举一反三
- 下面程序的输出是______ void apple(int *x) {printf("%d\n",++*x); } main() {int a=25; apple(&a); } A: 23 B: 24 C: 25 D: 26
- 对于字符串和for循环的知识点，现设置代码如下：[img=413x259]17da6f9eb7df542.png[/img]请分析这段代码的输出结果为（ ）。 A: {'grape': '1',apple': '2','watermelon': '3','lemon': '4'} B: {grape:1,apple:2,watermelon:3,lemon:4} C: ['grape';'1', 'apple':12', 'watermelon';'3','lemon';'4'] D: [grape:1,apple:2,watermelon:3,lemon:4]
- 若有语句：int *apple,a=4;和apple=&a;下面均代表地址的一组选项是______ A: a，apple,*&a B: &*a,&a,*apple C: *&apple,*apple,&a D: &a,&*apple,apple
- 以下关于Python自带数据结构的运算结果中正确的是哪一项？ A: l = [1, 2, 3, 4, 5]; del l[2:4]; 则运算之后l为[1, 2, 3]。 B: l = [2, 1, 3, 5, 4]; l.remove(3); l.sort(); 则运算之后l为[1, 2, 4, 5]。 C: basket = ['apple', 'banana', 'apple', 'orange'] ; fruit = set(basket); len(fruit) 的运算结果是4。 D: basket = ['apple', 'banana', 'apple', 'orange'] ; fruit = set(basket); fruit2 = set(['apple', 'melo']); len(fruit | fruit2) 的结果是5。
- 阅读以下程序，填写运行结果________________.dic={'apple':2, 'orange':5, 'pear':3, 'banana':6, 'watermelon':1}n=0for k,v in dic.items(): if v>=n: m=k n=vprint(m)
