EXERCISE $(O)$

ABC Grid

For this activity you will create the program abc$\_$grid.c $.$

The program will create a cascading pattern in the form of a grid of letters. First the program will ask the user to choose a grid size by entering the number of rows and then the number of columns. The program will then ask for a starting letter and the starting coordinates for this letter. This is where the pattern will start from.

In the example below the starting letter is $Y.$ Lets say its starting position was $[x][y]$ where $x$ and $y$ are some starting co$-$ordinates. The letter following $Y$ in the alphabet is $Z$ and hence the immediate surrounding positions $([x+1][y],[x-1][y],[x][y+1],[x][y+1])$ are $z.$ This pattern now continues from $z$ where the next letter is A and so on to B$.$ This pattern will continue until the grid has been filled!Examples
