WRITE IN C USING LINUX LIBRARIS THE OS I AM USING IS UBUNTU

Write a multithreaded program called MSquare.exe which takes 9 integer values from command line, stores those values in a 3x3 matrix, take a square of the matrix and prints the result. The program should fire off one thread for each row, i.e the program should create three threads and allocate the computation of one row to each thread. Dont provide a generic solution (because it is probably available somewhere on the net). I need a specific solution which works only for 3x3 matrix and with only three threads. A sample run of the program is given below.

nadeem@ubuntu:~/SP21/code$ ./MSquare.exe 1 2 3 4 5 6 7 8 9

Input matrix A is

1 2 3

4 5 6

7 8 9

AxA matrix is

30 36 42

66 81 96

102 126 150
