Understanding HBufC

We can use HBufC when we don't know the size of data that we want to have in the descriptor. Letter 'C' in HBufC stands for constant that means the data is constant but it can also be changed in two ways . First using the assignment operator and another by using the Modifiable pointer descriptor.
