supported by VC, GCC, and other compilers. However, in UNIX and Linux, Longlong and % LLD are required. The latter is standard C!
I tried Longlong with % i64d, which can be output correctly, but neither Longlong nor _ int64 with % LLD can be output correctly. So I come to the conclusion that Longlong or ,__ int64 must be used with DD in windows. In UNIX and Linux, the standard C Longlong must be used in combination with % LLD.

Oracle 10 GB Data migration across tablespaces
Because some developers do not have in-depth understanding of the Oracle database, they usually specify non-default tablespaces when creating tables, this causes many problems during operations such as exp and imp. Therefore, you need to migrate these tables and related data back to the default tablespac

As we all know, arrays of the Object type can be stored at all times, but it is often troublesome to retrieve them. If the same type of data is stored in the array, everyone knows how to fetch the data. This is not a problem, but if you have such a requirement, you have to consider how to obtain the data in a loop:
------------------------------------------------
1. templates can be used for data types, such as C ++, which is relatively simple, but C is difficult.
2. If there is no data type, it is necessary to judge all points for execution. Time is complex and time is not optimized, and the code is easy to understand. For example, test the right triangle.
VaR Epsilon = 0.00000000001; // small numbers to be tested.
