'Var' does not name a type!

I don't have much experience in C++ programming. I'm getting this error

'z' does not name a type!!!

which I have't seen in MATLAB or python... What's wrong??? It is so simple!!!

float x=10; float y=50; float z;

z=x*y;



void setup() {

  // put your setup code here, to run once:

}



void loop() {

  // put your main code here, to run repeatedly:

}

You cannot put an expression statement outside a function. Only the variable declarations can be placed outside functions (and those variables are called globals/global variables).

Try the following:

float x=10; float y=50; float z;





void setup() {

  // put your setup code here, to run once:

  z=x*y;

}



void loop() {

  // put your main code here, to run repeatedly:

}

You can put an expression outside a function (e.g. float z=x*y; does have an expression x*y in it, and may appear in namespace scope). What you can't put there is an expression statement (or any other type of statements).
