  1. Standard Input - Output By: Muhammad Zidny Naf’an Algorithm and Data Structure, UIN Syarif Hidayatullah Jakarta, 2012

  2. Output Command • cout() • printf() • puts() • putchar() Algorithm and Data Structure, UIN Syarif Hidayatullah Jakarta, 2012

  3. cout() • Show the data to screen • We must include header file “iostream.h” • Ex: Algorithm and Data Structure, UIN Syarif Hidayatullah Jakarta, 2012

  4. printf() • Function declaration: printf(“string control”, argument1, argument2); • Use header header “stdio.h” Algorithm and Data Structure, UIN Syarif Hidayatullah Jakarta, 2012

  5. printf() • Ex: Algorithm and Data Structure, UIN Syarif Hidayatullah Jakarta, 2012

  6. puts() • Print the string in the screen • Use “stdio.h” Algorithm and Data Structure, UIN Syarif Hidayatullah Jakarta, 2012

  7. putchar() • Print a character to screen Algorithm and Data Structure, UIN Syarif Hidayatullah Jakarta, 2012

  8. Manipulation Algorithm and Data Structure, UIN Syarif Hidayatullah Jakarta, 2012

  9. endl() • Insert new line Algorithm and Data Structure, UIN Syarif Hidayatullah Jakarta, 2012

  10. ends() • Insert null character Algorithm and Data Structure, UIN Syarif Hidayatullah Jakarta, 2012

  11. dec, oct, hex • Convert number to decimal, octal, and hexadecimal • Use “iomanip.h” Algorithm and Data Structure, UIN Syarif Hidayatullah Jakarta, 2012

  12. setprecission() • Formatting the number of decimal digit that will showed • Use “iomanip.h” Algorithm and Data Structure, UIN Syarif Hidayatullah Jakarta, 2012

  13. setbase(base number) • To convert decimal, hexadesimal, and octal. • Base number: 10 for decimal, 8 for octal, 16 for hexdecimal Algorithm and Data Structure, UIN Syarif Hidayatullah Jakarta, 2012

  14. setw(int width) • Set variable’s width in screen • User “iomanip.h” Algorithm and Data Structure, UIN Syarif Hidayatullah Jakarta, 2012

  15. setfill(char character) • Fill blank from setw with character • Use iomanip.h Algorithm and Data Structure, UIN Syarif Hidayatullah Jakarta, 2012

  16. setiosflags() • Formatting output • Example: Align text in screen (align left or right) • Using “iomanip.h” Algorithm and Data Structure, UIN Syarif Hidayatullah Jakarta, 2012

  17. Algorithm and Data Structure, UIN Syarif Hidayatullah Jakarta, 2012

  18. Input Command • cin • scanf() • gets() • getch() • getche() Algorithm and Data Structure, UIN Syarif Hidayatullah Jakarta, 2012

  19. cin • Without formatting input • Use “iostream.h” Algorithm and Data Structure, UIN Syarif Hidayatullah Jakarta, 2012

  20. scanf(“format setting”, &variable) • Input data with formatting Algorithm and Data Structure, UIN Syarif Hidayatullah Jakarta, 2012

  21. scanf(“format setting”, variable) • Example: • Use “stdio.h” Algorithm and Data Structure, UIN Syarif Hidayatullah Jakarta, 2012

  22. gets(char[] string) • Input string from keyboard • Use “stdio.h” Algorithm and Data Structure, UIN Syarif Hidayatullah Jakarta, 2012

  23. getch() • Stands for get character and echo • Input one character, and we aren’t need push “enter” button to execute, and character will not be showed in screen • Use “conio.h” Algorithm and Data Structure, UIN Syarif Hidayatullah Jakarta, 2012

  24. getch() • Stands for get character and echo • Input one character, and we aren’t need push “enter” button to execute, and character will be showed in screen • Use “conio.h” Algorithm and Data Structure, UIN Syarif Hidayatullah Jakarta, 2012

  25. Exercise • Write the program to count average from a student’s score. The are 3 scores. • Average Formula = (score1+score2+ score3)/3 • Input format: • Output format: ********** INPUT SCORE ********* Name : <input> score 1 : <input> score 2 : <input> score 3 : <input> ********** AVERAGE SCORE ********* Name : <name> score 1 : <score1> score 2 : <score2> score 3 : <score3> Average: <average> Algorithm and Data Structure, UIN Syarif Hidayatullah Jakarta, 2012
