CPLString myString = "Hello World"; int size = myString.size(); // size = 11
CPLString first = "Hello"; CPLString second= " World"; CPLString result = first + second; // result = "Hello World"This code example creates two CPLString objects "first" and "second" and assigns them the values "Hello" and " World" respectively. The + operator is then used to concatenate the two strings and assign the result to a new CPLString object "result". The CPL library is a package library that provides a set of low-level utility functions that are platform independent. It is commonly used in geospatial data processing and analysis applications.
