return char1 + char2? Isn't it possible?
- by pocoa
I'm trying to return a string from a function. Which basically adds some chars together and return the string representation.
string toString() {
char c1, c2, c3;
// some code here
return c1 + c2; // Error: invalid conversion from `char' to `const char*'
}
it is possible to return boolean values like return c1 == 'x'. Isn't it possible to return string values? I know that it is possible to it like this:
string result;
result.append(c1, c2);
return result;
I'm new to C++ so I thought that there must be more elegant solution around.
