Suppose I have a data set called DATA and want to extract rows 1 to 10 and columns 5 to 7. What would be the relevant R command? A: DATA[1:10,5:7] B: DATA[5:7,1:10] C: DATA[10:1,7:5] D: DATA[7:5,10:1]

表示“整数data大于等于5,且小于8”的表达式________。

以下哪个不是Android手机常见的应用程序？（ ） A: \data\data\com.tencent.mm B: \data\data\com.tencent.mobileqq C: \data\data\com.eg.android.AlipayGphone D: \data\data\com.tencent.xin

下面为C语言程序，边界值问题可以定位在。 int data（3）,int i,for (i=1,i<=3,i++) data(i)= 5

已知有n个数据进行排序，下面能实现排序的是 A: data=[34,5,-6,12,87,29]data.sort() B: data=[34,5,-6,12,87,29]n=len(data)od=[]whileiwhilejifdata[j]>data[j+1]:t=data[j]data[j]=data[j+1]data[j+1]=tj+=1i+=1 C: data=[34,5,-6,12,87,29]n=len(data)i=0j=0whileiwhilejifdata[j]>data[j+1]:t=data[j]data[j]=data[j+1]data[j+1]=tj+=1i+=1print(data) D: data=[34,5,-6,12,87,29]n=len(data)i=0j=0whileiwhilejifdata[i]>data[j]:t=data[i]data[i]=data[j]data[j]=tj+=1i+=1

有如下程序 #include intchange(int*data) { *data=*data%2; return(*data)+1; } main() { intdata=12; change(&data); printf("%d,",data); data=change(&data); printf("%d,",data); } 程序运行后的输出结果是()

The data collected by the statistical survey can be original data or secondary data. The relationship between the original data and secondary data is ( ) A: The original data comes from the grass-roots units, and the secondary data comes from the superior units B: Secondary data is processed from original data C: There is no necessary connection between the original data and the secondary data D: There is no difference between primary data and secondary data

若有以下说明和定义: union dt { int a; char b; double c;}data; 以下叙述中错误的是( )。 A: data的每个成员起始地址都相同 B: data中起作用的是最后一次存放的成员 C: 可以直接对变量data赋值，data={5, 'A', 3.6}; D: 变量data 所占内存字节数与成员c 所占字节数相等

What is stored in the database is（ ）. A: data B: data mode C: links between data D: data and the connection between data

有如下程序 #include int test(int *data) { return --(*data); } main() { int data = 12; test(&data); printf("%d,", data); data = test(&data); printf("%d,", data); } 程序运行后的输出结果是
