2D array initialization

#1

I am confused with the 2D array initialization.
What is the difference between
int a[10][10] and int a[ ][10]?
is a[10][] allowed?

Thanks!

hello @ryoojw94

…

int a[10][10] -> here we are declaring 10 x 10 matrix

int a[][10] -> here we are declaring matrix with atmost 10 columns and rows will be retermine by the data that u r using at the time of initilaisation.

in c++ this is not allowed.

one more thing , when we pass 2d array in any function then mentioning column number is mandatory
