How to draw 2D Array?

Question

I've tried this, but have error

#include <stdio.h>
#include <stdlib.h>

void Draw_2D_Array(int raws, int cols, int *Arr)
{
int i,j;
for (i = 0; i < raws; i++)
{
for (j = 0; j < cols; j++)
{
printf("%d ", Arr[i][j]);
}
printf("\n");
}
return 0;
}
int main()
{
int a[3][3]={1,2,3,4,5,6,7,8,9};
Draw_2D_Array(3,3,a[3][3]);
return 0;
}

Answer 1

Try it like this;

#include <stdio.h>

void Draw_2D_Array(int rows, int cols, int Arr[rows][cols])
{
int i,j;
for (i = 0; i < rows; i++)
{
for (j = 0; j < cols; j++)
{
printf("%d ", Arr[i][j]);
}
printf("\n");
}
return;
// void function doesn't return
// int, just use return.
}

int main()
{
// Initialize your array clearly
int a[3][3]={{1,2,3},{4,5,6},{7,8,9}};
Draw_2D_Array(3,3,a);
return 0;
}
