Re: compilation error with overloaded output operator

The following program is ONLY for learning C++.

Consider the program x.cpp:

#include <cstdlib>
#include <iostream>

using namespace std;

template <typename Type>
inline ostream& operator<<(ostream& os, Type obj)
{
        Type temp;
        temp = obj;

        return os;
}

int main()
{
        int x = 100;
        cout << x;
        cout << endl;
        cout << 10;
        cout << endl;
        cout << "Enter some integers: ";
        cout << endl;

        return EXIT_SUCCESS;
}

When I compile this program as
g++ -std=c++98 -pedantic -Wall -Wextra x.cpp

I get compilation error for the line
        cout << "Enter some integers: ";

Here are the actual compilation errors:

x.cpp: In function `int main()':
x.cpp:22: error: ambiguous overload for 'operator<<' in 'std::cout <<

_CharT*) [with _CharT = char, _Traits = std::char_traits<char>]

Question:
The ambiguity error is reported by g++ for the line
        cout << "Enter some integers: ";
because this program has the function defined for the overloaded
operator<<() and the standard library also
defines it - multiple functions for operator<<() and hence the error.

But what I do not understand is that why similar ambiguity error is
not reported for the lines
        cout << x;
        cout << endl;
        cout << 10;

Kindly explain.
