Boost:LexicalCast

Example

Strings to numbers conversion

The following example treats command line arguments as a sequence of numeric data

#include <boost/lexical_cast.hpp>
#include <vector>

int main(int /*argc*/, char * argv[])
{
    using boost::lexical_cast;
    using boost::bad_lexical_cast;

    std::vector<short> args;

    while (*++argv)
    {
        try
        {
            args.push_back(lexical_cast<short>(*argv));
        }
        catch(const bad_lexical_cast &)
        {
            args.push_back(0);
        }
    }

    // ...
}
