Defining structure variable after structure type

Question

#include 

struct people 
{
    int id;
} person; // that part

int main()
{
    person = {3};   
    std::cout << person.id;

    return 0;
}
         


        

Answer 1

You can't use the structure initialization syntax in a normal assignment, it has to be done when you declare your variable:

struct people 
{
    int id;
} person = { 3 };

If you have a C++11 compatible compiler, you can use the uniform initialization syntax to copy later though:

person = people { 3 };
