software development life cycle (SDLC)? The design and development of correct, efficient and maintainable programs depend on the approach adopted by the program to perform various activities that need to be performed during the development process. The entire program or software development process is divided into a no. of phases. The output of one phase provides the input for its subsequent phase.

Explain about the structured programming languages? STRUCTURED (MODULAR) PROGRAMMING: · It is a subset of procedural programming that enforces a logical structure on the program to make it more efficient and easier to understand and modify. · It was suggested by two mathematicians “Corrado Bohm” & “Guiseppe Jacopini” .It is also referred to as modular programming. · It employs a top-down approach which allows the code to be loaded into memory more efficiently and also be reused in other programs. · Modules are coded separately and once a module is written and tested individually, it is then integrated with other modules to form the overall program structure. · Modularization makes it easier to write, debug, and understand the program. · ...
Different Generations of Programming languages FIRST GENERATION: MACHINE LANGUAGE This concept is precisely connected to the advances in technology that brought about different generations of the computer. I Generation languages (1950 –Machine Level Language / Low level language / Binary Language):- In this language all the instructions are understood by the system. These programs are executed very quickly and efficiently. Since it is directly executed by the CPU. These languages are machine languages. To write programs in these languages the system technology must be required. The data is Non-portable. That means a program written in a system does not work in another systems. Advantage: The main advantage of machine language is that the code can run very fast and efficiently, since it is directly executed by the CPU. Disadvantage: · However, this language is difficu...
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 ...

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...
