usernameExsist function c++ Object-orienten progrmming - c++

Question

I have a class:
class Account {
private:
string name;
unsigned int age;
string username;
string password;
};
In my main program I need to make a bool usernameExsist(Account* userAccount, Account* acountList[], int numberOfElements) function that returns true if the name is found. But I have problems with the arrays and the implementation.I entered some information in the class: Account first=Account("Max", 18,"maxx34","12345adc");Can someone help me with the implementation?! Thanks.

You can use class vector which relieve you from the burden of arrays and size...
Here is an example that you could modify to meet your needs:
#include <iostream>
#include <vector>
#include <string>
using namespace std;
class Account {
public:
Account(string, unsigned int, string, string);
//private: // in your example un-comment private and provide public getters instead.
string name;
unsigned int age;
string username;
string password;
};
Account::Account(string Name, unsigned int Age, string UserName, string Password) :
name(Name), age(Age), username(UserName), password(Password){
}
bool usernameExsist(string, vector<Account>);
int main(){
std::vector< Account > vec;
string name;
unsigned int age;
string username;
string password;
while(1){
cout << "name: ";
getline(cin, name);
cin.ignore();
cout << "Age: ";
cin >> age;
if(!age || age < 0)
break;
cin.ignore();
cout << endl;
cout << "username: ";
getline(cin, username);
cin.ignore();
cout << endl;
cout << "password: ";
getline(cin, password);
cout << endl;
cin.ignore();
Account a(name, age, username, password);
vec.push_back(a);
}
cout << usernameExsist("Max", vec) << endl;
cout << endl;
return 0;
}
bool usernameExsist(string name, vector<Account> vec){
const int size = vec.size();
for(int i(0); i != size; ++i)
if(name == vec[i].name){
cout << "Found at: " << i << endl;
return true;
}
return false;
}
