Using C++. ... Engineering P6.15 You are given a two-dimensional array of values that give the height of a terrain at different points in a square. Write a functionvoid flood_map(double heights [10] [10], double water_level)that prints out a flood map, showing which of the points in the terrain would be flooded if the water level was the given value. In the flood map, print a* for each floodedpoint and a space for each point that is not flooded.Here is a sample map:Ⓒnicolamargaret/iStockphoto.Then write a program that reads one hundred terrain height values and shows how the terrain gets flooded when the water level increases in ten steps from the lowest pointin the terrain to the highest. DescriptionThis lab assignment is loosely based on the End-of-Chapter Exercises Engineering P6.15. (In mybook that is on page EX6-3 which is the page before page 223). Review the instructions therefor some helpful information though there are differences expected for this lab project. Yourprogram should allow the user to enter a flood level, provide the appropriate map, and alsoprovide the lowest, highest, and average water levels. The average water level should be tothree decimal places, to the thousandth, not the tenth. The water level is, forsubmerged/flooded points on the map only, the depth of the water at that point. That is, theflood level minus the terrain height. Note that a point is only submerged/flooded if the floodlevel is greater than the terrain height.Write a program that willa) Greet the user by name. Provide the user with a brief description of the program.b) Invite the user to try the program. Allow user to choose.c) Ask the user for the flood-level.d) Based on the given input, provide a map.a. In your map, indicate the area that is NOT flooded, the area at the flood level,and the area that is flooded. Decide on meaningful symbols to use.b. Provide the lowest water level and the location(s).c. Provide the highest water level and the location(s).d. Provide the average water levele) Include some data validation (input checks) in case your user makes a mistake typingor misunderstands the prompt.f) Allow the user to repeat or quit.g) End your program appropriately and in a friendly way.

HISTORY OF C++:- C++ was invented in 1979 by Bjarne Stroustrup while working on his PhD thesis at Bell Labs. Stroustrup originally designed C++ as a set of extensions to the programming language C, which he wanted to use for systems programming. These extensions included classes, operator overloading, inlining, and default arguments. C++ was released for commercial use in 1985, but it was not yet standardized. In order to standardize the language, a committee was formed in 1988 and the first official standard was published in 1998. C++ has undergone several major revisions since it was first published. The most recent standard is C++11, which was published in 2011. C++ is a powerful programming language that is used in many different domains, such as systems programming, scientific computing, and game development.THE CODE IS SHOWN BELOW:_ #include <iostream>#include <string>#include <vector> class Terrain{ public: std::vector<std::vector<double>> terrain; Terrain(std::vector<std::vector<double>> &heights) { terrain = heights; } void printFloodMap(double waterLevel) { std::cout << "Flood Map" << std::endl; for (int i = 0; i < terrain.size(); i++) { std::cout << "" << std::endl; for (int j = 0; j < terrain.size(); j++) { if (terrain[i][j] > waterLevel) { std::cout << "*"; } else { std::cout << " "; } } } } static void main(std::vector<std::string> &args) { std::vector<std::vector<double>> heights{{12.1, 10, 14.0, 5.2, 3.2, 11.6, 8.2, 6.9, 7.9, 10}, {11.1, 4, 7.0, 12.2, 11.2, 11.4, 1.2, 7.0, 7.2, 5.4}, {5.7, 8, 6.0, 12.2, 11.2, 11.4, 1.2, 7.0, 7.2, 5.4}, {9.8, 5, 14.0, 12.2, 11.2, 11.4, 1.2, 7.0, 7.2, 5.4}, {31, 1, 15.0, 12.2, 11.2, 71.4, 7.2, 3.0, 5.2, 5.4}, {6.1, 9, 6.0, 17.2, 11.2, 19.4, 1.2, 8.0, 9.2, 56.4}, {9.3, 10, 9.8, 0, 14.2, 19.2, 16.4, 45.2, 30.0, 44.2}, {4.1, 45.9, 7.0, 62.2, 61.2, 1.4, 7.2, 8.0, 9.2, 4.4}, {3.2, 7, 7.0, 11.2, 91.2, 1.4, 11.2, 72.0, 67.2, 8.4}, {11.9, 67, 7.0, 8.2, 19.2, 31.4, 11.2, 77.0, 2.2, 7.4}}; Terrain* T = new Terrain(heights); T->printFloodMap(5.2); }};int main(int argc, char **argv){ std::vector<std::string> parameter(argv + 1, argv + argc); Terrain::main(parameter); return 0;};THE OUTPUT IS SHOWN IN BELOW OF THE ABOVE CODE:-
