함수의합을하는프로그램을짜는데
매개변수를써서작성하는데오류가 나네요
포인터와 매개변수 입출력에서 잘못한것 같은데...
힌트 부탁드려요

#includestdio.h

voidShowArr2DStyle(int(*arr)[3],intcolumn)
{
inti,j;
for(i=0;icolumn;i++)
{
for(j=0;j3;j++)
printf(%d,arr[i][j]);
printf(\n);
}
printf(\n);
}

intSum(int(*arr1)[3],int(*arr2)[3],intcolumn)
{
inti,j,sum=0;
for(i=0;icolumn;i++)
for(j=0;j3;j++)
sum[i][j]=arr1[i][j]+arr2[i][j];
returnsum;
}

intmain(void)
{
intarr1[3][3]={1,2,3,4,5,6,7,8,9};
intarr2[3][3]={9,8,7,6,5,4,3,2,1};
intarr3[3][3]={0};
ShowArr2DStyle(arr2,sizeof(arr1)/sizeof(arr1[0]));
ShowArr2DStyle(arr2,sizeof(arr2)/sizeof(arr2[0]));
printf(arr의합:%d\n,Sum(&arr1,&arr2,sizeof(arr1)/sizeof(arr1[0])));
printf(arr3%d\n,arr3);
return0;
}
