how to iterate trough a vector in c++ code example
Example 1: c++ iterate over vector
for(auto const& value: a) {
/* std::cout << value; ... */
}
Example 2: how to iterate trough a vector in c++
vector<int> myVector;
myVector.push_back(1);
myVector.push_back(2);
myVector.push_back(3);
myVector.push_back(4);
for(auto x: myVector){
cout<< x << " ";
}
vector<pair<int,int>> myVectorOfPairs;
myVectorOfPairs.push_back({1,2});
myVectorOfPairs.push_back({3,4});
myVectorOfPairs.push_back({5,6});
myVectorOfPairs.push_back({7,8});
for(auto x: myVectorOfPairs){
cout<< x.first << " " << x.second << endl;
}
Example 3: iterate on vector c++
// vector::begin/end
#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;
