# [Tutorial] 15 exercícios para aprender uma nova linguagem

## Recommended Posts

1. Display series of numbers (1,2,3,4, 5....etc) in an infinite loop. The program should quit if someone hits a specific key (Say ESCAPE key).

2. Fibonacci series, swapping two variables, finding maximum/minimum among a list of numbers.

3. Accepting series of numbers, strings from keyboard and sorting them ascending, descending order.

4. Reynolds number is calculated using formula (D*v*rho)/mu Where D = Diameter, V= velocity, rho = density mu = viscosity

Write a program that will accept all values in appropriate units (Don't worry about unit conversion)

If number is < 2100, display Laminar flow,

If it’s between 2100 and 4000 display 'Transient flow' and

if more than '4000', display 'Turbulent Flow' (If, else, then...)

5. Modify the above program such that it will ask for 'Do you want to calculate again (y/n),

if you say 'y', it'll again ask the parameters. If 'n', it'll exit. (Do while loop)

While running the program give value mu = 0. See what happens. Does it give 'DIVIDE BY ZERO' error?

Does it give 'Segmentation fault..core dump?'. How to handle this situation. Is there something built

in the language itself? (Exception Handling)

6. Scientific calculator supporting addition, subtraction, multiplication, division, square-root, square, cube,

sin, cos, tan, Factorial, inverse, modulus

7. Printing output in different formats (say rounding up to 5 decimal places, truncating after 4 decimal places,

padding zeros to the right and left, right and left justification)(Input output operations)

8. Open a text file and convert it into HTML file. (File operations/Strings)

9. Time and Date : Get system time and convert it in different formats 'DD-MON-YYYY', 'mm-dd-yyyy', 'dd/mm/yy' etc.

10. Create files with date and time stamp appended to the name

11. Input is HTML table, Remove all tags and put data in a comma/tab separated file.

12. Extract uppercase words from a file, extract unique words

13. Implement word wrapping feature (Observe how word wrap works in windows 'notepad')

14. Adding/removing items in the beginning, middle and end of the array.

Penso que ele queira dizer para explorares aqueles conceitos se forem suportados pela linguagem em questão.

Desculpem tar a renascer o topico, mas era so para expressar a minha opinião, eu fazia apenas uma coisa simples: uma calculadora com as quatro operações aritmeticas...

E claro, para agradecer, bom conjunto de exercicios  🙂
