When i am coding the code below, i am getting a negative sum (-294967296).
#include<iostream>
#include<vector>
#include<numeric>
using namespace std;
int main() {
vector<long long int> v={1000000000 , 1000000000 , 1000000000 , 1000000000};
cout<<"Sum of all the elements are:"<<endl;
cout<<accumulate(v.begin(),v.end(),0);
}
but when i am coding the code below i am getting a positive sum (2000000000)
#include<iostream>
#include<vector>
#include<numeric>
using namespace std;
int main() {
vector<long long int> v={1000000000 , 1000000000};
cout<<"Sum of all the elements are:"<<endl;
cout<<accumulate(v.begin(),v.end(),0);
}
What might be the reason?
