int w = 0; void fun() { w++; printf("w = %d\n", w); } main() { int w = 5; w++; printf("w = %d\n", w); fun(); printf("w = %d\n", w); }

一组合电路有四个输入[w3，w2，w1，w0]=W及一个输出K，W为二数进位数字，其中w3为MSB[最高位元]﹔K=1若且为若W=[w3，w2，w1，w0]]为5或7的倍数。下列叙述何者错误？（） A: w=0，w=1，w=0，w=0时K=0 B: w=0，w=1，w=0，w=1时K=1 C: w=0，w=1，w=1，w=1时K=0 D: w=1，w=1，w=1，w=0时K=1

阅读以下程序，输出结果是： w=[] for i in range(1,20): if (i%5==0) and (i%7!=0): w.append(str(i)) print (w)

执行如下程序段后，w的值为【 】.int x,y,w;x=y=1;w=x+1||(y+=5) && 0;

下列程序的运行结果是（ ）。t = 0 while t < 5: print(t, " is less than 5") t = t + 1else: print(t, " is not less than 5") A: 0 is less than 51 is less than 52 is less than 53 is less than 54 is less than 55 is not less than 5 B: 1 is less than 52 is less than 53 is less than 54 is less than 55 is less than 55 is not less than 5 C: 0 is less than 51 is less than 52 is less than 53 is less than 54 is less than 5 D: 1 is less than 52 is less than 53 is less than 54 is less than 55 is less than 5
