// EXERCISE: Assign the Arrays
|
|
//
|
|
// 1. Create an array named books
|
|
// 2. Add book titles to the array
|
|
// 3. Create two more copies of the array named: upper and lower
|
|
// 4. Change the book titles to uppercase in the upper array only
|
|
// 5. Change the book titles to lowercase in the lower array only
|
|
// 6. Print all the arrays
|
|
//
|
|
// NOTE
|
|
// Check out the strings package, it has function to convert cases to
|
|
// upper and lower cases.
|
|
//
|
|
// BONUS
|
|
// 1. Invent your own arrays with different types other than string,
|
|
// and do some manipulations on them.
|
|
//
|
|
// 👉 THISSSS--------------------------------------------------------
|
|
// 2. Find some Turkish book titles and do the same upper, lowercase conversion
|
|
// for them.
|
|
//
|
|
// Here are some books: https://www.goodreads.com/group/bookshelf/417154-bilimkurgu-kul-b?shelf=read
|
|
//
|
|
// Note: You'd need to use special functions to convert the Turkish letters.
|
|
// They're in the strings package as well.
|
|
//
|
|
// EXPECTED OUTPUT
|
|
// ?
