商数程序帮助我

Quotient program help me

嗨，我对 c++ 有问题

#include <iostream>  
#include <cstdlib>  
using namespace std;  
int main(int argc, char *argv[])  
{  
  float a,b,wynik;  
  cout << "quotient" << endl   
       << "..." << endl << endl   
       << "quotient 2 numbers."  
       << "ndivisior does not equal 0"<< endl << endl;  
  cout << "a=";  
  cin >> a;  
  cout << "b=";  
  cin >> b;  

  if (b!=0)  
      cout << "n" << a << " / " << b << " = " << a/b << "nn";  
  else  
    cout <<"ndivisior does not equal 0!nn";  
  system("PAUSE");    
  return 0;  
}

当有人尝试将商数按 0 时，我必须使用 for 或 while。

如果我

理解正确，如果b为零，您可能想再次请求输入

你可以有这样的东西：

do {
  cout << "quotient" << endl   
       << "..." << endl << endl   
       << "quotient 2 numbers."  
       << "ndivisior does not equal 0"<< endl << endl;  
  cout << "a=";  
  cin >> a;  
  cout << "b=";  
  cin >> b;  
  if (b!=0)  
      cout << "n" << a << " / " << b << " = " << a/b << "nn";  
  else  
    cout <<"ndivisior does not equal 0!nn";  
}while(b==0);

你的术语是错误的，请参阅维基百科对"商"的定义。 

#include <iostream>
int main(void)
{
    char   prompt[] =
        "n"
        "Division, dividend / divisor = quotient:n"
        "    Enter divisior: ";
    int divisior;
    int dividend;
    while (true)
    {
        std::cout << prompt;
        std::cin >> divisor;
        if (divisor == 0)
        {
            std::cout << "n* Divisor is zero, try again.n";
            continue;
        }
        std::cout << "n    Enter dividend: ";
        std::cin >> dividend;
        std::cout << "nResult of "
                  << dividend
                  << " / "
                  << divisor
                  << " is, using integer division, "
                  << dividend / divisor
                  << "n";
        break;
    }
    return EXIT_SUCCESS;
}
