PASSING 2-D ARRAY TO A FUNCTION

There are three ways in which we can pass a 2-D array to a function.these are illustrated in the following program.

main()
{
int a[3][4]={1,2,3,4,5,6,7,8,9,8,7,6};
clrscr();
display(a,3,4);
show(a,3,4);
print(a,3,4);
}



display(int *q,int row,int col)
{
int i,j;
for(i=0;i<row;i++)
{
for(j=0;j<col;j++)
printf("%d",*(q+i*col+j));
printf("\n");
}
printf("\n");
}
show(int (*q)[4],int row,int col)
{
int i,j;
int *p;
for(i=0;i<row;i++)
{
p=q+i;
for(j=0;j<col;j++)
printf("%d",*(p+j));
printf("\n");
}
printf("\n");
}
print(int q[][4],int row,int col)
{
int i,j;
for(i=0;i<row;i++)
{
for(i=0;i<col;j++)
printf("%d",q[i][j]);
printf("\n");
}
printf("\n");
}

OUTPUT:
1   2   3   4
5   6   7   8
9   8   7   6

 1   2   3   4
5   6   7   8
9   8   7   6

1   2   3   4
5   6   7   8
9   8   7   6
