- 代码： 以下正确的说法是：（） A: buffer中所有的元素都具有初始值2。 B: buffer[1]、buffer[2]、buffer[3]的初始值是随机的。 C: buffer[1]、buffer[2]、buffer[3]的初始值是确定的，为0。 D: buffer[1]、buffer[2]、buffer[3]的初始值是确定的，但可能随编译器实现而变化。
- 在执行“LEA BX,BUFFER”指令时,是把( )。 A: BUFFER的内容èBX B: BUFFER的偏移量èBX C: BUFFER的段基值èBX D: BUFFER的内容èEA
- Which is the correct description of a pinned buffer in the database buffer cache（） A: The buffer is currently being accessed. B: The buffer is empty and has not been used. C: The contents of the buffer have changed and must be flushed to the disk by the DBWn process. D: The buffer is a candidate for immediate aging out and its contents are synchronized with the block contents on the disk.
- 下列（ ）语句可以实现取数据的个位。 A: buffer[0] = data/100 B: buffer[0] = data%100/10 C: buffer[0] = data%10 D: buffer[0] = data%1000
