二维数组如何作为函数的参数传递

int main()
{
	int a[3][2] = {1,2,3,4,5,6};
	print1(a);
	return 0;
}

void print1(int **b)

void print1(int b[3][])

void print1(int (&b)[3][2])

void print2(int b[3][2])

void print3(int b[][2])

#include <stdio.h>
#include <stdlib.h>
void print1(int (&b)[3][2], int row, int col)
{
	printf("Run print1\n");
	for (int i = 0; i < row; i++)
		for (int j = 0; j < col; j++)
			printf("%d\n", b[i][j]);
}
void print2(int b[3][2], int row, int col)
{
	printf("\nRun print2\n");
	for (int i = 0; i < row; i++)
		for (int j = 0; j < col; j++)
			printf("%d\n", b[i][j]);
}
void print3(int b[][2], int row, int col)
{
	printf("\nRun print3\n");
	for (int i = 0; i < row; i++)
		for (int j = 0; j < col; j++)
			printf("%d\n", b[i][j]);
}

int main()
{
	int a[3][2] = {1,2,3,4,5,6};
	print1(a, 3, 2);
	print2(a, 3, 2);
	print3(a, 3, 2);
	system("pause");
	return 0;
}
