Language Generation

  What is a computer?            Computer is an advanced electronic device that takes raw data as an input from the user and processes it under the control of a set of instructions (called program), produces a result (output), and saves it for future use. This tutorial explains the foundational concepts of computer hardware, software, operating systems, peripherals, etc. along with how to get the most value and impact from computer technology. Functionalities of a Computer  There are three basic functionalities of a Computer System and they are  1. Input  2. Process  3. Output  But if we look at it in a very broad sense, any digital computer carries out the following five functions: Step 1 - Takes data as input.  Step 2 - Stores the data/instructions in its memory and uses them as required. Step 3 - Processes the data and converts it into useful information.  Step 4 - Generates the output.  Step 5 - Controls...

  Flow Charts     Flow charts are a useful tool in many situations, as we make a process easy to understand at a glance. Using just a few words and some simple symbols, they show clearly what happens at each stage and how this affects other decisions and actions.   What Is a Flow Chart?     In 1921, the Frank and Lillian presented what was only a "graphic-based method" in a presentation titled: “ Process Charts: First Steps in Finding the One Best Way to do Work ”, to members of the American Society of Mechanical Engineers (ASME). When to Use a Flowchart?     Flowchart is a very simple yet powerful tool to improve productivity in both our personal and work life. Here are some ways flowchart can be helpful:   ·      Document a process ·      Present solution to a problem ·      Brainstorm ideas in a meeting ·      Design an operation system ·    ...

Array in c Programmimg  An array is a data structure in C programming that stores a fixed-size collection of elements of the same data type. In C, arrays are defined by their size and their data type. For example, an array of 10 integers would be defined as "int myArray[10];" and an array of 5 characters would be defined as "char myArray[5];". One of the main advantages of using arrays in C programming is that they allow for efficient access and manipulation of large amounts of data. For example, if you wanted to perform a specific operation on each element of an array, you could use a for loop to iterate through the array, rather than writing out the operation for each individual element. Arrays in C can be defined with a fixed size, called a static array, or with a size that can change at runtime, called a dynamic array. Static arrays have a fixed size, determined at the time of creation and cannot be modified afterwards. Dynamic arrays allow for the size to be mo...
