Error: no match for 'operator>>' (operand types are 'std::istream {aka std::basic_istream<char>}' and 'std::vector<double>')

Question

this is my first StackOverflow.

When I run my code I get this error:

error: no match for 'operator>>' (operand types are 'std::istream {aka 
std::basic_istream<char>}' and 'std::vector<double>')

The error is in line 9 but I don't know why.

This is my code:

1 #include <vector>
2 #include <iostream>
3 using namespace std;
4
5 int main() {
6
7    vector<double> numbers[10];
8    for (int i=0;i<10;i++) {
9        cin >> numbers[i];
10    }
11 }

This numbers are for the lines, they are not actually in the code.

Basically, what I want to create is program that will ask me for 10 numbers.

Oh, I nearly forgot! I use Code::Blocks, version 17.12.

Thanks for the help.

Answer 1

You've already gotten an answer to the question you asked, but I'd suggest going a step further: eliminate the for loop and don't bother specifying the size of the vector either:

vector<double> numbers;

copy_n(istream_iterator<double>(cin), 10, back_inserter(numbers));

Oh, and one other detail--you probably want to break (or never form) the habit of using namespace std; --it can lead to problems.
