I think hitting a C++ tutorial on functions would do this OP a LOT of good.

Thank you for your comments. I will come back to you guys here, once I understand.


Dude, by seeing the code you have provided I can tell you that you have forgotten to start the serial communication, Serial.begin(9600);
Second mistake, you must call the function. Calling a function means to "trigger" it.
void setup(){

void loop(){
  int x =0;
  if( x==0){
    cheesecake();  //cheesecake() calls the   
                               //function called cheesecake

void cheesecake(){               
 //after calling cheesecake you come here
 //here do whatever you want
