set::empty() functionis a predefined function, it is used to check whether a set is empty or not. If set is empty it returnstrue(1), if set is not empty it returnsfalse(0). Syntax set<T> st; //declaration set<T>::iterator it; //iterator declaration st.empty(); Parameter(s) ...
Theset::find() functionis a predefined function, it is used to check whether an element belong to the set or not, if element finds in the set container it returns an iterator pointing to that element. The function checks whether an element belong to the set or not. If an element belong...
The template function is an algorithm specialized on the container class multiset to execute the member functionleft.swap(right). This is an instance of the partial ordering of function templates by the compiler. When template functions are overloaded in such a way that the match of the template...

in the context of a project configuration, an item macro applies to all files of a certain type. For example, the C/C++Preprocessor Definitionsconfiguration property can take a%(PreprocessorDefinitions)item macro that applies to all .cpp files in the project. This kind of item macro corresponds...
Figure 1.1 math_FunctionSet class diagram in OPENCASCADE 2. Function Set 很多科学理论和工程技术问题都最终转化成非线性方程或方程组的求解,如对理论数据或实验观察的数据进行拟合用到的最小二乘法,就是一个典型的非线性方程组求解的问题。而在几何中的应用就更广泛了,像计算直线与平面的交点问题,点到自由曲线...
如果设置了 –f 标志,name 是指 function 的名称。取消设置 ERRNO、LINENO、MAILCHECK、OPTARG、OPTIND、RANDOM、SECONDS、TMOUT 和_ 将删除它们的特殊含义,即使随后指定了这些变量也是如此。使用unset 时,name 列表指定的变量将被取消分配,即这些变量的值和属性将被清除。readonly 变量无法取消设置。如果设置了 –f ...
