Hi All,
I have the following problem:
I read lines from DXF file ( AutoCAD format file ). Then I need to
remove white spaces from lines to continue working on data i.e.
converting from string to int and so on. My StripWhiteSpace function
works in test program:
Can't help you with your code but I can give you something else that
might be usedful, the following code can be used to convert strings to
a number of types (all the native builtin) even if there are spaces:
#include <iostream>
#include <sstream>
#include <string>
/*
* Converts a string to some other type. The type converted to must
* have a std::ostream& operator>>(std::ostream&, T) method declared.
* Works for all built-in types.
*/
template <class T>
T stoa(const std::string& s)
{
T t;
std::istringstream iss(s);
if (!(iss >> t))
throw std::string("Can't convert '") + s +
"' to '" + typeid(t).name() + "'\n";
return t;
}
int main()
{
std::string s = " -54 ";
try {
int d = stoa<int>(s);
} catch(std::string& s) {
std::cout << s;
}
return 0;
}
It's my own adoption of the code from the FAQ:
