Notes

Programming languages

The thorough understanding regarding the entire process of the development of programs is called Programming concept. It is a way of creating a sequence of instructions to enable the computer to do something. A programming language is the language used by computers by which they understand to do what the program users want. there are 2 types of programming languages; Low Level Language (LLL) and High Level Language (HLL).

Language Translators And High Level Programming Languages

Language translator is a program which is used to translate instructions that are written in source code to object code i.e. from high-level language or assembly language into machine language. Assembler is the language translator designed to translate assembly language program (source codes) into machine language program (object codes). A compiler is a language translator that translates high-level languages program to machine language program.

Concept of Program and Programming statement

A program is a set of instructions or statements to perform some specific tasks. An instruction (also called code) written in the high level language to do a specific task in a program is called Programming statement. Program errors are called bugs. The process of locating and correcting bugs after their detection is known as debugging.

Program Design tools

Program Design tools are the tools used to develop a program. A program is the expression of an algorithm in a programming language. An algorithm is a sequence of instructions or step by step instruction to find the solution of a problem. A flowchart is a pictorial representation of an algorithm. Program flowchart describes the sequence of operations and decisions for a particular program. A flowchart that gives information about a system is called System flowchart.

Introduction to Data type and Codes

Data type specifies the type of data that is to be used in a program. A data structure is an organized group of data items which is treated as a unit. Array Structure Array is a collection of sequences, of storage of same type of data such as integer, real or character. Structure is a collection of heterogeneous data (different types of data) under a same name. Array are one dimensional, two dimensional or three dimensional. Structure is only of one dimension. In array, we can store any number of data such as Integer, Real or Character.

Program control structure

The structures which regulate the order in which program statements are executed are called Control Structures. Sequence is the set of program instructions which follow one another and are to be executed unconditionally. Selection is the set of instructions which are to be executed conditionally. Iterations are the computer instructions which are to be performed repeatedly and conditionally.
