I need part B answers not A.
In this homework, you will write a program that suggests a route to get from a starting point to a target point on a metro line. The details of the program are given below. A) Please write the following definitions: 1) Define a constant SIZE with the value 10. 2) Write a MetroStation struct that has to contain a char array of size 20, named as name (example: Haydarpasa); a double x and a double y that represent the location of a metro station. typedef it to MetroStation. 3) Write a MetroLine struct that has to contain a char array of size 20, named as color (example: red) and a MetroStation [] array of size SIZE, named as MetroStations that contains all metro stations in this metro line ordering from start to end. typedef it to MetroLine. 4) Write a MetroSystem struct that has to contain a char array of size 20, named as name (example: Istanbul) and a MetroLine [] array of size SIZE, named MetroLines that contains all metro lines in this metro system. typedef it to MetroSystem. B) Please implement the following functions: 1) Write a function equals (MetroStation s1, MetroStation s2) which returns a non-zero value if the name property of the MetroStation s1 is equal to the name property of MetroStation s2; zero otherwise. 2) Write a function addStation which takes two inputs, a MetroLine* and a MetroStation; and adds the given metro station to the end of the MetroStations [] array pointed by the MetroLine* pointer. It should return void. 3) Write a function hasStation which takes two inputs, a MetroLine and a MetroStation and returns a non-zero value if the given metro line has a metro station with the same name as the given metro station; zero otherwise. 4) Write a function getFirstStop which takes input as a MetroLine and returns the MetroStation representing the first stop of the given metro line. If there is no such station, your function should return an empty MetroStation. 5) Write a function getPreviousStop which takes two inputs, a MetroLine and a MetroStation and returns the previous Metro Station to the MetroStation
