1. Implement the basic C language library functions:int Mystrlen (const char* str);//Gets the length of the string based on the first address of the incoming string; The return value is lengthint Mystrlen (const char* STR){if (str = = NULL)return

2. String designator, modify 6-1 idcheck.py script, so that it can detect the length of the identifier, and can identify the Python keyword, the latter requirement, you can use the keyword module (especially keyword.kwlist) to assist Source: ' This

Oracle Oracle Common Fool question 1000 question (vi) Author: ccbzzp There are a lot of things that can come up to you when you're using Oracle, especially for beginners, today I simply end it, and I want to give it to everyone and hope it helps!

194./* + ordered */ According to the order in which the table appears in from, ordered connects Oracle to the table in this order. For example: Select/* + ordered */a. col1, B. col2, C. col3 from Table1 A, Table2 B, Table3 c Where a. col1 = B. col1

201./* + NOCACHE (TABLE )*/When a full table scan is performed, the CACHE prompts that the retrieval block of the table can be placed in the nearest least recently used LRU list in the buffer CACHE.For example:SELECT/* + FULL (BSEMPMS) NOCAHE
