举一反三
- 以下程序段实现的输出是()。for(i=0;i<;=9;i++)s[i]=i;for(i=9;i>;=0;i--)printf("%2d",s[i]);[/i][/i] A: 9 7 5 3 1 B: 1 3 5 7 9 C: 9 8 7 6 5 4 3 2 1 0 D: 0 1 2 3 4 5 6 7 8 9
- 产生并输出如下形式的方阵。 1 2 2 2 2 2 1 3 1 2 2 2 1 4 3 3 1 2 1 4 4 3 3 3 1 4 4 4 3 3 1 5 1 4 4 3 1 5 5 5 1 4 1 5 5 5 5 5 1 #include "stdio.h" int main() { int a[7][7],i,j; for(i=0;i<7;i++) for(j=0;j<7;j++) if( (1) || i+j==6) a[i][j]=1; else if ( (2) &&i+j<6) a[i][j]=2; else if (i>j&&i+j<6) a[i][j]=3; else if (i i==j ; j==i ii i+j>6; j+i>6; 6
- 下面代码的输出结果为( ) for i in range(1, 7): if i % 2 == 0: print(i, end=" ") A: 1 2 3 4 5 6 7 B: 1 2 3 4 5 6 C: 2 4 6 7 D: 2 4 6
- Public Sub Proc(a%( )) Static i% Do a(i) = a(i) + a(i + 1) i = i + 1 Loop While i < 2 End Sub Private Sub Command1_Click( ) Dim m%, i%, x%(10) For i = 0 To 4: x(i) = i + 1: Next i For i = 1 To 2: Call Proc(x): Next i For i = 0 To 4: Print x(i);: Next i End Sub A: 3 4 7 5 6 B: 3 5 7 4 5 C: 2 3 4 4 5 D: 4 5 6 7 8
- 下面程序运行后,输出结果是( )。#include ;main( ){ int a[10]={1,2,3,4,5,6},i,j; for(i=0;i { j=a[i];a[i]=a[5-i];a[5-i]=j;} for(i=0;i}[/i][/i] A: 1 5 4 3 2 6 B: 1 5 3 4 2 6 C: 6 5 4 3 2 1 D: 1 2 3 4 5 6
