The document discusses programming fundamentals and decision making in programs. It provides examples of programs that calculate simple tasks like area of a rectangle and difference between two numbers. It then explains how decision boxes allow programs to make decisions based on conditions, like checking if a difference is positive or negative. Decision making allows programs to solve more complex problems by performing comparisons and branching execution. Keywords like "if", "whether" indicate when decision making is required to solve a problem.

1. Programming Fundamentals

5. Difference of Two numbers Programming Fundamentals | Lecture-3 START READ number1, number2 difference = number1 - number2 DISPLAY difference STOP Will result in a negative value if number1 is smaller than number2

6. Is This Solution Correct? Programming Fundamentals | Lecture-3 START READ number1, number2 difference = number1 - number2 DISPLAY difference STOP difference = difference * -1

9. Should we design two different solutions? Programming Fundamentals | Lecture-1

11. Decision Box Programming Fundamentals | Lecture-3 Decision Rule Yes No Always in the form whose answer is “ Yes” or “No”

12. Programming Fundamentals | Lecture-3 START READ number1, number2 difference = number1 - number2 DISPLAY difference STOP difference = difference * -1 difference < 0 Yes No

15. Programming Fundamentals | Lecture-3 START READ number1, number2 DISPLAY smaller STOP smaller = number1 number1 < number2 Yes No smaller = number2

16. Alternative Programming Fundamentals | Lecture-3 START READ number1, number2 STOP DISPLAY number1 number1 < number2 Yes No DISPLAY number2

18. Output a Message Programming Fundamentals | Lecture-3 DISPLAY “This is a message”

22. Programming Fundamentals | Lecture-2 BE PREPARED FOR QUIZ IN NEXT LECTURE
