How many rows of piles are generally set up in freestyle skating competition? How many piles per row? A: row 5 and 25 B: rows 2 and 18 C: rows 1 and 30 D: rows 3 and 20

中国大学MOOC: @num = (3,5,2,1,4);@num = sort(@num);push(@num, (6,7,8,9));pop(@num);shift(@num);执行以上语句后，@num=？

关于属性的使用正确的是 A: private int num;public string Num{get{return num;} set{num=value;}} B: private int num;public int Num{get{return num;}set{num=value;}} C: private int num;public int Num{get{num=value;}set{return num;}} D: private int num;private int Num{get{return num;}set{num=value;}}

unsignedcharnum;num=0X98;num=num%10;num=num%10;num=?() A: 15 B: 8 C: 9 D: 2

3、描述“变量num取值范围为10--100或为负数”的逻辑表达式为（）。 A: ( num>;10 || num<;100 ) &amp;&amp; (num<;0 ) B: ( num>;10 || num<;100 ) || (num<;0 ) C: ( num>;10 &amp;&amp; num<;100 ) &amp;&amp; (num<;0 ) D: ( num>;10 &amp;&amp; num<;100 ) || (num<;0 )

num=float(input('输入一个数字：\n'))<br/>num=int(num)<br/>num=int((num+5)/2)<br/>num=num*2-5<br/>num=int(num%5)<br/>print(num)输入：14.5输出：______

有如下程序，输入一个int型的整数num，逆向输出其各位数字，同时求出其各位以及各位数字之和。 #include#includevoid main() { int num,sum=0,k,i=0; cin>;>;num; while(num>;0) { (1) ; cout<; A: k=num%10 num=num/10 B: num=num%10 k=num/10 C: num=num/10 k=num%10 D: k=num/10 num=num%10

@num = (3,5,2,1,4);@num = sort(@num);push(@num, (6,7,8,9));pop(@num);shift(@num);执行以上语句后，@num=？ A: (2,3,4,5,6,7,8) B: (3,5,2,1,4,6,7,8,9) C: (1,2,3,4,5,6,7,8,9) D: (1,2,3,4,5,6,7,8)

有下列程序： num=6 while num>0: num=num-2 print(num)
