[CCF] 201612-2 工资计算

【思路】按照题意对初始工资S进行循环，计算缴税后工资，若与T相等则退出循环，输出结果。

 #include <iostream>
 #include <windows.h>
 using namespace std;
 int main()
 {
     int T;
     cin>>T;
     if(T < )
     {
         cout<<T<<endl;
         return ;
     }
     int x = ;      //扣的钱
     int S = ; //未缴税的工资
     int A = S - ;
     while(true)
     {
         if(A <= )
             x = A * 0.03;
         else if(A <= )
             x =  + (A - ) * 0.1;
         else if(A <= )
             x =  +  + (A - ) * 0.2;
         else if(A <= )
             x =  +  +  + (A - ) * 0.25;
         else if(A <= )
             x =  +  +  +  + (A - ) * 0.3;
         else if(A <= )
             x =  +  +  +  +  + (A - ) * 0.35;
         else
             x =  +  +  +  +  +  + (A - ) * 0.45;
         if(S == x + T)
             break;
         S = S - ;
         A = S - ;
     }
     cout<<S<<endl;
     return ;
 }
