Dev C++ cant accept vector??

Hi, im using vector strvector. it works in unix but when i run in Dev c++, it prompt me error like no matching function for call tp `Vector`.....etcc why is this so??

1. Show your code. 2. Show the exact error message that the compiler issued.

#include <vector>
using namespace std;

vector<string> vectorstr ;

....

vectorstr.push_back("....")

...

for(int i=0;i<this->vectorstr.size(); i++){
cout << "test:" << this->vectorstr.at(i) << endl;
}

...

void removeduplicates(vector<string>& vec){
sort(vec.begin(), vec.end());
vec.erase(unique(vec.begin(), vec.end()), vec.end());
}

i have been getting error like: implicit declaration of function int sort implicit declaration of function int unique no matching function for call to vectormodified on Sunday, November 29, 2009 12:55 PM

That doesn't help, does that? Which headers are you including? I suspect that you're missing something. Most probably #include <string> Uncheck the "Encode HTML tags when pasting", paste your code into the window, and ensure your code snippet is within a pre block (selecting the "Code Block" option, which you've already done).

i have these headers

#include <iostream>
#include <sstream>
#include <fstream>
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <time.h>
#include <ctype.h>
#include <map>
#include <vector>
using namespace std;

I think you should #include<algorithm> to use sort.

Hi sarath, tks. i included #include <algorithm> and the error message on sort is no more. however, the error on "no matching function for call to `vector...." is still there. im pretty sure i use the vector correctly. the error is at the line: cout << this->vector.at(i) << endl;

Could you please post the full and exact error message ?

The following piece of code (basically yours...) runs fine on my system (WinXP, Visual Studio 2005):

#include <string>
#include <vector>
#include <iostream>
using namespace std;
void main()
{

vector<string> vectorstr;
vectorstr.push_back("....");

for(int i=0;i<vectorstr.size(); i++)
{
cout << "test:" << vectorstr.at(i) << endl;
}

}

I think the char* is not automatically deduced from the string class. Please try the following code. cout << this->vector.at(i).c_str() << endl;

You keep giving showing your code in bits and pieces. It's very difficult to help you. However, it appears that you're trying to sort a vector such that there are only unique elements. See if this helps:

// Cons.cpp : Defines the entry point for the console application.

#include "stdafx.h"
#include <iostream>
#include <vector>
#include <string>
#include <algorithm>

using namespace std;

void UniqueSort(std::vector& MyVec)
{
sort(MyVec.begin(), MyVec.end());
MyVec.erase(unique(MyVec.begin(), MyVec.end()), MyVec.end());
}

int _tmain()
{
vector vec;
vec.push_back("one");
vec.push_back("two");
vec.push_back("one"); //duplicate
vec.push_back("four");
vec.push_back("five");
vec.push_back("six");
vec.push_back("seven");
vec.push_back("eight");
vec.push_back("six"); //duplicate

//cout<<"Before sorting"<
