1. Choose the correct forum for your message. Posting a VB.NET question in the C++ forum will end in tears.
   
   
2. Be specific! Don't ask "can someone send me the code to create an application that does 'X'. Pinpoint exactly what it is you need help with.
   
   
3. Keep the subject line brief, but descriptive. eg "File Serialization problem"
   
   
4. Keep the question as brief as possible. If you have to include code, include the smallest snippet of code you can.
   
   
5. Be careful when including code that you haven't made a typo. Typing mistakes can become the focal point instead of the actual question you asked.
   
   
6. Do not remove or empty a message if others have replied. Keep the thread intact and available for others to search and read. If your problem was answered then edit your message and add "[Solved]" to the subject line of the original post, and cast an approval vote to the one or several answers that really helped you.
   
   
7. If you are posting source code with your question, place it inside <pre></pre> tags. We advise you also check the "Encode HTML tags when pasting" checkbox before pasting anything inside the PRE block, and make sure "Ignore HTML tags in this message" check box is unchecked.
   
   
8. Be courteous and DON'T SHOUT. Everyone here helps because they enjoy helping others, not because it's their job.
   
   
9. Please do not post links to your question in one forum from another, unrelated forum (such as the lounge). It will be deleted.
   
   
10. Do not be abusive, offensive, inappropriate or harass anyone on the boards. Doing so will get you kicked off and banned. Play nice.
    
    
11. If you have a school or university assignment, assume that your teacher or lecturer is also reading these forums.
    
    
12. No advertising or soliciting.
    
    
13. We reserve the right to move your posts to a more appropriate forum or to delete anything deemed inappropriate or illegal.

1. Read the question carefully
   
   
2. Understand that English isn't everyone's first language so be lenient of bad spelling and grammar
   
   
3. If a question is poorly phrased then either ask for clarification, ignore it, or mark it down. Insults are not welcome
   
   
4. If the question is inappropriate then click the 'vote to remove message' button

In this game you can develop whatever technologies. But you want to implement smile API.
Smile API just provide image and Solutions(Solution always come 1-9 Numbers ). image have simple maths quiz.
Every Time you call smile API ,Image and solution will be change.
You can do like quiz application. You want to validate that solution with user's answer.

You want to add this 3 components in this game
1.Software architecture- it's like model view controller, clean Architecture
2.even driven architecture- it's like GUI (login, Register)and buttons.
3.Interoperability - it's mean Use Smile Api
And you can get extra marks for Extra features. Question is the image .API response should be the solution.

Quote:

When the Login button is pressed, initialize the game and call the API .Send the HTTP Get Request using API .After Login starts GUI .When initialized the game appears the question . When the user answers the question, Solution becomes the API Response and passes the data to the JSON object .Validate the Solution with the user's answer .If the user's input is equal to the solution (calculation is correct) the user can go to the next level and increase the score and also call the API .

Quote:

When calling the API get the data and divide into the string variables .In this need JSON array() instead of JSON object

add_shortcode( 'MODELL', 'modell_shortcode' );
function modell_shortcode() {
$terms = get_the_terms( array(
      'post_type'     => 'fahrzeuge',
      'taxonomy'      => 'marken',
      'hide_empty' => false,
 ) );
return ucwords($terms[1]->slug);
}

Add the following code however when executing it does not show the page
