In a 3x3 array using a loop print characters (not integers) of 1-9. Now write function to ask user to input (‘X’ or ‘O’) in each of the selected position 1-9 in the array. If the user selects X in one of the positions then it would be O in the next selection and print the 3x3 array in each of the total 9 insertions. No repetition in any position is allowed.

It's important to note that the name of an array by itself is really a pointer to the first element of the array. Therefore passing an array to function is simple since you can just specify the name of the array. Are these statements true?

Create an array called sales to monitor one week's worth of sales over the course of two months. Assign sales data to the array's elements. Then, in a loop, compute the average sales for the one week of each of the two months that are recorded in the array.

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...

The type size_t represents an unsigned integral type, which is recommended for any variable that represents an array's size or an array's indices. Select one: O True False
