Question

/// c ++ question plz help me fix this not a new code 
and explain to me plz

///   

Write a function to verify the format of an email address:

bool VeryifyEmail(char email[ ]);

Do NOT parse the email array once character at a time. Use cstring functions to do most of the work. Take a look at the available cstring and string class functions on cplusplus website.

Use a two dimensional array to store the acceptable top domain names: "COM", "ORG", "NET", "US", "CN", "CA",etc.

/////

I didnt do the 2D array, please also put it in the code thanks
//////

#include <iostream>

#include <string>

bool VeryfyEmail(char email);

bool isCharacter(char Character);

bool isNumber(char Character);

using namespace std;

int main()

{

    // set the email you wanna Verify

    string email;

    string test;

    cout << " enter an Email: " << endl;

    getline(cin,email);

    test = email;

    // output the email you entered

    cout << "the email you enter is: " << endl;

    cout << email;

    cout << endl;

    /////////////////////////////////////////////

    // Verfy email

    if (VeryfyEmail(test))

    {

        cout << " your email is vaild." << endl<< endl;

    }

    else

    {

        cout << " your email is invaild. " << endl<< endl;

    }

    return 0;

}

bool VeryfyEmail(char email)

{

    if(!email) // if cannot read emial

    {

        return 0;

    }

    if(!isCharacter(email[0]))

    {

        return 0;

        // first character not a character a-z A-Z

    }

    int atOffset = -1;

    int Dotoffset = -1;

    int length =  strlen(email); //length

    for (int i =0; i < length; i++)

    return 0;

    }

    return !(Dotoffset >= ((int)length -1 )); // check there is some other letters after the Dot

}

bool isCharacter(char Character)

{

    return ((Character >= 'a' && Character <= 'z') || (Character >='A' && Character <= 'Z'));

    // check between a-z or A-Z

}

bool isNumber(char Character)

{

    return (Character>='0' && Character <= '9');

    //between 0-9

}
