举一反三
- 已知x=7,y=11,表达式“(x>6||y<=10)”的值为()。 A: 0 B: false C: true D: 1
- 执行下列代码段后，b、x、y的值是（）。int x = 6, y = 8;boolean b;b = x ＜ y || ++x == –y; A: true、6、8 B: false、7、7 C: true、7、7 D: false、6、8
- It's called if a manafacturer achieves lower costs due to the enlarged production capacity of the whole industry. A: internal economies of scale B: externaleconomies of scale C: overlapping demand
- The representation of left-hand and right-hand cylindrical helical springs are the same. (True or false: 10 points)
- 下列Python程序的运行结果是（ ）。 x=0 y=True print(x>y and 'A' A: True B: False C: true D: false
