Write a function called "AddRows" that accepts two parameters M1: a matrix of size 6x4 elements of type integer A1: a one dimensional array of size 4. For each column in M1, the function will calculate and store in the corresponding element of array A1, the sum of the elements located in odd rows of M1. For example if M1 7 6 12 E 4 9 7 3 6 8 5 de 10 5 10 2 00 20:19 4 in 3 s 6 10 12 12 E Then Al N Then A1 = 18 31 22 17 Use the editor to format your answer 3 III. Question 3 15 Points Given a text file containing unknown number of lines, each line containing three integer values representing the height of a building in (Yard foot inches) separated by space. Write a well-documented C++ program that 1. Reads the three values from the file. 2. If any of the read values is greater than 2000. prints on the screen an error message: "Error: invalid building tength.r. 3. Otherwise, calculates the building length in inches, where one yard is 3 feet and foot is 12 inches 4. Sends to another file both length values the read and the calculated as shown below. 5. Repeats steps (1-4) until a negative value is encountered, . For example. If the read values are (7126), then your program must send to a new file the following: The height of a building in YD:FTiIN format = 71:2:6 The height of a building in inches = 2586 Use the editor to format your answer BE Question 4 1.5 Points
