Problem $2.$ answer in c language ou are given a task to implement a hierarchical data structure rep$-$resenting cities, regions, countries, and continents. Your implementation should allow youto create instances of these entities, link them appropriately, and print specific hierarchicalinformation.The structures and relationships are as follows:$$EachCitybelongs to aRegion.$$EachRegioncontains multipleCitiesand belongs to aCountry.$$EachCountrycontains multipleRegionsand belongs to one or moreContinents.$$EachContinentcontains one or moreCountries.Here are the specific requirements:$1.$ Define structures forCity,Region,Country, andContinent.$$Cityshould have the variables below:char name$[50]->$City nameint population$->$Population of the city$$Regionshould have the variables below:char name$[50]->$Region nameint population$->$Total population of the cities in the regionint numcities$->$Number of cities that the region has$$Countryshould have the variables below:char name$[50]->$Country nameint population$->$Total population of the cities in the countryint numregions$->$Number of regions that the country hasint numcontinents$->$Number of continents that the country has$$Continentshould have the variables below:char name$[50]>$Continent nameint population$->$Total population of the cities in the continentint numcountries$->$Number of countries that the continent has$2.$ Create instances ofCity,Region,Country, andContinentand establish their rela$-$tionships.$$Continentshould point toCountry$\mathrm{.}4$

$$Countryshould point toContinentandRegion.$$Regionshould point toCountryandCity.$$Cityshould point toRegion$\mathrm{.}3.$ Populate the data:$$Include two continents, named $$Europe$$ and $$Asia$.$Asia contains one country, $$Turkey$.$Europe contains two countries, $$Turkey$$ and $$France$.$France has multiple regions, $$Ile$-$de$-$France$$ and $$Nouvelle$-$Aquitaine$.$Turkey has multiple regions, $$Marmara$$ and $$Ege$.$Paris and Yvelines $($two cities in France$)$ are in Ile$-$de$-$France, and the correspond$-$ing populations are $2161000$ and $1437000,$ respectively.$$Bordeaux $($a city in France with $249712$ population$)$ is in Nouvelle$-$Aquitaine.$$Izmir $($population: $4367000)$ and Manisa $($population: $1430000)$ are in Ege region,Turkey.$$Istanbul $($population: $15460000)$ is in Marmara region, Turkey$\mathrm{.}4.$ Ensure proper memory allocation for dynamic data$\mathrm{.}5.$ Name the variables so that the program will be able to print the following hierarchicalinformation:$1$p r i n t f $($ Continent : $\%$s $.$
