- Q2. How do you do range based map iteration
- Ans.
Range based map iteration can be done using a for-each loop or iterators.
Use a for-each loop to iterate over the map elements.
Alternatively, use iterators to traverse the map.
The range-based for loop is preferred for its simplicity and readability.
Example: for(auto const& [key, value] : myMap) { //do something with key and value }
- Q3. What are detached and joined threads
- Ans.
Detached threads are independent threads that run separately from the main thread. Joined threads are threads that wait for the main thread to finish.
Detached threads are created using pthread_detach() function
Joined threads are created using pthread_join() function
Detached threads do not need to be explicitly terminated
Joined threads must be explicitly terminated using pthread_exit() or return statement
Detached thread...
- Q4. What are static code analysis tools
- Ans.
Static code analysis tools are software programs that analyze source code to find potential issues and improve code quality.
Static code analysis tools scan code without executing it
They can detect issues such as security vulnerabilities, coding errors, and performance problems
Examples of static code analysis tools include SonarQube, ESLint, and Checkstyle
- Q5. Command to list currently running threads in linux
- Ans.
Command to list currently running threads in linux
Use the 'ps' command with the 'H' option to display threads in a hierarchy
Use the 'top' command to display threads in real-time
Use the 'htop' command for an interactive display of threads
- Q6. Can we perform arithmetic operation on Unique pointer
- Ans.
No, arithmetic operations cannot be performed on unique pointers.
