vector does not name a type

[Winsu]

I don't why, but it doesn't recognize neither vector nor string....I think I must have some wrong configuration in my settings project, but I don't what it can be...does any one can help me?

#include <stdio.h>
#include <string>
#include <tuple>
#include <iostream>
#include <vector>


struct Assoc{
	vector<pair<string,int>> vec;
	
	const int& operator[] (const string&) const;
	int& operator[](const string&);
};



int main(){
	
}

Add on line 8:

using std::vector;
using std::string;
using std::pair;

[Winsu]

that's true they belong to the standard library...I guess I could insert too

using namespace std;

There is a rationale, why the language supports namespaces. I do suggest that you read first: http://www.gotw.ca/publications/migrating_to_namespaces.htm

Thanks, as my file was a simple .cpp I could use using directive but with more files, headers files and source files declare namespace explicitly in headers and use using directive in source files....thanks
