Using char as a return type
Hey guys,
I am writing a C++ console app that carries on a conversation with the user. I need to be able to easily write functions that might take the user's input (type char), then make some decision about what to say, then finally return a value of type char. I would like to do it something like this... (leaving out irrelevant code)
Code:
char someFunction()
{
char output;
...
... // Decide what to say
...
return output;
}
int main()
{
cout << someFunction() << endl;
return 0;
}
I can get it to compile without any errors, but I don't get the right output, I get goofy control characters. You can put a function inside a cout statement as long as the function return a char, right?
Just in case that's wrong, I also tried to get around that by doing this...
Code:
int main()
{
char word;
strcpy(word, someFunction());
cout << word << endl;
return 0;
}
Didn't work either. I could just put the cout statement inside the function, but that defeats the whole purpose of using encapsulation. I need to be able to write many small functions that return char because I will probably change this to a GUI later and the cout statements become useless.
Why is it showing control characters? What am I doing wrong?
