Splitting a program across multiple files

[mr kazoodle]

Hi, I'm learning how to use multiple files for a single program, I made a successful example in which I called a member of a class in another cpp file. But when I tried to pass a parameter it stopped working and I don't have the slightest idea why. Can you help me?

*******************
main.cpp:
*******************
#include <iostream>
#include "out.h"

int main()
{   float var;
    std::cin >> var;
    out::out(var);
    return 0;}

*******************
out.h:
*******************
#ifndef OUT_H
#define OUT_H

class out
{   public:
        out(float);};

#endif // OUT_H

*******************
out.cpp:
*******************
#include <iostream>
#include "out.h"

out::out(float var)
{   std::cout << var;}

ERRORS:
In function 'int main()':
line 7 error: conflicting declaration 'out var'
line 5 error: 'var' has a previous declaration as 'float var'

You need to instanciate your class like this:

out myInstance(var);
