I just need a cod

Write a general computer program (in C, C++ or Java) to convert a vector in one coordinate systems to a vector in another coordinate systems e.g. Cartesian to cylindrical, cartesian to spherical: spherical to Cartesian, cylindrical to Cartesian system, cylindrical to spherical system, or spherical to cylindrical system) using matrix representation of the conversion at a given point. Follow the "Formal for Computer Assignment Report" in preparing this report. The report should have a cover page, problem statement and must be neatly prepared using only an 8.5" by 11" engineering paper. All pages must be stapled and sequentially numbered. Figures, flow graphs, and tables must be properly labeled and tilled. The report must be signed and dated. References should be in proper format and cited in the report. Using your computer program above, express a uniform field F = 4 x y^2 a_rho + y x^2 a_z in cylindrical coordinates (a) to Cartesian Coordinates at P (2, 3, 2). Verify your results by hand calculations
