Thread: C - function declearation

Hi Guys,

I have written the program for accesssing elements of 2D array using pointer to array of int which is as below:

void display(int (*)[4], int , int);

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

display(a, 2, 4); // this line is giving error

getch();
}

void display(int (*ptr)[4], int row, int col)
{

int i, j;
int *p;

for(i = 0; i < row; i++)
{
p = ptr + i;
for( j= 0; j < col; j++)
{
printf("%d ", *(p+j));
}
printf("\n");
}
}

But the function declearion line is giving the error and also I am not sure about function prototype written correct or not.

Please help me in how the function prototype and declearation has to be written for the above fucntion defination.

Thanks
