Q. Explain about the programming languages?

 

Programming language is a language specifically designed to express calculations that can be performed using computer.

 

Programming languages are used to create programs that control the behaviour of a system, to express algorithms or as a mode of human communication.

 

Programming languages have a vocabulary of syntax and semantics for instructing a computer to perform specific task.

 

Programming languages refers to high level languages such as BASIC, C,C++, PASCAL, etc. Each of these languages has a unique set of keywords and a special syntax for organizing programme instructions.

 

The programs that are written in any programming language has to be converted into the machine langue. There are two types to do this compiler and interpreting the program.

Q. Explain Advantages of Flowcharts

·      A flowchart is a diagrammatic representation that illustrates the sequence of steps that must be performed to solve a problem.

 

·      They are usually drawn in the early stages of formulating computer solutions to facilitate communication between programmers and business people.

 

·      Flowcharts help programmers to understand the logic of complicated and lengthy problems.

·      They help to analyze the problem in a more effective manner

 

·      Flowchart is also used for program documentation. Flowchart can be used to debug programs that have error(s).

 

Limitations of using Flowcharts

·      Drawing flowcharts is a laborious and a time consuming activity.

 

·      Flowchart of a complex program becomes, complex and clumsy. At times, a little bit of alteration in the solution may require complete re-drawing of the flowchart

 

·      Essentials of what is done may get lost in the technical details of how it is done.

 

·      There are no well-defined standards that limits the details that must be incorporated in a flowchart

  C LANGUAGE NOTES: Q. WHAT IS Algorithm explain its features? Ans :     A sequential solution of any program that written in human language, called algorithm. “Algorithm" is a formally defined a step by step procedure for performing some    calculation. If a procedure is formally defined, then it must be implemented using a programming language .             The algorithm gives logic of the program, that is, a step-by-step description of how to arrive at a solution. Algorithm provides a blueprint to write a program to solve a particular problem in finite number of steps. Algorithms are mainly used to achieve software re-use it is a procedure for performing some calculations. it gives the logic of the program i.e. a step by step description of how to arrive at a solution. Algorithm provides a blue print for writing a program to solve a particular problem. a well defined a...

 OOPs BASICS:                       Object Oriented Programming (OOP) is an approach to program organization and development, which attempts to eliminate some of the pitfalls of conventional programming methods by incorporating the best of structured programming features with several new concepts. However not all languages are suitable to implement the OOP concept easily. Languages that support OOP features include Smalltalk, C++, Ada and object pascal.  Object Oriented Paradigm:           The major Objective of Object Oriented approach is to eliminate some of the flaws encountered in the procedural approach. OOP treats data as a critical element in the program development and does not allow it to flow freely around the system. It ties data more closely to the functions that operate on it and protects it from unintentional modification. OOP allows us to decompose a pro...

JAVA NOTES

 HISTORY Java's history  began in 1991 at Sun Microsystems with James Gosling and his team, initially working on the "Green Project" .   The language was later named Oak, then Java, and publicly introduced in 1995 as a platform-independent language.  Sun Microsystems later became Oracle, and Java's stewardship has continued with Oracle.   1991: The "Green Project" begins at Sun Microsystems, led by James Gosling. 1992: The prototype, "Oak," is developed. 1994: The team refocuses on web-based applications. 1995: Java is publicly released by Sun Microsystems, emphasizing "Write Once, Run Anywhere" portability. 2006: Sun Microsystems makes Java's core components open-source. 2009: Oracle acquires Sun Microsystems, becoming Java's steward. 2014: Java 8 is released, modernizing the language with new features. 2017: Oracle adopts a six-month release cycle, accelerating updates
