void computeKilosPerHour (float kilos, float hours, float average)
{
    int main ()
    {
        // statements
    }
    // statements
}

The compiler does not like about the attempt to define a function inside definition of a function.

Compiler does not complain about your another function (printD..), does it?

Don't try and define a function inside another function.
