Question
For this assignment, you will implement the game minesweeper. This game was made popular by the Windows operating system in the early 1990s, and it has continued to be a pre-installed game until Windows 8. You can watch a video of how to play minesweeper on YouTube or read about it on Wikipedia:

The game is very simple. The object of the game is to open/reveal every cell on the board without detonating a mine. Every cell contains a number or a mine. The numbers tell you how many mines surround the cell in the horizontal, vertical, and diagonal directions, e.g. at most, 8 possible mines surrounding a cell. You can flag a cell, which helps you remember where you think there is a mine to not detonate. If you select to open/reveal a cell that has a mine, then you automatically lose the game!
Our game will be a little different, since we do not have a graphical user interface for clicking. You will run the program providing command-line arguments for the number of rows, columns, and mines in any order. Therefore, the number must be preceded by an option designator, -r for rows, -c for columns, and –m for mines.
You will then randomly distribute the mines on the board and setup the numbers describing how many adjacent mines to each cell. After that, you will display a blank board, and ask the user to flag or open a cell on the board until the user selects a cell that contains a mine (losing the game) or selects all cells free of mines (winning the game). After the user wins or loses, you will ask the user if he/she wants to play again.
If so, you must get the number of rows, columns, and mines for the new game and create a new board for a new game. BTW, you can display row and column numbers on board to make it easier to read/know which row and column to select!!!
Example run of a game:
a.o ut –r 9 –c 9 –m 10

Do you want to play again (1-yes, 2-no): 2
Requirements for game:
You must provide a usage message, if the user enters incorrect command-line arguments
You must not have functions over 15-20 lines long (-10 automatically)
You must not use global variables (-10 automatically)
You must ask the user if he/she wants to play again
(If no, then end.
If yes, then prompt for rows, cols, and mines for new game.)
You must not have any memory leaks (-10 automatically)
You must detect these errors:
(Invalid row or column to flag or open
Opening a cell that has already been opened)
Extra Credit: Recursively open all cells adjacent to 0 cell
If the user selects a cell that has no mines surrounding it, then you will help the user by recursively opening all adjacent cells to empty cells, until you reach cells with a surround mine.
Explanation / Answer
int r,c; // number of rows and columns entered from command line
int i,j; // loop indexes
int mines; // number of mines entered from command line
int main (int argc, char * argv[]) {
int gameover = 0;
char creategame[m][n]; // stores mines and adjacent integers
char todisplay[m][n]; // this is used to store everything user sees
int totalmoves;
int x,y;
int letslistmines[mines][2]; // stores coordinates of all mines
srand(time(0));
if (argc != 4) {
printf("these arer,invalid parameters. Please enter name rows columns mines. ");
return 1;
} else {
r = atoi(argv[1]);
c = atoi(argv[2]);
mines = atoi(argv[3]);
}
// this is used to initialize board to display unselected coordinate
for(i = 0; i < r; i++) {
for(j = 0; j < c; j++) {
todisplay[i][j] = '-';
creategame[i][j] = '-';
}
}
