interating a vector c++ code example
Example 1: 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 2: c++ looping through a vector
vector<int> vi;
...
for(int i : vi)
cout << "i = " << i << endl;
