  CASE 1:  Given two numbers a & b, swap these two numbers using the friend function of C++.  Examples:   Input : a = 5, b = 9 Output : a = 9, b = 5 Input : a = 4, b = 6 Output : a= 6, b = 4 Approach:  Create a class Swap, declare one variable in it, i.e., num, and create a constructor for inputs. Declare a friend function in it. Define the friend function outside the class scope by taking arguments as call by reference to pass the copy of Swap Object. Perform the swap operation.

  What is static member functions? A static member function can access static data members and static member functions inside or outside of the class. Static member functions have a scope inside the class and cannot access the current object pointer. You can also use a static member function to determine how many objects of the class have been created. Static Member Function in a class is the function that is declared as static because of which function attains certain properties as defined below: A static member function is independent of any object of the class.  A static member function can be called even if no objects of the class exist. A static member function can also be accessed using the class name through the scope resolution operator. A static member function can access static data members and static member functions inside or outside of the class. Static member functions have a scope inside the class and cannot access the current object pointer. You can also u...

 A data member of a class can be qualified as statics. The properties of a static member variable are similar to that of a C static variable. A static member variable has certain special characteristics. These are: It is initialized to zero when the first object of its class is created. No other initialization is permitted. Only one copy of that member is created for the entire class and is shared by all the objectives of that class, no matter how many objects are created. It is visible only within the class, but its lifetime is the entire program. #include <iostream> using namespace std; class item {        static int count;        int number;        public:        void getdata(int a)        {            number=a;            count ++;        }        void getcount(void)   ...

An array can be of any data type including struct. Similarly, we can also have arrays of variables of the type class. Such variables are called arrays of objects. Class Definition: class employee {           char name[30];          float age;     public:          void getdata(void);           void putdata(void); }; The identifier employee is a user-defined data type and can be used to create objects related to different employee categories. employee manage[3];          //aray of managers employee foreman[15];       //array of foreman employee worker[75];        // array of worker the array manager contains three objects(managers), namely, manager[0],  manager[1], and manager[2], of type employee class similarly, the foreman array contains 15 objects. and the worker array contains 75 objectives.(work...

In order to understand the nature of data it is necessary to categorize them into various types.  Different categorizations of data are possible.  The first such categorization may be on the basis of disciplines, e.g., Sciences, Social Sciences, etc. in which they are generated.  Within each of these fields, there may be several ways in which data can be categorized into types. There are four types of data:  Nominal  Ordinal  Interval  Ratio  Each offers a unique set of characteristics, which impacts the type of analysis that can be performed. The distinction between the four types of scales center on three different characteristics: The order of responses – whether it matters or not The distance between observations – whether it matters or is interpretable The presence or inclusion of a true zero Nominal Scales Nominal scales measure categories and have the following characteristics: Order: The order of the responses or observations does not mat...

Today, it is an era of a tight handshake between business, IT, and yet another class called Data Scientists. Here, we are citing there vital reasons why companies should compulsorily consider leveraging big data. Competitive advantage: The most important resource with any organization today is their data. What they do with it will determine their fate in the market. Decision Making: It has shifted from the hands of the elite few to the empowered many. Good decisions play a significant role in furthering customer engagement, reducing operating margins in retail, cutting and other expenditures in the health sector. Value of data: The value of data continues to see a steep rise. As an all-important resource, it is time to look at newer architecture, tools, and practices to leverage this.

 Binning Method Binning is a technique for smoothing data or dealing with noisy data. The data is sorted first, and then the sorted values are dispersed into a number of buckets or bins in this approach. Binning methods provide local smoothing since they consult the vicinity of values.  Smoothing can be accomplished in three ways: Bin smoothing entails:  Each value in a bin is replaced by the bin's mean value when smoothing by bin means is used.  Smoothing by bin median:  Each bin value is replaced by its bin median value in this method.  Smoothing by bin borders:  In smoothing by bin boundaries, the bin boundaries are determined as the minimum and maximum values in a given bin. The nearest boundary value is then used to replace each bin value. Example: Sorted data for price (in dollars): 4, 8, 9, 15, 21, 21, 24, 25, 26, 28, 29, 34 Smoothing by bin means:       - Bin 1: 9, 9, 9, 9       - Bin 2: 23, 23, 23, 23   ...

  Installing Hadoop 3.2.1 on Windows 1.Prerequisites First, we need to make sure that the following prerequisites are installed: Java 8 runtime environment (JRE): Hadoop 3 requires a Java 8 installation. I prefer using the offline installer. Java 8 development Kit (JDK) To unzip downloaded Hadoop binaries, we should install 7zip   I will create a folder on my local machine to store downloaded Hadoop files "Drive_Name:\Hadoop_evn" 2. Download Hadoop Barriers The first step is to download Hadoop binaries from the official website . The binary package size is about 342 MB. or  Better to download Hadoop Binaries from the nonofficial . you can directly utilize these file.  After finishing the file download, we should unpack the package using 7zip int two steps. First, we should extract the hadoop-3.2.1.tar.gz library, and then, we should unpack the extracted tar file 3. Setting up environmental Variables After installing Hadoop and its prerequisites, we should configure...
