There's nothing to do with the type of "A String". The reason for which the first code gives compilation error is: operator (<<) has higher precedence than ternary operator (?:) so, without braces your are actually messing up the parsing of "cout << << << "stream.
* cout << test ? "A String" : 0 << endl; * consider removing the last "*<<endl*". It shall give no compilation error. * cout << test ? "A String" : 0;* // this compiles and runs fine with my compiler(g++ 4.5), but as *cout << test* will take precedence, there is no point of putting a ternary operator there, unless you use braces, of course. In teh second case however, reason given is valid: i.e. return type of ternary operator is determined by "A String" and the expression 0 will be taken as address of a string location. Hence, there is no guarantee of output.
