y recent C++ 10-Minute Solution titled “Using a Good Parasite Class to Design a Self-Clearing Memory Buffer” was greeted with skepticism, raised eyebrows, and a torrent of questions from readers
++ constructs such as functions, types, variables, and blocks are associated with implicit properties that you sometimes need to override. Certain constructs require you to specify their unusual properties, for
f you’ve been programming in C++ for any time at all then you’re familiar with variadic functions, functions (such as printf) that can take a variable number of arguments. C99
any applications use a loop that fills a raw memory buffer with data, processes that data, and then clears that buffer before the next iteration. Standard containers such as vectoraren’t
previous 10-Minute Solution demonstrated the new initialization rules of C++09, which enable you to initialize standard containers (among the rest) in the following manner: vector scores = {89, 76, 98,
xplicit typecasting is considered are an abomination in object-oriented programming. However, prudery won’t change the fact that casts are still a widely-used feature in C++ programming. Therefore, knowing exactly which
tandard C++ offers a rather limited number of functions for accurate time measurement: clock() gives you a granularity of up to a thousandth of a second at best, and difftime()
ecause the scientific and engineering numeric floating-point calculation approximates real arithmetic, the precision of this format can create situations wherein your floating-point operations results are not acceptable in some domains.
orting C code to C++ is no big deal: change the source file’s extension from .c to .cpp and recompile. By contrast, porting C++ source code and binaries to C
