第二个字符常量表达式包含了单一字符“\100”,如果字符 64 不在基本运算字符集中,这也将是由实现定义的。 code[5] = ‘\109’ ;/* implementation-defined, two character constant */code[6] = ‘\100’ ;/* set to 64, or implementation-defined */ 最好根本不要使用八进制常量或 escape 序列,并且要...

you will need to build within a case-sensitive file system. The simplest approach is to create and mount a new disk image with a case sensitive format. Make sure that the mount point does not contain spaces. This
According to Simpson’s rule, the number of intervals will impact on the precision. You are required to try different numbers of intervals and see how it impacts your result. Please present an analysis about this in your report. \section{Code of Solution} The followings are codes implemented ...
}Template Default Arguments and Class Templates当一个 class template 的所有模板参数都带默认值时，我们定义类时，需要带一个 <> ，例如template <class T = int> class Numbers {public:Numbers(T v = 0) : val(v) {}private:T val;}Numbers<long double> lots_precision;Numbers<> average_precision;...

Any of these formats may have been prefixed by a sign and may have been formatted slightly differently depending on field width and precision (sometimes with unusual effects, for example printf("%.2f\n", INFINITY) would print 1.#J because the #INF would be "rounded" to a 2-digit precis...
