How to parse a string to an int in C++?
I have done some research and some people say to use atio and others say it's bad, and I can't get it to work anyways.
So I just want to ask flat out, whats the right way to convert a string to a int.
string s = "10";
int i = s....?
Thanks!
Some handy quick functions (if you're not using Boost):
template<typename T>
std::string ToString(const T& v)
{
std::ostringstream ss;
ss << v;
return ss.str();
}
template<typename T>
T FromString(const std::string& str)
{
std::istringstream ss(str);
T ret;
ss >> ret;
return ret;
}
Example:
int i = FromString<int>(s);
std::string str = ToString(i);
Works for any streamable types (floats etc). You'll need to #include <sstream> and possibly also #include <string>.
