$4\mathrm{.}2$ Main Function int main$($int argc, char $**$argv$)$; $$ Arguments: This function have should have the two defined arguments above. $$ Output: This function should have no output. $$ Return: A simple integer. Just $0.$ Disclaimer: The program will be passing in a single file name as an argument. $4\mathrm{.}31$D Array Creation Context: Similar to lab$3,$ you will be writing a function that generates a list of integers initialized to $1$s$.$ createOneDimensionalArray$()$; $$ Arguments: This function will have one argument. $$ size: an integer representing the length of the new array $$ Output: This function will output one line. The size of the array that was created. $$Array of size # is created.$$ where # is the size of the array. $$ Return: A pointer to the newly created array. $44\mathrm{.}4$ Matrix Creation For this function, you are expected to create a matrix. A matrix is a $2$D array of integers. All values will be initialized to $1.$ Details regarding this matrix will come from the file. createMatrix$()$; $$ Arguments: This function will have two arguments. $$ columns: an integer representing the number of columns $$ rows: an integer representing the number of rows $$ Output: This function will output two lines: the size and the list of values. $$Matrix of size $($X$,$ Y$)$ is created.$$ where X is the number of rows and Y is the number of columns. $$ Return: A pointer to the newly created matrix. $$ Disclaimer: DRY must be applied here. $4\mathrm{.}5$ Read File Containing Matrix Data For this function, you are expected to read in a file that contains information on two matrices. readFile$()$; $$ Arguments: This function will have one argument. $$ fileName: a char pointer representing the name of the file $$ Output: This function will output the following line, two times. $$Matrix of size $($X$,$ Y$)$ is found.$$ where X is the number of rows and Y is the number of columns. $$ Since the file has two matrices inside of it$,$ you are expected to print the dimensions of the arrays that were found. $$ Return: A rating between $1$ and $5$ representing the difficulty of this function $$ Reminder: Please refer to the example input above on the structure of the text file. $4\mathrm{.}6$ Matrix Addition For this function, you are expected to add two matrices together. The first matrix will be a new initialized matrix from the function above and the second will be read from a file. You cannot assume the matrices will be of the same size. addMatrices$()$; $5$ Arguments: This function will have four arguments. $$ defaultMatrix: an int double pointer representing the default matrix $$ readInMatrix: an int double pointer representing matrix from the file $$ rows: an integer representing the number of rows $$ cols: an integer representing the number of columns $$ Output: This function will output the result of the addition, when possible. $$# # #$$ where there will be X number of rows and Y number of columns. $$ Return: an int double pointer representing the summed matrix $$ Error: If not the same size, you must print the following line: $$Matrices are not the same size. Cannot add.$4\mathrm{.}7$ Diagonal Sum of Matrix For this function, you are expected to get the main diagonal sum of the passed in matrix. The main diagonal is the diagonal that starts from the top left corner and goes to the bottom right corner. You cannot assume the matrix will be square. The definition of a square matrix is that the number of rows is equal to the number of columns. computeDiagonalSum$()$; $6$ Arguments: This function will have three arguments. $$ matrix: an integer double pointer representing the matrix $$ rows: an integer representing the number of rows $$ cols: an integer representing the number of columns $$ Output: This function will output sum of the main diagonal, when possible. $$Diagonal Sum is: X$$ where X is the sum of the main diagonal. $$ Return: A rating between $1$ and $5$ representing the difficulty of this function $$ First Error: If not a square, you must print the following line: $$Matrix is not square. Cannot compute diagonal sum.$$ Second Error: If add matrices failed, you must print the following line: $$Matrices were not able to be added together.$$ Disclaimer: The matrix used for this function will be the result of addMatrices $4\mathrm{.}8$ EXTRA CREDIT: Tracking Memory For this function, you are expected a two$-$fold mission: $$ Print the number of bytes the matrix from addMatrices contains. $$ Ensure you have free$$d all memory correctly. No points will be given if you printed the bytes but did not free accordingly. collectBytes$()$; $$ Arguments: This function will have three arguments. $$ matrix: an integer double pointer representing the matrix $$ rows: an integer representing the number of rows $$ cols: an integer representing the number of columns $$ Output: This function will output the number of bytes the matrix is $$Total bytes of matrix: X$$ where X is the sum of all bytes in the matrix. $$ Return: A rating between $1$ and $5$ representing the difficulty of this function $$ Disclaimer: The matrix used for this function will be the result of
