Re: Dynamic memory

[Binarydepth via Digitalmars-d-learn]

Here is what I'm trying to do :

import std.stdio : readf, writef;
void main()     {
        int[2][] nam;
        int num;
        readf(" %d", &num);
        nam.length = num;
        foreach(nim; 0..num)    {
                readf(" %d %d", &nam[0][num], &nam[1][num]);
        }
        foreach(nim; 0..num)    {
                writef(" %d %d\n", &nam[0][num], &nam[1][num]);
        }
}
And here is the output I get when running the program :

I just want to read and print data depending on user input.
