I've been playing around with this a little bit this evening and can't
get it to work correctly. This is my code so far (I've put it up on
ideone.com because it wraps in a nasty way when posted here directly):

Unfortunately it throws an out of range exception. This is the actual error:
 
unknown location(0): fatal error in "SCGITest": std::out_of_range:
vector::_M_range_check: __n (which is 49) >= this->size() (which is 15)
 
and I'm stumped. I'm also pretty sure my code is incorrect but haven't
found the right method to parse a std::vector<char> for the correct
values yet.
 
Anyone got any suggestions? Using iterators and containers seem to be a
bit of a pain at the moment. As far as I can tell this should be fine
since I'm using an iterator which should stop at the end of the vector
but it seems that is not the case.

Doh forgot to add this is my code for initialising the vector:
 
const char *c_netstring = "13:SCGI\01\0,Test";
const int string_length = 15;
std::vector<char> netstring {};
 
for(int i = 0; i < string_length; ++i)
{
netstring.push_back(c_netstring[i]);
}

Hi, i have a problem with my priority queue i am trying to create a priority queue of a class called duty with three elements but it produces an error. the sentence is :
 
the .h file is
///////////////////////////////////////////////////////////////////////////
#ifndef DUTY_H
#define DUTY_H
 
 
class duty
{
public:
duty();
virtual ~duty();
 
double costo_reducido;
double costo_real;
unsigned id;
bool operator ==( const duty &d2) ;
bool operator <( const duty &d2) ;
bool operator >( const duty &d2) ;
};
