Read chapter 4 in the book.
For the exercises below, write each task and then show the task with the output answer below it (I just want your work to be well-labeled and clear).
- Write a long sentence and store it into a new string object.
- Output the number of characters in the string.
- Demonstrate that you can locate the position of a substring inside the string.
- Output characters in the string from position 4 to position 9
- Create an HTML form with a text entry box. Print a long string (a paragraph) to the screen. Ask the user to enter a word or a phrase that is contained in the paragraph. Can you take the user input and report back a message like: "The search phrase you entered was found at position X in the string".
- Working with the form input from task 5 above, can you report back the total number of occurances of the user's phrase? You might look at the split() & loop code on page 80 - that's a good direction. Or you could try creating a regular expression based on user input. On this one, you should probably spend most of your time reading, then you'll be able to figure it out & code it pretty quick. Feel free to turn it in as far as you get it.
- Starting with the value of Pi, demonstrate the output of the Math object methods: sin, cos, tan, ceil, floor & round. You don't need to take any user input.
- Starting with a comma separated string like "dog,cat,horse,pig,llama" - split that string into and array and write a loop that outputs each array item on a separate line.
