My function looks like this:
string toOriginal(char c)
{
if (c == '$')
return "car";
else if (c == '#')
return "cdr";
else if (c == '@')
return "cons";
else
{
string t = to_string(c);
return t;
}
}
However, when my character c contains a value like 'r', I would like for it to return "r" as a string. However, it returns a string "114".
std::to_string does not have an overload that takes a char. It converts the char to an int and gives you the string representation of the int.
Use std::string's constructor.
string t(1, c);
You can also use alternative string constructor like this:
...
else
{
return std::string(&c, 1);
}
The method to_string() is for converting a numerical value to a string. A char is a numerical type.
