please answer asap in C please

Proper Submission [1 mark]: Modify the provided lab3.c appropriately and submit two files named lab3.c and lab3.txt to the lab 2 submission form on Blackboard. Your lab3.c file should be a properly-indented file that correctly compiles. Your lab3.txt should be a plain text file. At the top of lab3.c include your name and cite any outside sources that you used while working on this lab. This constitutes signing a statement of academic integrity and submitting a false statement is grounds for academic penalization. Part 1: Coding [10 marks). Matrices are rectangular arrays of numbers that have many applications in science, mathematics, and engineering. Each entry in a matrix has a row index and a column index typically denoted by two subscripts. For example, the matrix 110,0 20,1 20.2 01.0 011 01.2 : : an-1,0 An-1.1 an-1.2 has n rows (indexed by an integer from 0 to n - 1) and 3 columns (indexed by an integer from 0 to 2) and is said to be an n x 3 matrix. In C, matrices can be stored as a two-dimensional array. For example, the declaration int a[n][3]; allocates enough memory to store an n x 3 matrix. During the lab, the assistants will go over multi-dimensional arrays and how to implement a function matrix_equals that tests if two given matrices are equal (note that arrays cannot be compared for equality using the == operator). They will describe how array elements can be accessed either using indexing (the [] operator) or using pointer arithmetic. The sum of two matrices of the same size can be formed by adding together the entries that appear in the same locations (i.e., entrywise addition). Complete an implementation of the following prototype for a function that computes matrix addition. W matrix_add(n, a, b, c) computes the sum of the n x 3 matrices a and b; the result is stored in the n x 3 matrix c // requires: n >= 1 void matrix_add (const int n, const int a [][3], const int b[][3], int c[] [3]); Next, complete implementations of the following two functions which perform the matrix operation that is stated in the function purpose statements. In the implementation of negate_row you cannot use the indexing operator [] and must instead use pointer arithmetic. // negate_column (n, c, a) negates the entries in column c of the n x 3 // matrix a W requires: n >= 1, 0
