Program 1

• Take a sentence as input from user
• Calculate and show: sentence's length, number of vowels.

Program 2

• Take a number n between 5-20 as input from user
• Create an array of length n
• Put random number (1-100) in each element of the array
• Display the array's element by comma separated. Eg. 1,56,2,88,2
• Show the sum of the all the elements of the array

Program 3

• Take a number n between 5-20 as input from user
• Create an array of length n
• Put random number (-100 to 100) in each element of the array
• Find the largest number in the array
• Add that largest number to all the array elements

Program 4 - Mini 2d game

• Make a game grid of 10x10 length.
• Each tile of the grid should show as a .
• Example, a 3x3 grid would show as:

...
...
...

• Place the game character at (0,0) and it show as x. Eg:

x..
...
...

• Now continously take input from user. If user pressed up arrow, move the x character up, if user presses left, move left and so on...
• On each arrow press, clear the screen and reprint the game grid with current state.

Program 5 - Fixed length Stack

• Make an array of integers. Length should be 10. This array's length is always 10.
• Fill the array with random integers from 0-100.
• Print the array on the screen like so: 3 | 4 | 8 | 54 | 99
• Now continuously take input from user.
• If user presses a number, insert the number to the right. And because the array length should always be 10, remove one number from the left.
• After any input, clear the screen and reprint the array.

Program 6 - Fixed length Stack (Level 2)

• This is to be done on top above program "Fixed Length Stack".
• If during input loop, user presses right arrow, set the insert direction to "right". That means any subsequent numbers should be inserted from right.
• If during input loop, user presses left arrow, set the insert direction to "left". That means any subsequent numbers should be inserted from left.
