C++ By Example: UnderC Learning Edition

Chapter 3. Arrays and Algorithms

So far we have discussed the core arithmetic and logical operations of C++, as well as features such as strings and input/output that are part of the standard library. In the case study in Chapter 2, “Functions and Control Statements,” we hit some limitations of basic C++. To pass a number of integers as a parameter, we were forced to write them as a string. There are two problems with this; first, there is no guarantee that these are all valid integers, and second, this would be very inefficient for really large lists of integers. That case study also depends heavily on having everything like ID lists in the correct order, but we cannot control the world, and often things happen in an order other than what we ...
