"Understanding coding" app is for those, who knows the syntax of coding but dont know where and when to use that syntax. Sometimes we need more practice to understand the coding. In this app, almost all the important topics of the programming languages (C, C++, Python and Java) have covered by us. Few codes are there for every topic of programming language which will help a coder to build logic for coding.Topics in C (First appeared in 1972) :-Operators, If-else and Switch, Loops, Functions, Arrays & Strings, Pointers, Structures, Recursion and File HandlingTopics in C++ (First appeared in 1985) :- Operators, If-else and Switch, Loops, Functions, Arrays and Strings, Pointers, Structures, OOPs concepts, Recursion and File HandlingTopics in Python (First appeared in 1991) :- Operators, If-else, Loops, Functions, Lists and Strings, Tuples and Dictionaries, OOPs concepts, Recursion, Exception handling and File HandlingTopics in Java (First appeared in 1995) :- Operators, If-else and Switch, Loops, Methods, Arrays and Strings, OOPs concepts, Recursion, Exception handling, Multi-Threading and File HandlingIf you want to become a good coder in any of these languages, then you have to practice all topics of that language.In our app, there are many options on the single screen for example:-Practice questions for coding, Interview questions for interview, Symbols & more about syntax of programming etc.There are one more options which is the best part of our app that is D.F.P.R.T.D means Definitions of Important TopicsF means Facts about Programming P means Points to Remember in ProgrammingR means References to explore more about the LanguagesT means Tips which you will need at the time of ProgrammingIn our app, there is output for every code which will help you to understand, what is happening in the code. You can also change the background of code to read according to your vision and surroundings. (Need SD card to save files)You can save the code file any time from the app and you can also open that saved code files from the app in any editor in which you want to run code.There is also an option of practice questions in which we provide questions for practice of coding of almost every topic of programming language.There is an option of interview questions in which we provide questions for your interviews. There are around 100 Interview Questions which also help you to explore more about the programming language.You can also zoom-in and zoom-out the code and the output according to the code or output length in your phone or tablet.
