The secret to this is Scratch. Created by the Lifelong Kindergarten group at the Massachusetts Institute of Technology Media Lab in 2006 as an offshoot of the Squeak and Smalltalk languages, Scratch takes the core concepts of programming and makes them accessible to all. Unlike a traditional ...
2. We can build programs from the standard working modules that communicate with one another, rather than having to start writing the code from scratch. This leads to saving of development time and higher productivity. 3. This principle of data hiding helps the programmer to build secure program...
