Array of Objects

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...

Binning Method by Data smoothing in python

 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   ...

Hadoop file Management Tasks

  Implement the following file management tasks in Hadoop: a) Adding files and directories b) Retrieving files c) Deleting files Hint: A typical Hadoop workflow creates data files (such as log files) elsewhere and copies them into HDFS using one of the above command line utilities. Program:  The most common file management tasks in Hadoop includes: Adding files and directories to HDFS Retrieving files from HDFS to local filesystem Deleting files from HDFS Hadoop file commands take the following form:     hadoop fs - cmd Where cmd is the specific file command and <args> is a variable number of arguments. The command cmd is usually named after the corresponding Unix equivalent. For example, the command for listing files is ls as in Unix. a) Adding Files and Directories to HDFS Creating Directory in HDFS    $ hadoop fs - mkdir foldername (syntax)  $ ha...
