When developing in C or C++, macros defined with #define are powerful tools that can simplify code, improve readability, or enable conditional compilation - but they can also introduce subtle...

Loop vectorization is a powerful compiler optimization where repetitive operations (like array processing) are transformed into SIMD instructions. This allows the CPU to perform multiple operations in parallel using vector...
When working with low-level or resource-constrained applications - especially in embedded systems - understanding the stack usage of each function is crucial. Excessive or unexpected stack consumption can lead to...
Understanding how C or C++ code translates into assembly can provide valuable insight into performance optimization and low-level system behavior. This is particularly useful for developers interested in analyzing compiler...
The gcc and g++ compilers provide a wide range of options to control how code is compiled and optimized. Understanding these options is crucial for efficiently managing the build process...
When compiling C or C++ code, the compiler needs to locate the header files referenced in the source files using #include directives. These headers can come from the standard library...
When you're optimizing code for performance, especially in C or C++, using compiler options like -march=native can significantly boost speed by enabling all the SIMD instruction sets and CPU-specific optimizations...
When we usually compile a C or C++ program, we just run a single command like gcc main.c -o test, and we have an executable. The compiler doesn't magically transform...
When you're working with C or C++ and using macros (via #define), it can be helpful to see what the preprocessor is actually doing - especially when debugging tricky macro...
When working with C or C++ code, it can be helpful to know what macros (via #define) the gcc or g++ compiler defines automatically. These predefined macros give you insight...
