Explanation:
<u>For SQL Server</u>
- Data Recovery: Data recovery is done well on SQL Server. It is achieved by the restoration method. Behind this, a sysadmin must reconstruct a collection of SQL backups throughout a restore series that is technically right as well as relevant.
- Data Security: There are several approvals as well as limits for accessing main data objects or databases. These data are accessed only by the approved clients.
- Concurrency Control: This is essentially synchronization of the evidence or information accessed by multiple users as well as from separate locations.
Concurrency or Competitiveness control becomes accomplished with SQL Server Portable, using locking to further improve security. The locking regulates how multiple individuals can simultaneously navigate & alter shared storage, without interfering with one another.
Answer:
<em>#include <iostream></em>
<em>using namespace std;</em>
<em>int main()</em>
<em>{</em>
<em> int myNewAge;</em>
<em> int myCurrentAge = 29;</em>
<em> int currentYear = 2020;</em>
<em> </em>
<em>myNewAge = myCurrentAge+(2050-currentYear);</em>
<em />
<em>cout<<"My Current Age is "<<myCurrentAge<<". I will be "<<myNewAge<<" in 2050"<<endl;</em>
<em> return 0;</em>
<em>}</em>
Explanation:
The program is written in C++ language as required. firstly, we declare the three variables:
<em> </em><em>int myNewAge;</em>
<em> int myCurrentAge = 29;</em>
<em> int currentYear = 2020;</em>
Then we calculate the new age as: <em>myNewAge = myCurrentAge+(2050-currentYear);</em>
Using multiple cout operators (<em> </em><<) we display the output nicely as required by the question with this statement
<em>cout<<"My Current Age is "<<myCurrentAge<<". I will be "<<myNewAge<<" in 2050"<<endl;</em>
