std::cout << std::setprecision(2) << std::fixed <<1.23456<<"\n"; which is a lot of typing compared to printf: printf("%.2f\n",1.23456); Matthew Wilson, the author of FastFormat, called this "chevron hell". iostreams don't support positional arguments by design. ...
You have already seen that avectoron its own is quite useful and versatile. It is the workhorse of the STL and the container of choice for most financial modeling applications (as well as for many other application domains). For this reason alone, it is worth getting familiar with thevector...
We’ve seen a bit of I/O in the C Standard Library already, but this isn’t C++’s main way to perform I/O. Today we’ll look at the “streams” API that’s designed around C++’s support for strong types and overloaded operators rather than facilities like “format strings.” We...
