Use fscanf() to read the data from HW4Problem2.txt into a matrix called B. Note that you need to use fgets() to avoid the header row. Make a note of B’s dimensions. Next, do the following
- a) Print the matrix B with each element in the same position as it was in the text file, but with integer format for the 1st and 3rd column, fix-point format with a precision of 2 for the 2nd column, and exponential format with a precision of 5 for the last column. Put two tabs (t) between each column.
- b) Multiply each element of the first column in HW4Problem2.txt by each element of the 3rd column of HW4Problem2.txt and store the result in a column vector (5×1) called c. WARNING: you better compare what you stored in B and what is in HW4Problem2.txt.
- c) Do array multiplication with the values in B (4×5) times c, and store the result in a 4×1 vector called d.
- d) Create a 4×2 array called M. The first column of M is the index of each row of d and the second column of M is the
- corresponding value of d.
- e) Use one fprintf() call to output 4 lines, each with the following form:
- “The value of d at the i index of d is x.xxxxxxE+yy.”
- where i ranges from 1 to 4 and represents the value of the index for the value of d that is being printed.
