Max not displayed when code executed

Question

Here I have written a code that finds the maximum number out of three integers using user defined Function, but the problem is that when I execute it, it doesn't display the maximum number. Can someone help me out? Please and thank you.

#include <iostream>
int max(int n1, int n2, int n3);

using namespace std;
int main()
{
int n1,n2,n3,i=1;
while (i>0)
{
cout<<"enter first number:"<<endl;
cin>>n1;
cout<<"enter second number:"<<endl;
cin>>n2;
cout<<"enter third number:"<<endl;
cin>>n3;
max( n1, n2, n3);
cout<<endl;
cout<<"do you want to enter three integer numbers again (press a negative value to exit)"<<endl;
cin>>i;
}
return 0;
}

int max(int n1, int n2, int n3)
{
int max;
if (n1>n2 && n1>n3)
max=n1;
else if (n2>n1 && n2>n3)
max=n2;
else
max=n3;
return max;
}

Answer 1

you should share the code itself,not copy all its contents in a question

Answer 2

Ohkay and how do I do that? Like how do I upload the file.
(New here, so still figuring out stuff.)

Answer 3

Where else can I paste my code? :/
