return string; not working without curly brackets

Question

This is the function I have in a .h file:

static std::string ReturnString(std::string some_string)
    return ("\t<" + some_string + " ");

The compiler (g++ -std=c++0x -pedantic -Wall -Wextra) throws these errors:

error:expected identifier before '(' token
error:named return values are no longer supported
error:expected '{' at end of input
warning: no return statement in function returning non-void [-Wreturn-type]

But,

static std::string ReturnString(std::string some_string)
{
    return ("\t<" + some_string + " ");
}

works fine. Even,

static std::string ReturnString(std::string some_string)
{
    return "\t<" + some_string + " ";
}

works too.

Could someone please explain this to me please? Am I missing some basic knowledge of strings?

Thanks.

Answer 1

static std::string ReturnString(std::string some_string)
    return ("\t<" + some_string + " ");

It's actually a basic knowledge of C++ that you're missing. In C++, function bodies must be enclosed in curly braces, {}. So, the correct definition for the function above would be:

static std::string ReturnString(std::string some_string)
{
    return ("\t<" + some_string + " ");
}
