Using C, initialize a two dimensional array of 3 by 4, with simple integer type data shown below. - Print the two-dimentional array. - The program should also calculate and print the sum of each row right after the last element in that row, and print the sum of each column right underneath the last element in that column. Your display should look similar to shown below where the left most colum is the sum of each row, and the last row shows the sum of each column.

Program: Using a multidimensional array, create a triangular-shaped array. You will ask the user how many lines they want to see and then create the array, fill it, and then print it. You will fill the array with one 1 in the first row, two 2’s in the second row, etc. This should work for any integer that the user enters. (Just because I am starting on 1 does not mean row 0 was skipped.)   You must: use a loop to create the array shape. You must: use nested for loops to fill the array and to print the values back to the screen. Your program should print as shown below.   Example Output:   How many lines would you like in your triangle? >>>9 1 2 2 3 3 3 4 4 4 4 5 5 5 5 5 6 6 6 6 6 6 7 7 7 7 7 7 7 8 8 8 8 8 8 8 8 9 9 9 9 9 9 9 9 9   If your code looks like the code below, it is not what I’m asking for. The code below is making a square multidimensional array, not a triangular one. The code below is just leaving certain spots empty so that it looks like a triangle. I will ask you…

Section A. Declare and initialize an array myChars containing the following characters: B, C, D, A, M, S and F.Remember to choose the correct data type for the array elements.Section B. Using a WHILE loop, output the elements of the array myChars so that they are displayed on thesame line and separated by a space. Use .length to get the length of the array.Section C. Change the last value of the array myChars to the letter X. Use .length in your code.Section D. Using a FOR loop, output the elements of the myChars array so that they are displayed on the sameline and separated by a dash (an extra dash at the end is okay). Use .length in your code.Section E. Declare an array of int of capacity 10 named thisArray.Section F. Use a FOR loop to populate the array thisArray with the following numbers 5, 10, 15, 20, 25. Thinkof a way to insert these numbers without actually writing “5” or “10” and so on, but by using the variable i ofyour FOR loop. NOTE that this is a partially-filled array and…
