Question

I want to copy 2d array and assign it to another.

In python i will do something like this

grid = [['a','b','c'],['d','e','f'],['g','h','i']]
grid_copy = grid

I want to do same in C.

char grid[3][3] = {{'a','b','c'},{'d','e','f'},{'g','h','i'}};

How do i copy this array to copy_grid ?

Answer 1

Use memcpy , don’t forget to include <string.h>

#include <string.h>
void *memcpy(void *dest, const void *src, size_t n);

Or, do it manually using loop put each value one by one.
