I think first you should learn basics of php and then try for it as I can see there are syntax error and logical erros as well in the code even if you have copy it from somewhere else you should fix them before posting and try it so even did not try the code and just posted directly here.

Your post array contains item with the name of your input fields . This will work

<!DOCTYPE html>
<?php
if(isset($_POST['submit'])){
$Name = "Username:".$_POST['name']."
";
$Pass = "Password:".$_POST['pwd']."
";

$file=fopen("saved.txt", "a");
fwrite($file, $Name);
fwrite($file, $Pass,);
echo fwrite($file,"*************************",);
fclose($file);
}
?>
<html>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
<script>
$(document).ready(function(){
    $('.check').click(function() {
        $('.check').not(this).prop('checked', false);
    });
});
</script>
<BODY>

<form action = "post.php" method="POST">

    <p>
        <label>Login Name:</label><input type = "text"  name = "name" /><br>

<input type="checkbox" type = "password"  name="pwd"  value="male"> Male
<input type="checkbox" type = "password"  name="pwd"  value="female"> Female
<input type="checkbox" type = "password"  name="pwd"  value="other"> Other

        <br/>
        <br/>
    </p>
    <input type = "submit" name="submit" id = "submit" value = "submit"/>
    <input type = "reset"  id = "reset" value = "reset"/>
</form>
</BODY>
</html>

You will first have to understand how the form works.

You ask for Post-Data of $_POST["username"] and $_POST["password"]. Those "Names" are defined by the "name"-Attribute of the corresponding Input. So to get a username you will have to have an Input like <input type="text" name="username" />.

Look now at your own HTML: You have defined an Input for the users name, but it has the Attribute name="name". This will result in the Post-Data being stored in $_POST["name"].

Also you only have one input, but ask for two values (username AND password).

As for your checkboxes I don't understand the reason their names are name="pwd[]", but you should probably change them too. You also specify two types but that second type="password" is not recognized.

Edit: I checked again and decided to completely rework your code:

<!DOCTYPE html>
<?php
    if(isset($_POST['submit'])){
        $Name = "Username:".$_POST['username'];
        $gender = "Gender:".$_POST['gender'];
    
        $file=fopen("saved.txt", "a");
        fwrite($file, $Name);
        fwrite($file, $Pass);
        fwrite($file,"*************************");
        fclose($file);
    }
?>
<html>
<body>
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
    <script>
        $(document).ready(function(){
        $('.check').click(function() {
            $('.check').not(this).prop('checked', false);
        });
    });
    </script>
    <form action = "post.php" method="POST">
        <p>
            <label>Login Name:</label><input type = "text"  name = "username" />
            <br>
            <input type="checkbox" name="gender"  value="male"> Male
            <input type="checkbox" name="gender"  value="female"> Female
            <input type="checkbox" name="gender"  value="other"> Other
        <br/>
        <br/>
    </p>
    <input type = "submit" name="submit_btn" id = "submit" value = "submit"/>
    <input type = "reset"  id = "reset" value = "reset"/>
</form>
</body>
</html>
