(stackoverflow.com/questions/10898007/…) So some low-level operations might be a bit more complex, like writing to a file or stream, or setting all the memory cells to a particular value. | |

| Sep 30, 2018 at 0:23 | comment | added | Dronz | @LeviMorrison Oh! That actually makes intuitive sense to me in this case, thanks! (I was thinking it was related to how many modern graphics coordinates use X and Y.) | |
| Sep 29, 2018 at 19:20 | comment | added | Levi Morrison | @Dronz It's because that's the C++ memory model -- the columns are contiguous in memory, not the rows. In Fortran it's the other way. | |
| May 15, 2018 at 3:29 | comment | added | Dronz | What I don't understand is why so many people think of the first index as the rows, and the second as the columns. Rebellion against XY coordinate diagrams in math class? | |
| Mar 21, 2018 at 18:51 | comment | added | Zar Shardan | @katta most nontrivial C++ programs do use STL anyway, so this is a good solution, just not for some minor number of cases including yours. | |
| Apr 19, 2017 at 16:01 | comment | added | katta | This is not a good solution if I don't want to load STL because of memory constrains. | |
