Initialising a 2D numeric array
What is the format to initialise a 2D array(numeric) in Turbo C++ and Xcode(Command Line Tool --> C++) ?
My doubt arises because, the PC in my school which runs the Turbo C++ environment, the syntax is --
int array[rows][colms];
but SOMETIMES whilst working on my Mac at home (Xcode), the program only works when the syntax is --
int array[colms][rows];
Please help!
On a side note, is a Turbo C++ like software available for Mac or is Xcode fine ?

C and C++ do use row-major convention. Therefore:
[code]int array[ROWS][COLS];
See http://www.cplusplus.com/doc/tutorial/arrays/#multidimensional_arrays
The result should be same with all compliant compilers and IDE's.
However, that is a declaration, not initialization. Initialization sets the values of the array too.

@keskiverto -
Sorry for the mistake in terms. I do that often even though i know the difference xP
And as a rule both school and home IDE's follow the Row Major convention. But only in few programs the compiler(Xcode) seems to function on a column major form, i.e. only then do I get the desired output.
Of course, it may also be a logical error on my part and i'll recheck the code for any mistakes although I'm pretty sure there is no error. If the problem still persists i'll paste the code-desired output- and actual output here!!
Until then, Thank You so much for the help !
