sorted and shuffled vectors
| kohline (2) | |||
| hi i"m new to c++ and became a program to insert some stuff. there is a class called Cluster those clusters appear mostly as vector<Cluster> if i define
Cluster cluster;there is something like
cluster.size()which will give me the number of elements inside my cluster. i now want to sort the vector<Cluster> with respect to the number of elements in my cluster. afterwards i want to pick only the ones with less than 5 elements, and erase them from vector<Cluster>. afterwards i have to access the vector<Cluster> but i dont want the vector<Cluster> to be accessed from smallest to largest cluster. are there some ideas how to achieve this? thanks a lot kohline | |||

| You can overload the operators "<", ">", "==" for your class and use the sort() function from the algorithms... Using the "<" operator you can find which one has less than 5 elemnts and erase it.
Use random() to shuffle it... | |||
