Consider the following C++ code:
class A
{
int do(string key, bool b) { cout << "do('" << key << "', " << (b ? "true" : "false") << ")" << endl; };
int do(string key, string value) { cout << "do('" << key << "', '" << value << "')" << endl; };
};
...
A *a = new A();
a->do(”do”, “something”);
What is printed? Well, not what I expected:
# ./reason1
do('do', true)
Intuitively, the second method, do(string string), should be executed, but gcc (4.1) executes the first method, do(string, bool). This is because the second ’string’, “something”, is interpreted as ‘char *’.
One down, 1000 more reasons to come.
