Ask the right questions to secure the right C1X talent among an increasingly shrinking pool of talent.
C1X is a version of the C programming language standard that was published in 2011. It is an informal name for ISO/IEC 9899:2011, a standard promulgated by ISO (International Organization for Standardization) and IEC (International Electrotechnical Commission). This version introduced several new features to the language, including multi-threading support, improved Unicode support, and new libraries for complex mathematical operations. It also included several improvements to the language's syntax and semantics to make it easier to write and understand code. C1X is backward compatible with previous versions of the C standard, meaning that code written in older versions of C can be compiled and run using a C1X compiler.
The next 20 minutes of the interview should attempt to focus more specifically on the development questions used, and the level of depth and skill the engineer possesses.
Multithreading in C1X can be implemented using the '_Thread_local' keyword to declare thread-local variables, and the 'thrd_create' function to create a new thread.
Multithreading support allows for concurrent execution of two or more parts of a program for maximum utilization of CPU.
C1X introduced several new features and improvements over previous versions, including multithreading support, improved Unicode support, and new library functions.
The 'quick exit' function can be used to terminate a program without completely cleaning the resources, which can be useful in situations where performance is a priority over cleanup.
C1X includes features like multithreading support, improved Unicode support, bounds checking interfaces, a new 'quick exit' function, and more.
This is important as it shows the candidate's ability to work in a structured and systematic way.
This is crucial as technology is constantly evolving and the candidate needs to be able to keep up with the changes.
This is important as it shows the candidate's ability to handle complex projects and work under pressure.
Good communication skills are essential for teamwork and for explaining complex concepts to non-technical stakeholders.
This is crucial as it indicates the candidate's ability to think critically and solve complex problems.
This is important as it shows the candidate's ability to use the language effectively and efficiently.
The next 20 minutes of the interview should attempt to focus more specifically on the development questions used, and the level of depth and skill the engineer possesses.
Unicode support in C1X can be used by including the 'uchar.h' header and using the 'char16_t' and 'char32_t' types for Unicode characters and strings.
Improved Unicode support allows for better handling of international text, making it easier to develop software for global markets.
While both functions terminate the program, 'exit' performs complete cleanup of resources, while 'quick_exit' does not, which can make it faster in certain situations.
The 'aligned_alloc' function can be used to allocate a block of memory that is suitably aligned for any object type. The function takes two parameters: the alignment and the size of the memory to be allocated.
C1X introduced several new library functions, including 'aligned_alloc' for aligned memory allocation, 'quick_exit' for quick program termination, and 'thrd_create' for thread creation.
A skilled C1X engineer should demonstrate excellent knowledge of C1X programming, problem-solving abilities, and strong debugging skills. Red flags include lack of technical depth, inability to articulate past projects clearly or lack of enthusiasm for coding.

} The final few interview questions for a C1X candidate should typically focus on a combination of technical skills, personal goals, growth potential, team dynamics, and company culture.
Atomic operations in C1X can be used by including the 'stdatomic.h' header and using functions like 'atomic_load' and 'atomic_store' that perform operations on atomic types.
Atomic operations are operations that are performed as a single, unbroken unit without the possibility of interruption, which is important in multithreaded programming.
While both functions copy a string, 'strcpy_s' takes an additional size parameter and checks whether the data fits into the destination before it is copied, helping to prevent buffer overflow.
Bounds checking interfaces can be used by including the 'string.h' header and using functions like 'strcpy_s' and 'strcat_s' that take an additional size parameter.
Bounds checking interfaces are a set of functions that check whether the data fits into the destination before it is copied, helping to prevent buffer overflow.
