Let's take a look at how the UCC compiler handles strings, as shown in 4.2.8.Figure 4.2.8 String StringLiteral Figure 4.2.8 the 1th to 11th row of HELLO.C has 5 strings, visible from line 15th to 20th, except for the "123456" that initializes the global array buf[], the UCC compiler names several other strings.

Unified Communication is not the same as unified Interaction
UC is continuously warming up, but can it solve the problem of communication disconnection? The new system must take UC further to support real unified interaction.
The use of unified communication and collaboration (UCC) or Unified Communication as a service (uCaaS) is expected to increase rapidly in the next few years, because these technologies can integrate multiple channels into a sin

Oracle uses a cursor to query a string that combines the names of all fields in a specified data table.
Application Scenario: refer to the Code for querying all field names of a data table on the Internet, and use a cursor to generate a list of field names separated by select commas (,) consisting of all field names and commas (,) of a specified table.
The query result is output as follows:
The field list string of the current data table TB_UD_USER is
