 Computer Programming & Programming Methodology Unit-1 Introduction A computer cannot perform any task of its own and can only understand its own language which is the language of 0’s and 1’s that means binary number system, therefore a computer user has to communicate with a computer using the language which they can understand. The set of instructions to perform a task in the computer that is known as a program and the computer languages in which programs are written is known as programming language. The person developing or writing programs is known as “programmer” . A computer cannot understand the natural language like English. Examples of programming languages are C, C++, C#, Perl, Java, etc. Introduction to C Programming History of C Programming  C is a programming language which was developed at “AT & T’s Bell  Laboratory” of USA in 1972.  C was written by Dennis Ritchie, that‟s why he is also called as father of  C Programming language.  C was created ...

 1.1 FUNDAMENTALS OF WORKBOOK ~Concept of workbook A workbook is a file that contains one or more worksheets to help you organize data.  You can create a new workbook from a blank workbook or a template. A spreadsheet or worksheet is a file made of rows and columns that help sort data,  arrange data easily, and calculate numerical data. A spreadsheet software program has  ability to calculate values using mathematical formulas and the data in cells. A spreadsheet is a grid of boxes. Each box is called a cell. Each cell is located in a  particular row and column in the grid. Each cell is available to store data. The spreadsheet can contain 32000 rows and 255 columns. More than one cell is called a range of cells. You can select a range of cells and move  them, copy them, format them and so on as easily as a single cell. Spreadsheets are used to store a table or group of tables .A table is a range of cells with  related data. To store tables that are rel...

1.4 Block Diagram and functional units of  computer o Following are the components of computer: 1. Input Unit 2. Output Unit 3. Storage Unit 4. CPU 5. ALU 6. CU 1. Input Unit: ▪ It performs following functions:        a. Accepts instructions and data from                         outside world.        b. It converts instructions and data in                          computer acceptable form.        c. It supplies the converted instructions and             data to the computer system for further processing. ▪ Data and instructions enter in the computer in a form that depends upon input device being used. ▪ All input devices must transform input signals to binary codes which are done by input interface. ▪ Input interface watch unique physical and electrical char...
