This is for instance the case if.. - The matrix is very large and sparse (if any of the rows do not even need to be allocated but can be handled using a nullptr) or if - The rows do not have the same number of columns (that is if you don't have a matrix at all but another two dimensional construct) My Conclusion: Multidimensional array is not always bad because some cases it may make more sense and can be helpfull to programmer rather than make multidimensional array in one dimensional array. but still, one dimensional array is more faster and consume less memory rather than multidimensional array Well thats all about, thanks for your time and i'll see you later */
