C ++ - multidimensional arrays

Question

When working with multidimensional arrays, is it possible to assign two different types of variables to an array ...

For example, if you have an array int example[i][j], is it possible for iand to jbe two completely different types of variables, such as int and string?

Answer 1

It looks like you are looking for:

std::vector<std::map<std::string, int> > myData1;

or perhaps:

std::map<int, std::map<std::string, int> > myData2;

First you need to resize the vector to the appropriate size before using the indexing operators:

myData1.resize(100);
myData1[25]["hello"] = 7;

... and the second will allow you to assign any element directly (and rarely):

myData2[25]["hello"] = 7;

Answer 2

No. It's impossible. You might want to learn the STL scheme .

Answer 3

, ++ integer (ex: int, long, unsigned int, size_t, char).
