Need help!!! Write the computer program in C++

implement the NAiVE-GAUSS method for solving the following NxN = 4x4 (unsymmetrical) Simultaneous Linear Equations (SLE) [A] * {x) {b) Where 0 [A] = -1 and bj Your submitted computer program(s) and its output should have the following information (b) All computer program(s)' output should print all given/input information, such as the information shown in Eqs. (2) (c) Print out (on hard paper) the UPPER triangular" matrix, and the modified/updated right-hand-side (RHS) vector b, at the end of Phase I of Naive-Gauss method. (d) Print out (on hard paper) the BACK-substitution" for the solution vector {x), at the end of Phase II of Naive- Gauss (e) Print out (on hard paper) ALL the "multiplier factors' "nag (f) Based on your computer program's outputs/results obtained by Naive-Gauss method, please print out (on hard paper) the matrices L-Lower triangular matrix, and IU]-Upper triangular matrix, that can be utilized in the L U method (g) The list of your computer program(s)' source code must be printed/included, and your computer program should be able to solve SLE with any size, say = N for the unknown vectorx)
