Question

嗨，我有问题，C++

#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 << "\n\n"; 
    else 
    cout <<"\ndivisior does not equal 0!\n\n"; 

    system("PAUSE");  
    return 0; 
} 

我必须使用或同时，当有人通过0

Answer 1

尽量商数量如果我理解正确的话，你可能要问的输入如果再b为零

你可以有这样的事情：

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 << "\n\n"; 
    else 
    cout <<"\ndivisior does not equal 0!\n\n"; 
}while(b==0); 

Answer 2

你的T erms是错误的，请参阅Wikipedia definition of "quotient"。

#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; 
}
