c++ - Initialize multidimensional array with zeros

In C++ you can initialize a one dimensional array with 0 with a code like this:

int myarray[100] = {0};

Is there a similar way for multidimensional arrays? Or am i forced to initialize it manually with for loops?

See Question&Answers more detail:os

You do it exactly the same way

int marr[10][10] = {0};

Edit:

This is a C solution. For a C++ solution you can go for:

int marr[10][10] = {};

These 2 solutions do not work for arrays that have size defined via variables. e.g.:

int i, j = 10;
int marr[i][j];

To initialize such an array in C++ use std::fill.
