Description

greater_equal is a binary function object. Its operator() returns true if x is greater than or equal to y. You

can pass a greater_equal object to any algorithm that requires a binary function. For example, the sort

algorithm can acceept a binary function as an alternate comparison object to sort a sequence. greater_equal

would be used in that algorithm in the following manner:

vector<int> vec1;
