Error “xxxx”does not name a type

Question

I encountered a problem when tried compiling the following code:

#include 
#include 
#include 
#include 

        

Answer 1

You cannot execute arbitrary expressions at global scope, so

mapDial['A'] = 2;

is illegal. If you have C++11, you can do

map mapDial {
    { 'A', 2 }
};

But if you don't, you'll have to call an initialisation function from main to set it up the way you want it. You can also look into the constructor of map that takes an iterator, and use that with an array in a function to initialise the map, e.g.

map initMap() {
    static std::pair data[] = {
        std::pair('A', 2)
    };

    return map(data, data + sizeof(data) / sizeof(*data));
}

map mapDial = initMap();
