char + int => int / Problem with cout

[Tr1ckSilv3r]

Hey Guys,

I'm pretty new to C++. Earlyer did a bit python so I'm not that precise as I should be in cpp I guess.

Following code always gives me the Output you see on the bottom.
I

Hero::Hero(string hname, int health, int mana, int atk, int def){
	hname_ = hname;
	health_ = health;
	mana_ = mana;
	atk_ = atk;
	def_ = def;

}

void Hero::heal(int amounth){
	health_ += amounth;
	if (health_ >= 100){
		health_ =100;
	}
	cout << hname_ + " was healed by " + (char)amounth + " and his health is now " + (char)health_ << endl;

}

cout << hname_ + " was healed by " + (char)amounth + " and his health is now " + (char)health_ << endl;

Dieter was healed by  and his health is now d

I'm trying to add chars to ints by assigning them as char variables for the cout. If i put them ints again it returns an error message.

I already looked around a little and normally an int + char should remain an int, shouldn't it?

Tipps please. :)

Why not change them to int across the board?

because you are trying to concatenate strings "+"

try this instead
cout << hname_ << " was healed by " << amounth << " and his health is now " << health_ << endl;

derp yea, Jay is right

You can't add an int to a string, that's why you get the error message without casting to char.

But when you cast to char, you're converting the heath improvement (presumably between 0 and 100), into a single ASCII character. For example, if you add 32 to health, then (char)amounth is a space.

You need to output the different types separately:
cout << hname_ << " was healed by " << amounth << " and his new health is now " << health_ << endl;
Note that this also more efficient because you aren't creating a bunch of temporary strings.

Argh!!!

You are so right. Too much python during the last weeks.

Thank you very much.

Don't forget to mark as solved!

Have fun programming
