Project $5$: Galactic Fuel w$/$ClassesObjectives$1.$ More practice designing and implementing a class in C$++2.$ More practice working with and indexing arrays$\mathrm{.}3.$ More practice working with files.BackgroundIn the outer reaches of the Andromeda Galaxy, the Zentharians, a highly advanced race ofinterstellar navigators, embark on their annual Quantum Fuel Expedition to secure the hyper$-$dense dark energy crystals essential for powering their formidable battleships during theGalactic War Games. The crystals, known for their exceptional energy yield, are scatteredacross the perilous Dark Quantum Nebula, and the Zentharians must traverse this chaoticregion to harvest their fuel.Navigating the inky depths of the nebula is no small feat, and each Zentharian diligently logsthe quantum fuel content of the crystals they procure, documenting the data in their QuantumEnergy Ledger. Due to the nebula's interference with advanced communication technologies,the Zentharians rely on ancient, yet reliable, manual recording methods.For instance, as the Quantum Fuel Expedition progresses, the Zentharian ledger might read asfollows:$1112223334005506007008309101001$This ledger signifies the quantum fuel carried by five Zentharian navigators: The first Zentharian is carrying dark energy crystals with a quantum fuel content of $111,222,$ and $333$ units, totaling $666$ units. The second Zentharian is carrying a single dark energy crystal with a quantum fuelcontent of $400$ units. The third Zentharian is carrying dark energy crystals with a quantum fuel content of $550$and $600$ units, totaling $1150$ units. The fourth Zentharian is carrying dark energy crystals with a quantum fuel content of$700,830,$ and $910$ units, totaling $2440$ units. The fifth Zentharian is carrying a single dark energy crystal with a quantum fuel contentof $1001$ units.In the event that the Zentharians encounter hostile forces during the Galactic War Games andrequire additional quantum fuel for their battleships, they must identify which Zentharian toapproach. Specifically, they aim to determine the Zentharian carrying the most quantum fuel.In the example above, this would be the fourth Zentharian with a total quantum fuel contentof $2440$ units.The AssignmentYour task is to write a C$++$ program that will process a ledger file to pinpoint the Zenthariannavigator carrying the most quantum fuel and calculate the total quantum fuel they aretransporting. The ledger files will have no more than $1000$ groups of data aka $1000$Zentharians with mutiple crystals $($but no more than $20)$ of fuel. May the quantum anomaliesguide your calculations!Requirements$1.$ Use as your filenames: main.cpp$,$ Zentharian.cpp$,$ Zentharian.h$2.$ You must design a class for the Zentharian that should contain the following: Data: minimally the individual crystal values in an array as the data although youmay wish to include other data members to make the main program easier toimplement. Member Functions:methods you determine are necessary to interact with the datamembers, and at least one overloaded comparison operator $($I recommend $>)$ forcomparing Zentharian objects. A global constant in the main file for the maximum number of Zentharians A global constant in the head file for the maximum number of Crystals$3.$ All output should be spelled, spaced, and formatted according to the sample runs below.Hints Recall from the notes there is a function called std::stoi$()$ in the string header that willaccept a string and return an integer value Also, remember that an empty string is $""$ and that std::getline$()$ throws out the newlinecharacter. You may wish to refer to the example code posted for the $8$ Ball and Item examples forhelp.Sample RunsSample Run $1$Enter ledger file: sample.datZentharian $4$ has $3$ crystals worth$700830910$fuel each.
