Can I initialize an STL vector with 10 of the same integer in an initializer list?

Question

Can I initialize an STL vector with 10 of the same integer in an initializer list? My attempts so far have failed me.

Answer 1

Use the appropriate constructor, which takes a size and a default value.

int number_of_elements = 10; int default_value = 1; std::vector<int> vec(number_of_elements, default_value); 

Answer 2

I think you mean this:

struct test {
   std::vector<int> v;
   test(int value) : v( 100, value ) {}
};
