struct divides;

Description

divides is a binary function object. Its operator() returns the result of dividing x by y. You can pass a divides object

to any algorithm that requires a binary function. For example, the transform algorithm applies a binary operation

to corresponding values in two collections and stores the result. divides would be used in that algorithm in the

following manner:

vector<int> vec1;

vector<int> vec2;

vector<int> vecResult;

transform(vec1.begin(), vec1.end(), vec2.begin(), vecResult.begin(),

divides<int>());

After this call to transform, vecResult[n] will contain vec1[n] divided by vec2[n].
