Specifications

• Your instructor should supply you with a file named email_list.txt that contains a list of email addresses in this format:

james\tbutler\[email protected]

josephine\tdarakjy\[email protected]

art\tvenere\[email protected]

• Your instructor should supply you with a file named email_template.txt that provides a template for a mass email in a file like this:

To:      {email}
From:    [email protected]
Subject: Deals!

Hi {first_name},

• When the program starts, it should read the email addresses and first names from the file, merge them into the mass email template, and display the results on the console.
• All email addresses should be converted to lowercase.
• All first names should be converted to title case.
• If you add names to the list of email addresses, the program should create more emails.
• If you modify the template, the program should change the content of the email that’s created.

        fname = toLower(fname);

        fname[0] = toupper(fname[0]);

        email = toLower(email);

        temp_copy = temp;

        while((pos=temp_copy.find("{email}"))!=string::npos){

            temp_copy.replace(pos, 7, email);

        }

        while((pos=temp_copy.find("{first_name}"))!=string::npos){

            temp_copy.replace(pos, 12, fname);

        }

        cout<<"========================================================"<<endl;

        cout<<temp_copy;

    }

    in.close();

    return 0;

}

string toLower(const string &str){

    string result = "";

    for(int i=0; i<str.size(); i++){

        result += tolower(str[i]);
