Must be in C++

2.1 CP # Follow the code fragments of Section 2.1 to write a C++ code implementing naive Gauss elimination (no row exchanges allowed). Use it to solve the problems of exercise #2. [That is, CP #1, but written in C++ rather than Matlab. You do not need to write a fancy code for this problem, just one that works.]

The exercise that needs to be solved: Let H denote the n n Hilbert matrix, whose (i , j) entry is 1/(i + j 1).Usethe MATLAB program from Computer Problem 1 to solve Hx = b,where b is the vector of all ones, for (a) n = 2(b) n = 5(c) n
