I have tried every thing which i could but this code is giving me errors. Both syntax are not working. I have commented operator[] but please provide a solution for that as well.
#include <bits/stdc++.h>
using namespace std;
int main() {
typedef vector< tuple<int, int, int> > my_tuple;
my_tuple tl;
tl.push_back( tuple<int, int, int>(21,20,19) );
for (my_tuple::const_iterator i = tl.begin(); i != tl.end(); ++i) {
//cout << get<0>(tl[i]);
//cout << get<0>(tl[i]);
//cout << get<0>(tl[i]);
cout << get<0>(tl.at(i));
cout << get<1>(tl.at(i));
cout << get<2>(tl.at(i));
}
return 0;
}
while printing tuple in for loop i am getting error.
error: no matching function for call to 'std::vector<std::tuple<int, int, int> >::at(std::vector<std::tuple<int, int, int> >::const_iterator&)'
and for operator[ ]
error: no match for 'operator[]' (operand types are 'my_tuple {aka std::vector<std::tuple<int, int, int> >}' and 'std::vector<std::tuple<int, int, int> >::const_iterator {aka __gnu_cxx::__normal_iterator<const std::tuple<int, int, int>*, std::vector<std::tuple<int, int, int> > >}')
#include <bits/stdc++.h>
using namespace std;
int main() {
typedef vector< tuple<int, int, int> > my_tuple;
my_tuple tl;
tl.push_back( tuple<int, int, int>(21,20,19) );
for (my_tuple::const_iterator i = tl.begin(); i != tl.end(); ++i) {
cout << get<0>(*i) << endl;
cout << get<1>(*i) << endl;
cout << get<2>(*i) << endl;
}
cout << get<0>(tl[0]) << endl;
cout << get<1>(tl[0]) << endl;
cout << get<2>(tl[0]) << endl;
return 0;
}
Your i
is an iterator, which is sort of like a pointer, so you need to dereference it, not pass it to operator []
or at()
:
get<0>(*i);
