Complete the program simple_frogger.c, which is a simple version of the classic Frogger arcade game.

The game should start by printing a 9 x 9 map, to be built as follows:

• The Top Row alternates between house |^| and grass -.
• Next 3 rows are water ~, where logs -_- and alligators A can be added later.
• Next row is grass -.
• Next 3 rows is road =, where cars C can be added later.
• Bottom row is grass -.

The game then prompts the user to:

• Enter a column to place Frogger !F! on.
• Enter the row, column, and length of 3 logs in the water. These will be used to get Frogger across the river as it cannot jump onto the water.
• Enter the type, row, and column of 3 enemies which can be
  • Alligators (in the water)
  • Cars (on the road)

Once these elements have been added to the map, Frogger can start moving through the map using:

• u to move up
• d to move down
• l to move left
• r to move right

Frogger wins if it makes it to a house tile |^|.

Frogger loses if it goes into the water ~, or on an alligator A or car C.

Assumptions/Restrictions/Clarifications

• Error checking is not needed. You can assume only valid inputs will be given.
• Apart from Frogger, the map elements will not move during the game.

Although this cs_calculator.style.c program runs properly, the style is horrendous! Please help us fix up the style.
