteria (current: " << sC << ")" << endl
<< "4) \t Specify sorting order (current: " << sO << ")" << endl
<< "5) \t View data" << endl
<< "6) \t Store data" << endl
<< "7) \t Quit" << endl
<< endl << "Please enter your choice: ";
cin >> choice;
return choice;
}
int integerValidation(int option,string f,string sO)
{
switch (option)
{
case 1:
case 2:
case 3:
case 4:
case 5:
case 6:
case 7: return option;
default: do
{
cout << endl << "You have entered an invalid menu option. Please re-enter..."
<< endl;
option = displayMainMenu(f,sC,sO);
} while ((option != 1) || (option != 2) || (option != 3) ||
(option != 4) || (option != 5) || (option != 6) || (option != 7));
}
return option;
}
