            求赞

            #核心代码
            木有开头
            int a;
            cin >> a;
            if (a< )
            {
            cout << " ";
            }
            if (a<  and a>= )
            大于等于  并且小于  的用
            {
            cout << "    ";
            }
            
            重要数据长腿跑了

              我哪错了 求解 #include <iostream> using namespace std; int main() { int A,B,C,D,E; cin>>A>>B>>C>>D>>E; if(A<10) { cout<<"A"; } if(B<20) { if(B>=10) { cout<<"B"; } } if(C<40) { if(C>=20) { cout<<"C"; } } if(D<50) { if(D>=40) { cout<<"D"; } } if(E<80) { if(E>=50) { cout<<"E"; } } return 0; }
