Within the methods used to create the objects, teh references to the getCapacity method both return the correctly calculated value. Stack memory is set up by a simple variable declaration as shown in the example: Allocated on the heap, the memory containing the object persists until the end of your program, or until you delete the object. Allocated on the stack, the variable persists until the end of the block in which it's defined. In C++, memory is allocated to variables on a stack or on a heap.

Lisa and I (Graham) now live in what was our training centre in Melksham - happy to meet with former delegates here - but do check ahead before coming round. Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own risk. We have made many, many friends over 25 years of teaching about Python, Tcl, Perl, PHP, Lua, Java, C and C++ - and MySQL, Linux and Solaris/SunOS too. For 2023 - we are now fully retired from IT training.
