Lab 10

1. Write a complete C++ program that asks the user to type a big integer n. It should then ask 4 times for the user to type a smaller value of n and then terminate the program. However, if the user enters a value that is not smaller it should immediately say "Goodbye" and terminate the program.
A sample run of the program:

Type a big integer n: 100 Type a smaller value of n: 20 Type a smaller value of n: 10 Type a smaller value of n: 2 Type a smaller value of n: 1

Another sample run of the program:

Type a big integer n: 100 Type a smaller value of n: 0 Type a smaller value of n: 0 Goodbye


2. Write a complete C++ program that does the following:
• Asks the user for an odd positive integer.
• Reads a value n entered by the user. If the value is not legal, force the user to enter a valid input.
• The program prints an n x n grid displaying a backwards Z shape with the following properties:
• A diagonal row of X's running from the top left corner to the bottom right corner.
• With the exception of the X from the diagonal, a row of O's in the top row and bottom row.
A sample run of the program:

Enter value for n: 5 XOOOO X X X OOOOX
3. Write a complete C++ program that does the following:
• It asks the user to enter an odd positive integer.
• The program reads a value n entered by the user. If the value is not legal, the program terminates.
• The program prints an n x n grid displaying a line running from the top left of the screen to the bottom right. The top left half of the line should be made with the character +, the bottom right half should be made with the character x and the very center should be a *.
A sample run of the program:

Enter value for n: 7 + + + * x x x


4. Write a complete C++ program that does the following:
• It asks the user to enter an odd positive integer.
• The program reads a value n entered by the user. If the value is not legal, the program terminates.
• The program prints an n x n grid displaying a large letter X. The left half of the X should be made with the character +, the right half should be made with the character x and the very center should be a *.
A sample run of the program:

Enter value for n: 7 + x + x + x * + x + x + x


5. Write a complete C++ program that does the following:
• The program asks the user to enter an integer between 1 and 20.
• If the user enters an illegal number, the program repeatedly asks the user to correct their number.
• If the user has not entered a correct number after 10 attemps, the program chooses 10 as the user's number.
• The program prints the cube of the user's number.
A sample run of the program:

Enter an integer between 1 and 20: 100 Out of range. Enter an integer between 1 and 20: -1 Out of range. Enter an integer between 1 and 20: 5 The cube of your number is 125.
