} There is an array containg 11 elements. What are possible indexes I can use? (what value can I put in place of question mark: array[?])
Declare an array of any type (e.g. int).
Declare one dimensional array of int type which contains 10 elements.
Then print an information confirming the length of the array.
Declare one dimensional array of int type which contains 10 elements.
Then fill in the array with random values 0 or 1.
Write a program that counts how many 0's and 1's are in the array from the previous task.
Create 2D array and display it as a table. Value of each element should be a sum of row and column index.
There is a 20 elements array. Find the index of the lowest value.
Create a character array (char as type) and put there your nickname / name.
Then display whole message (character by character).
Display your nickname / name, but in reversed way.
Check if a text written as char array is a palindrome.
Create an array that contains bits representation of an integer.
i.e. 2353 -> [0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,0,0,1,0,0,1,1,0,0,0,1]
Disclaimer: it is not about printing, but creating a new array
Create a 2D array, that each row has a different length.
Display all elements.
Display sum and average of all elements of an integer array.
Values of array should be generated randomly in range set by user.
Create a program, that sorts an integer array.
Create Tic Tac Toe.
