1. Programming Fundamentals

2. This Course Problem Solving Using Computers Implementing the Solution using a Programming Language 1 2 The first part is mostly ignored which leads to poor programming skills Programming Fundamentals | Lecture-2

3. 1

4. Steps in Problem Solving Define the Problem Design the Solution 1 2 Programming Fundamentals | Lecture-2

6. 2. Design the Solution Solution of a Problem in your mind Solution in terms of no. of steps Transform There are more than 1 ways to do that but we will use a graphical approach which will involve usage of Geometrical Shapes to represent different kinds of steps in a solution Programming Fundamentals | Lecture-2

7. Example-1 Programming Fundamentals | Lecture-2

8. Step-1: Define the Problem Programming Fundamentals | Lecture-2 Problem : Find the sum of two numbers Input Output Processing Number1 Sum Add Numbers Together Number2

10. Step-2: Design the Solution Programming Fundamentals | Lecture-2 START READ number1, number2 sum = number1 + number2 DISPLAY sum STOP

11. Legend Programming Fundamentals | Lecture-2 Symbol Meaning Terminal Symbol (Oval) : indicates the beginning and ending of a program Input-Output Symbol (Parallelogram): shows an input or an output operation Process Symbol (Rectangle): shows an instruction other than input or output

13. Average of Two Numbers Programming Fundamentals | Lecture-2 START READ number1, number2 sum = number1 + number2 DISPLAY average STOP average = sum / 2

14. Square of a Number Programming Fundamentals | Lecture-2 START READ number square = number * number DISPLAY square STOP

15. Acceleration Programming Fundamentals | Lecture-2 START READ v1, v2, t change = v2 – v1 DISPLAY acceleration STOP acceleration = change / t

16. Velocity Programming Fundamentals | Lecture-2 START READ d1, d2, t1, t2 positionChange = d2 – d1 DISPLAY velocity STOP timeChange = t2 – t1 velocity = postionChange / timeChange
