 | Re: boost link error Not to sound counter-productive but there is an installer available for boost, if you're using Windows I would say it's definitely worth checking out. It takes a long time to download the files but, you get the pre-built .DLLs and .LIBs for multiple compilers, target platforms, and runtimes. After you …  |

 | What's up with all the "hacking" lately? I thought that's what we were doing, but we're not on the news.  |
| | I need to extract an integer value from the end of a string, and I'm a little bit lost on algorithm functions/classes in C#. Is there any sort of convenient class/function to help with this? Here is a sample string: "omaha nebraska weather 2400" |

| | string(size_t, char) is a constructor overload, the constructor is a function that initializes the class. Primitive data types (like int, float, double, char) don't have constructors, nor do they have functions associated with them.

| | If you're still wondering, a variable on the stack has an address, which points to a reserved section of memory. The process is veery similar to using dynamically allocated objects with pointers. Hopefully this small example can clear up some of it: [code] #include <iostream> using namespace std; int main() … |
