vector iterator c++ code example
Example 1: c++ vector iterator
#include <iostream>
#include <vector>
using namespace std;
vector<int> myvector;
for (vector<int>::iterator it = myvector.begin();
it != myvector.end();
++it)
cout << ' ' << *it;
cout << '\n';
Example 2: c++ vector iterator
vector<string> vData;
vData.push_back("zeroth");
vData.push_back("first");
vData.push_back("second");
vData.push_back("third");
std::vector<string>::iterator itData;
for (itData = vData.begin(); itData != vData.end() ; itData++)
{
auto ElementIndex = itData-vData.begin();
auto ElementValue = vData[ElementIndex];
cout << "[ElementIndex:" << ElementIndex << "][ElementValue:" << ElementValue << "]\n";
}
Example 3: iterate on vector c++
#include <iostream>
#include <vector>
int main ()
{
std::vector<int> myvector;
for (int i=1; i<=5; i++) myvector.push_back(i);
std::cout << "myvector contains:";
for (std::vector<int>::iterator it = myvector.begin() ; it != myvector.end(); ++it)
std::cout << ' ' << *it;
std::cout << '\n';
return 0;
}
Example 4: declaring iterator in cpp
vector<int>::iterator ptr;
