- 3. We learn before We Define Computer & Program Define Computer Programming Programming Process Programming Language Inputs & Outputs Define Logical Processing Variables Data Types Programming Fundamentals TRIVUz Academy www.trivuzacademy.com
- 4. We will learn today Conditional Statement If… then … else Switch statement Operators Programming Fundamentals TRIVUz Academy www.trivuzacademy.com

- 14. If…else statement execute some code if statement is true and some other code if statement is false TRIVUz Academy
- 15. If…else… if (conditional) { // statement if true } TRIVUz Academy

- 29. switch switch (value) { case 1: // some code to execute break; TRIVUz Academy
- 30. switch switch (value) { case 1: // some code to execute break; case 2: // some code to execute break; TRIVUz Academy
- 31. switch switch (value) { case 1: // some code to execute break; case 2: // some code to execute break; default: // nothing matches, do it TRIVUz Academy
- 32. switch switch (value) { case 1: // some code to execute break; case 2: // some code to execute break; default: similar to else in if..else // nothing matches, do it TRIVUz Academy
- 33. switch switch (value) { case 1: // some code to execute break; case 2: // some code to execute break; default: // nothing matches, do it } TRIVUz Academy
- 34. switch switch (n) { case label1: code to be executed if n=label1; break; case label2: code to be executed if n=label2; break; default: code to be executed if n is different from both label1 and label2; } TRIVUz Academy
