In C Programmming,

Assume a file, called data.txt, resides in the local directory. (The data.txt file can be downloaded from ELMs; follow the link under Homework #1). This file contains integers for a matrix and a vector. The matrix is specified in 10 lines of 10 integers each, providing the values for a 10 x 10 matrix. (Each line is terminated by a new-line character, and within each line the integers are separated by white space characters). After the matrix values, a vector is specified in a single line of 10 integers, providing the values for a 10- element vector. Write a C program that opens the data.txt file, reads in the 10 x 10 matrix and the 10-element vector into arrays, and then computes the matrix-vector product. The matrix-vector product of an NxN input matrix and an N-element input vector is itself an N-element vector in which the ith element of the solution vector is the inner product of the ith row of the input matrix and input vector. (The inner product is the sum of the products between pairwise elements of 2 vectors). After computing the matrix-vector product, your program should print the resulting vec- tor. Here is the sample output of the program: z: hw1.2 554912 121387 17341 52023 138728 173410 398843 190751 242774 537571
