What are the two steps of a process execution? A: I/O & OS Burst B: CPU & I/O Burst C: Memory & I/O Burst D: OS & Memory Burst

若int a,b; double x;以下不合法的scanf函数调用语句是 。 A: scanf(“%d%o%f”, &a,&b,&x); B: scanf(“%3d%*3d%lf”,&a,&b,&x); C: scanf(“%o%f%lo”,&a,&b); D: scanf(“%ld%lo%o”,&a,&b,&x);

若int x，y; double z; 以下不合法的scanf函数调用语句是（ ） A: scanf("%d%lx%le", &x,&y,&z); B: scanf("%2d%d%lf", &x,&y,&z); C: scanf("%x%*d%o", &x,&y); D: scanf("%x%o%7.2lf", &x,&y,&z);

若int x,y; double z;以下不合法的scanf函数调用语句是( )。 A: scanf("%d%x,%le",&x,&y,&z); B: scanf("%2d*%d%lf",&x,&y,&z); C: scanf("%x%*d%o",&x,&y); D: scanf("%x%o%6.2f", &x,&y,&z);

已知：int x，y；double z；则以下语句中错误的函数调用是____ A: scanf ("%2d%d%lf",&x,&y,&z) B: scanf ("%x%o%6.2f",&x,&y,&z) C: scanf ("%d,%lx,%le",&x,&y,&z) D: scanf ("%x%*d%o",&x,&y)

若变量x,y均定义为int型,z定义为double型,下列不合法的scanf语句是( ) A: scanf("%d%d%lf",&x,&y,&z); B: scanf("%d,%x,%lf",&x,&y,&z); C: scanf("%x,%o,%6.2f",&x,&y,&z); D: scanf("%x,%o",&x,&y);

()方法需要考察模块间的接口和各模块之间的联系。 A: & B: 21333;& C: 20803;& D: 27979;& E: 35797; F: & G: 38598;& H: 25104;& I: 27979;& J: 35797; K: & L: 30830;& M: 35748;& N: 27979;& O: 35797; P: & Q: 31995;& R: 32479;& S: 27979;& T: 35797;

一个模块把数值作为参数传送给另一个模块，这种耦合方式称为（ A: & B: 25968;& C: 25454;& D: 32806;& E: 21512; F: & G: 20844;& H: 20849;& I: 32806;& J: 21512; K: & L: 25511;& M: 21046;& N: 32806;& O: 21512; P: & Q: 26631;& R: 35760;& S: 32806;& T: 21512;

设3阶实对称矩阵\( A \)的秩为2，且\( {A^2} - A = O \) ，则\( A \)相似于（ ） A: \( \left( {\matrix{ 1 & {} & {} \cr {} & { - 1} & {} \cr {} & {} & 0 \cr } } \right) \) B: \( \left( {\matrix{ 1 & {} & {} \cr {} & 1 & {} \cr {} & {} & 0 \cr } } \right) \) C: \( \left( {\matrix{ { - 1} & {} & {} \cr {} & { - 1} & {} \cr {} & {} & 0 \cr } } \right) \) D: \( \left( {\matrix{ 1 & 1 & {} \cr {} & 1 & {} \cr {} & {} & 0 \cr } } \right) \)

执行以下代码,运行结果defsplit(s):returns.split("t")s="Happybirthdaytoyou!"print(split(s)) A: 运行出错 B: ["&quot","Happy&quot",null,"&quot","birthday&quot",null,"&quot","to&quot",null,"&quot","you!&quot"] C: ["Happybir","&nbsp","hday","&nbsp","oyou!"] D: ["Happy","&nbsp","bir","&nbsp","hday","&nbsp","o","&nbsp","you!"]
