In C language structure and union support a very important feature that is the bit field. The bit field allows the packing of data in a structure or union and prevents the wastage of memory. Note: The layout of the bit-fields is implementation-defined that is the reason a lot of people are avoiding the use […]

The compilation process is complicated but interesting in c language. If a program has multiple files then each file compiles individually and creates the object of each source file. The important role of linkers comes after the creation of object files. It performs two important task symbol resolution and relocation. The linker takes each object

In C language, memory is allocated at runtime using the memory management functions (calloc, malloc … etc.). The memory management functions are guaranteed that if the memory is allocated, it would be suitably aligned to any object which has the fundamental alignment. The fundamental alignment is less than or equal to the largest alignment that’s
