What is Type Qualifiers?
Type qualifiers add extra meaning to a variable's declaration beyond its basic type, telling the compiler how the variable can be used or how it might change. C provides four standard qualifiers: const, volatile, restrict, and _Atomic. They do not change how much memory a variable uses, but they do affect what optimizations the compiler is allowed to make and what guarantees the programmer gets.
