The != is a relational operator in C++ STL which compares the equality and inequality between unordered_set containers. The Comparison is done in the following procedure:
- First, the sizes are compared.
- Then, each element in one of the containers is looked for in the other.
unordered_set1 != unordered_set2
Parameters: This method takes the two unordered_set containers unordered_set1 and unordered_set2 as the parameters which are to be checked for equality.
Return Value: This method returns
- true: if both the unordered_set containers on the left and right of the operator are equal.
- false: if the unordered_set containers on the left and right of the operator are not equal.
Below examples illustrate the != operator:
a and b are equal a and c are not equal
- Why overriding both the global new operator and the class-specific operator is not ambiguous?
