vectors scope

[adam2016]

Hi guys I was expecting an out of scope error in my program but it worked fine with no errors I'm just wondering why this happens as I declared the items of myVector inside the main function yet I can still access them in a function outside the main function

  #include <iostream>
#include <vector>

using namespace std;

void printVector();

 vector<int> myVector;

int main()
{
    myVector.push_back(1);
    myVector.push_back(23);
    myVector.push_back(20);
    myVector.push_back(17);
    printVector();
}

void printVector(){

     for(unsigned int i = 0; i<myVector.size();i++){

           cout << myVector.at(i) << endl;
     }
}

vector<int> myVector;

int main()
{
...

Nope, you put it outside main so it exists everywhere.

yup but would that mean that all of myVectors elements can be accessed and declared anywhere also?

if it's not declared inside a function/class/struct... it's a global so can be seen everywhere. Where you set/get values does not change where it's visible from as that is the visibility.

some of this may help?
