point cloud library PCL Ptr pcl::PointCloud<pcl::PointXYZ>::Ptr cloud (new pcl::PointCloud<pcl::PointXYZ>)

pcl::PointCloud<pcl::PointXYZ>::Ptr cloud (new pcl::PointCloud<pcl::PointXYZ>)

What is this variable Ptr here ? I tried to find it out but could not get any relevant information.

Relevant information is online if you go looking for it.

The PCL documentation will tell you what Ptr is.

typedef boost::shared_ptr< PointCloud<PointT> >   Ptr

i.e. Ptr is a typedef to a smart pointer of the Boost library.

Then, any C++ documentation will tell you what a typedef is, and Boost documentation will tell you what a smart pointer is.

(cloud is the variable here, not Ptr. Ptr is part of the type.)

The PCL basic tutorials is what you need to go through.
