举一反三
- 数组x中合法的数组元素表示为()。 A: x9 B: x[9] C: x(i+1) D: x{6}
- 使用数组x输出10个1-100之间的随机整数(包括1和100),下列命令中正确的是:( ) A: Dim x(9) As Integer For i = 1 To UBound(x) x(i) = Int(Rnd() * 100 + 1) Print x(i); Next B: Dim x(9) As Integer For i = 0 To UBound(x) x(i) = Rnd(10) Print x(i); Next C: Dim x(9) As Integer For i = 0 To UBound(x) x(i) = Int(Rnd() * 100 ) Print x(i); Next D: Dim x(9) As Integer For i = 0 To UBound(x) x(i) = Int(Rnd() * 100 + 1) Print x(i); Next
- 表示x是5的倍数或是9的倍数的逻辑表达式为 ____。 A: x \ 5 = 0 Or x \ 9 = 0 B: x \ 5 = 0 And x \ 9 = 0 C: x Mod 5 = 0 Or x Mod 9 = 0 D: x Mod 5 = 0 And x Mod 9 = 0
- 执行以下程序段后,a,b,c的值分别是()。inta,b=100,c,x=10,y=9;a=(--x==y++)?—x:++y;if(x9)b=x++;c=y; A: 9,9,9 B: 8,8,10 C: 9,10,9 D: 1,11,10
- 以4,9,1为为插值节点,求\(\sqrt x \)的lagrange的插值多项式 A: \( {2 \over {15}}(x - 9)(x - 1) + {3 \over {40}}(x - 4)(x - 1) + {1 \over {24}}(x - 4)(x - 9)\) B: \( - {2 \over {15}}(x - 9)(x - 1) + {3 \over {40}}(x - 4)(x - 1) + {1 \over {24}}(x - 4)(x - 9)\) C: \( - {2 \over {15}}(x - 9)(x - 1) + {3 \over {40}}(x - 4)(x +1) + {1 \over {24}}(x - 4)(x - 9)\) D: \( - {2 \over {15}}(x - 9)(x - 1) + {3 \over {40}}(x - 4)(x - 1) - {1 \over {24}}(x - 4)(x - 9)\)
