i'm trying to work with 2D array in C but i'm getting an error "size of type unknown or zero"what should i do?

Answer 1

use pointer
int **arrayptr
arrayptr = (int**)x*malloc(sizeof(int*));
for(i=0;i arrayptr[i]=(int*)y*malloc(sizeof(int));

Answer 2

make sure you put the size of your array... for example
int x = 2;
int y = 3;
int number[ x ][ y ];

// x stands for row size
// y stands for column size

Answer 3

u have to define the size of the column and line

Answer 4

in declaration section write such as

int row=31, colon=34;
int arrayname[row][colon];
