int three=3;
char one=‘1’
char four=(char)(three+one);
举一反三
- 下列语句片断中，four的值为（）。 Int three=3; Char one=’1’ Char four=(char)(three+one);
- 纽约步的节拍是（ ） 。 A: two and three and four one B: one two three four and one C: one two three four D: two and three four one
- 以下语句的执行结果是什么？console.log('one');setTimeout(function(){ console.log('two');},0);console.log('three');console.log('four'); A: “one” “three” “four” “two” B: “one”“two” “three” “four” C: 不确定 D: 以上都不对
- 下列程序的输出结果是（ ）a=1;switch a case 0&1 disp（'one'） case {1，2} disp（'two'） case 3 disp（'three'） otherwise disp（'four'）end。 A: four B: three C: two D: one
- 下列程序的输出结果是（ ）a=1;switch a case 01 disp('one') case {1,2} disp('two') case 3 disp('three') otherwise disp('four')end A: one B: two C: three D: four
