Write a C or C program A6p2.c(pp) that accepts one command line argument which is an integer n between 2 and 4 inclusive. Generate 60 random integers between 1 and 49 inclusive and store them in a 5 by 12 two dimensional integer array (i. e.,int a[5][12];). Use pthread to create n threads to square all 60 array elements in place. You should divide this update task among the n threads as evenly as possible. Print the array both before and after the update separately as 5 by 12 matrices. Hint: it is dangerous to have code to print stuff in your thread function(s). Note: if you do not use pthread to divide the update task among the threads, you may get zero points. A sample run of the programs in 1 and 2 is shown below. You do NOT need to submit screen shots. Instead submit your source file.
