Question

the programming language that we used in this questions is C

Consider this declaration of a 3x5 2D array of doubles:
double m[3][5];
Assume the following:
sizeof (double) is 8 (bytes)
& (m[0][0]) is 2056 (address of element m[0][0] in decimal (not Hex.)
QUESTION: what is & (m[2][3]) (numerically)

You want to write a function foo that operates on a square NxN 2D array of integers (where N is a constant like 16 below).
Since this function will only be operating such 2D arrays, it only needs to have a single parameter - the 2D array (the function "knows" about the constant N).
Example code invoking such a function below.
QUESTION: Select the function "stub" (empty body) which is correct for this scenario
#define N 16
// the definition of function foo() would be here
int main(){
int a[N][N];
// blah blah blah
foo(a);
// blah blah blah
}
O void foo(int a[N][]) {
// body of func
}
O void foo(int a[][]) {
// body of func
}
O void foo(int a[N*N]) {
// body of func
}
O void foo(int a[][N]) {
// body of func
}
