c++ - typedef and multi-dimensional array -

- 



    #include <iostream>     using namespace std;      typedef int array[2];      int sum(array a[], int n)     {         int sum = 0;          for(int = 0; < 2; i++)            for(int j = 0; j < n; j++)               sum += a[i][j];          return sum;     }      int main()     {         int n = 2, sum;         array a[n];          for(int = 0; < 2; i++)            for(int j = 0; j < n; j++)                a[i][j] = * n + j;          cout << sum(a, n) << endl;          return 0;     }

it use typedef in global scope? use typedef declare multi-dimensional array, instead of a[][]?

i have many .npy (numpy) , .json files saved in s3, need download , load these files. for json files downloading files , loading dictionary using following code: obj = s3.object(bucket, key) response = obj.get() body = response['body'].read().decode('utf-8') data = json.loads(body) that way avoid writing .json file disk , reading it. now want same .npy files, equivalent? currently downloading file, saving temp file on disk , loading np.load avoid if possible. following https://stackoverflow.com/a/28196540/3509999 : obj = s3.object(bucket, key) io.bytesio(obj.get()["body"].read()) f: # rewind file f.seek(0) arr = np.load(f) wiki
