Algorithm, is a work plan that shows the sections of a duty.

1. What is Algorithm ? Algorithm, is a work plan that shows the sections of a duty.

2. Example • Join Hacettepe Robotics Community. • Study hard. • Join Robot Projects. • Graduate from Hacettepe. • Find a Job with high salary. • Enjoy ! ☻

3. How to make an Algorithm ? • Flowcharts • Pseudocodes

4. Flowcharts

5. Yes Start Tap Temperature No Temp. <25 ? Print ‘hot’. Print ‘Cold’. End

6. Types of Flowcharts • Sequence • Selection • Loop

7. Start Start Start Sequence Selection Loop Decision Process Process Process Process Process Decision Process End End End

8. Pseudocodes • Have a usage like routine speaking. • No syntax. • Aims to understand how program works.

9. Example • 1 if • 2 students grade > 60 • 3 print ‘PASSED’ • 4 else • 5 print ‘FAILED’

10. Introduction to C Programming • Standart libraries • Standart input/output functions • Data types • Variable declarations • Operators

11. Standart Libraries • Stdio.h ( Standart input/output) : • Defines variable types • Various functions for performing input / output • Stdlib.h ( Standart Library) : • Various functions for performing general functions

12. Standart Libraries • Define Library; • #include<stdio.h> • #include<stdlib.h>

13. Standart Input / Output Functions • Printf • Scanf

14. Printf 1)Single Text; • printf("Hello World !");

15. Printf 2)Control Characters;

16. Printf 3)Conversion Specifier(Place Holder);

17. #include <stdio.h> int main() { printf("Welcome to Hacettepe Robotics Community!\n"); }

18. Scanf • scanf("%Conversion_specifier",&Variable _name);

19. #include <stdio.h> int main() { int x,y,sum; printf("Insert x and y>> !\n"); scanf("%d%d",&x,&y); sum=x+y; printf("Sum is >> %d",sum); }

21. For a single character Data Type For a string Conversion Specifier

22. Aritmetic Operators

23. Assignment Operators

24. Compare Operators
