Answer 2

#include<stdio.h>
int sum1(int arr[][4],int hang,int lie)
{
int i = 0,j = 0,sum = 0;
for(i=0;i<hang;i++)
{
for(j=0;j<lie;j++)
{
sum += arr[i][j];
}
}
return sum;
}
int sum2(int (*p)[4],int hang,int lie)
{
int i = 0,j = 0,sum = 0;
for(i=0;i<hang;i++)
{
for(j=0;j<lie;j++)
{
sum += p[i][j];
}
}
return sum;
}
void main()
{
int arr[3][4] = {1,2,3,4,5,6,7,8,9,10,11,12};
int s1 = sum1(arr,3,4);
int s2 = sum2(arr,3,4);
printf("sum1 = %d,sum2 = %d\n",s1,s2);
}
