warning with function templates

[Christian Christmann]

Hi,

when I run this code:

#include <iostream>
using namespace std;

template <class T>
T GetValue(int a)
{
    if (a = 1)
        return 1;
    else
        return 2.55; // line 11
}

int main()
{
    int a = GetValue<int>(1); // line 16
    cout << "\nInt a : " << a << endl;

    double b = GetValue<double>(2);
    cout << "\nDouble b: " << b << endl;

    return 0;
}


I get the gcc warning:
temp.cpp: In function `T GetValue(int) [with T = int]':
temp.cpp:16:   instantiated from here
temp.cpp:11: warning: converting to `int' from `double'


Why? 
Line 16 should not be reached when the function is called
from line 11.

Is there any way to avoid this warning?

Thank you
Chris
