I have a 2-dimensional array and I am passing it into a function to carry out certain operations. I'd like to know the correct way of doing it...
#define numRows 3
#define numCols 7
#define TotalNum (numRows*numCols)
int arr[numRows][numCols] = {{0,1,2,3,4,5,6}, {7,8,9,10,11,12,13},{14,15,16,17,18,19,20}};
void display(int **p)
{
printf("\n");
for (int i = 0; i< numRows;i++)
{
for ( int j = 0;j< numCols;j++)
{
printf("%i\t",p[i][j]);
}
printf("\n");
}
}
int main() {
display(arr);
}
I get an error message:
'display': cannot convert parameter1 from 'int' to 'int*'
Is this the correct way of passing a 2-dimensional array into a function? If not, what is the correct way?
