Test a volume

2. Right
4. Start System test Case design when requirements are complete
6. 6 (10-5+1) elements per line, 8 lines between [10,9] and [18,9], [10,9] distance [10,5] 4 elements, total interval (8 x 6 +4) x4 (4 storage units) 1000 + 208 = 1028
8. The dead loop proves that there is a dynamic semantic error
10. Spiral Model integrated waterfall model and evolutionary model, and increased risk analysis
12. Doubly linked list: LIFO stack: Advanced back-out queue: FIFO first
14. Max heap/Minimum heap?? Think of data as a binary tree child node is always larger/smaller than the root node
16. Right
18. Binary search requires log (n) + 1 times
20. The stack is a linear table after the advanced
22. After P insert s the next pointer that needs S is pointing to P's next hand pointing to S
    S→next = P→next, P→next = s
24. The previous sequence traversal and subsequent traversal of the opposite two-tree is a single chain (only left dial hand or right cotyledons), the high end must be equal to the node count
26. If there is only one main function then the local variable is equal to the scope of the global variable
28. In C, you cannot make nested definitions of functions, you can make nested calls to functions
30. C, Char occupies a byte 256 is a 2^8 (100000000) overflow, so char c = n, int d = c, d = 0; if char c = 255, then 1
32. 3 x 4 x 4 = 48
34. a++ returns the value before increment so a++ = 0
36. Stream is not a standard input and output fellow
38. Java program will produce a byte code (bytecode), Java in the source code after the first compilation will generate the intermediate code is the bytecode, the JVM built-in interpreter interpretation of the execution of bytecode, generating machine code; C + + generates machine code directly after the first compilation of the source code
40. Do while at least once?? Do again check while condition
42. Priority: >< && | |
44. Right
46. Paradigm Paradigm
48. DBS contains DB and DBMS
50. Right
52. Right
54. The types of permissions are divided into Insert,delete and Updata three.
56. Right
58. Right
60. Right
62. The three main elements of software Engineering: tool process method; environment does not belong to
64. There are two types of improved soft landscape quality and reliable technology: error avoidance, fault tolerance
66. CMMI capability maturity, processes and requirements belong to defined levels
