Please do not copy and paste the answer that Chegg has for this question. I have asked this question already and the expert copied and pasted the answer from Chegg. Please actually solve this problem, or I'll just have to cancel my Bartleby subscription.C++ Question Hello, Please create the correct code based on the attached requirement picture. Please make sure the code is functional. Please do not use any Advanced C++ syntax. Thank you. Write a program that allows the user to create and maintain a list of contacts in a file named MyContacts.txt. Eachcontact will have a name and a phone number. In the file, each line should have a contact's name followed by theirphone number. Note: To simplify things, for this assignment, you may assume that every contact's name will just be asingle word (i.e. no last names)For example, if your file has two contacts in it, it might look something like this:Bob 555-1234Jill 555-4321Recall that if you try to open a file for reading before it exists, the program will crash. Therefore, assume the user willfirst try to add a contact as their first option (i.e. I won't try to print the list or print a number first when I'm testing yourcode). In the addContact method, when you open a file for appending, it will be created for you.In a while loop, continually ask the user what option they would like to choose. Each option (other than the quit option)should call a function which performs a specific task. Their options are:1. Call a function named printList: This function should print out the data in MyContacts.txt in the following way:Contact 1: Bob Phone Number: 555-1234Contact 2: Jill Phone Number: 555-4321etc.2. Call a function named findNumber which will find the phone number of a specific contact by asking the user enter aname. If the name is found in MyContacts.txt, return its corresponding phone number. Otherwise, return the emptystring (quote-quote). Back in main, if a number is returned from findNumber, print it out. If the empty string is returned,tell the user the contact doesn't exit.3. Call a function named addContact which will allow the user to add a contact to the file. In this function, ask the userto enter a name and phone number and then append these values to the end of MyContacts.txt. Again, you may assumethat the user will only enter single-word names.4. Quit the program

code is utilitarian#include <iostream>#include <fstream>using namespace std; void addContact(){ string name, number; cout << "Enter Name and Phone Number" << endl; cin >> name; cin >> number; ofstream file_out; file_out.open("a.txt", std::ios_base::app); file_out << name << " " << number << endl;} void printList(){ fstream newfile; newfile.open("a.txt",ios::in); if (newfile.is_open()){ string tp; int count=1; while(getline(newfile, tp)){ size_t found = tp.find(" "); string name=""; string phone=""; for(int i=0; i<tp.length(); i++){ if(i<found) name+=tp[i]; else if(i>found) phone+=tp[i]; } cout << "Contact " << count << ": " << name << " Phone Number: " << phone << endl; count+=1; } } newfile.close();} void findNumber(){ string inp; cout << "Enter name: " << endl; cin >> inp; fstream newfile; newfile.open("a.txt",ios::in); if (newfile.is_open()){ string tp; int flag=0; while(getline(newfile, tp)){ size_t found = tp.find(" "); string name=""; string phone=""; for(int i=0; i<tp.length(); i++){ if(i<found) name+=tp[i]; else if(i>found) phone+=tp[i]; } if(inp==name){ flag=1; cout << "Contact: " << name << " Phone Number: " << phone << endl; } } if(flag==0) cout << "Contact doesn't exist" << endl; } newfile.close();} int main(){ int option=0; do{ printf("Enter\n1. Add Contact\n2. Print List\n3. Find Number\n4. Exit\n"); cin >> option; if(option==1) addContact(); else if(option==2) printList(); else if(option==3) findNumber(); }while(option!=4); return 0;}
