modular and flexible programming

I am trying to learn how to make a modular program. So what I want to do is read an array of integers. Main:

#include <stdio.h>
#include <stdlib.h>
#define NMAX 10


void read (int *n, int a[NMAX]);

int main()
{
    int n, a[NMAX];
    read(&n,a);
    return 0;

}

Then I saved this file 'read.cpp':

#include <stdio.h>
#include <stdlib.h>
#define NMAX 10

void read (int *n, int a[NMAX])
{
    int i;
    printf("dati n:\n");
    scanf("%d",n);
    for (i=1;i<=*n;i++)
    {
        printf("a[%d]= ",i);
        scanf("%d\n",&a[i]);
    }

}

read.cpp compiles succesfully, but when I compile the main function I get the error "no reference to read".

Include read.cpp when compiling.

g++ -o out main.cpp read.cpp

or

add #include "read.cpp" in main program
