Agile development has been around for only about 20 years. While this seems like a lot of time, but given that we use either no method, or old fashioned methods for 60+ years, and some places still use (or don’t use) them, it makes Agile still relatively new and a lot of people afraid of…
An insertion sort is a bit of a special case. It assumes that you will be given a set of values over time, and as you get them, you will insert the value into its correct location based upon the given values. Depending upon the data, and size, you could utilize different types of sort,…
While similar in name to the Merge Sort, the Merge Sorted is a bit of a special case type of sort, and shares none of the same methodology. In it, you take two, or more sources, which are already sorted, and you merge them together. As you merge them together, you determine from which list,…
Like the Quick Sort, the Merge Sort uses a divide and conquer method to help sort the data. In a given array, you start to subdivide your array into smaller arrays, sorting the data as you go along, only to merge it back together when you are done. The way you sort the data is…
The cin and cout commands are for reading and writing to the stream for the console. However, there are other streams, and we can set one up for reading from a file. Writing to a Text File To write to a file, you will need to create a variable used to access the file stream….
Setting the precision of numeric data is a little more complicated in C++ than in some other languages.First you, will need to include iomanip as a library to use some of these modifiers. A common method is to pass in stream manipulators to the stream to get numbers for format correctly. Some of the modifiers…
Where the char represents a single character, a string represents a collection of them acting as a single entity. On the “old days” a string was an array of characters, however, now a days, we have our own data type for them. A string is not a primitive data type, but an included class that…
The char data type is used to store a single character. The literal value is stored within a set single quotes. Old style C strings were actually an array of chars, but now we have our own string data type. Even when we store a number in a char, it is the char value, not…
