笔试面试 下面代码执行后的结果是( ) #!/usr/bin/python3 import re string = “Cats are smarter than dogs” ret = re.search( r'(.*) are (.*?) .*’, string, re.M|re.I) if ret: print (“ret:”, ret.group(2)) else: print (“Nothing found!!”)
笔试面试 请为横线处选择合适的程序,使得程序的运行结果是1 2( ) class B { public: B(int a):i(a){} int p1(){return i;} private: int i; }; class D:public B { public: D(int a,int b): {} void p2(){cout<<B::p1()<<” “<<d;} private: int d; }; int main() { D d1(1,2); d1.p2( ); return 0; }
