Write a C program to read the values of a 6 x 6 2D array from a file, and then produce an output file that contains the transpose of the array. Array values are decimal. The input and output files contain one array row on each text line. a.)Extend the previous exercise to count the total number of duplicate elements in the 2D array. b.) Extend the program in exercise 1 to count the frequency of each element of the 2D array. c.)Extend the program in quesyion1 to separate the positive and negative values of the 2D array in two separate 1D arrays. Save the two 1D arrays in an output text file.
