set::upper_bound() function is a predefined function, it is used to get the upper bound of any element in a set.
set :: upper_bound()函数是预定义的函数,用于获取集合中任何元素的上限。
it finds upper bound of any desired element from the set. Upper bound of any_element means the first number in the set that's immediate next to any_element.
它从集合中找到任何所需元素的上限。 上界any_element手段的第一个号码的组的直接旁边any_element。
Prototype:
原型:
setst; //declaration set st::iterator it; //iterator declaration it=st.upper_bound(T key);
Parameter: T key; //T is the data type
参数: T键; // T是数据类型
Return type: If upper_bound of the key exists in the set iterator pointer to the upper bound, Else, st.end()
返回类型:如果键的upper_bound存在于指向顶部上限的设置迭代器指针中,否则为st.end()
Usage:
用法:
The function finds upper bound of any desired element from the set. Upper bound of x is immediate next of x.
该函数从集合中找到任何所需元素的上限。 x的上限紧邻x。
Example:
例:
For a set of integer, set st; st.insert(6); st.insert(4); st.insert(10); set content: //sorted always(ordered) 4 6 10 it=st.upper_bound(4) Print *it; //6
