Converting string to bool
-
Thanks for the reply. This can be done. But instead I am looking for some function that does this like atoi() or itoa() for string to int and vice versa. Is there any function for strings to bool.
please reply to this question[^] first before we can reply to you efficiently

you misunderstood me. I meant what is contained within that string ? 1/0 ? true/false ? checked/unchecked ? white/black ?

true/false :) (well, that what he said in his post)

what about
bool f = temp == "true";

Why ? That's quite simple, why do you want to use an existing function for that ?

Not as far as I know.

Good news: it exists, is
atob. The bad news is that you have to code it (anyway you got so many hints about). :-DIf the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler. -- Alfonso the Wise, 13th Century King of Castile.

I am getting a string from map that can be either true or false. Is there any function or some alternative to convert this string into bool. So that I can store it in a bool variable.
string temp;
temp=MyMap.find("Check")->second; // give either true or falseI want to convert temp to bool. THANKS.
bool bVal = (temp == "true"?true:false);

why do you need the ?: operator ? the std::string::operator==() already returns a bool. in the same direction, why wouldn't you write this then :
bool bVal = ((temp == "true") == true ? true : false)
or
bool bVal = (((temp == "true") == true) == true ? true : false)
or just
bool bVal = (temp == "true")
