Question

What will be the address of the arr[2][3] if arr is 2d?

Answer 1

Answer:

you can't tell the exact address as it may vary depending on how the memory has been allocated to it but in general, take reference the starting position i.e. arr[0][0] and keeps adding the size of int.

Explanation:

#include <stdio.h>

int main()

{

int arr[3][3];

for(int i=0;i<3;i++){

for(int j=0;j<3;j++)

printf("%d %d %d\n",&arr[i][j],i,j);

}

return 0;

}

returns

1732977680 0 0

1732977684 0 1

1732977688 0 2

1732977692 1 0

1732977696 1 1

1732977700 1 2

1732977704 2 0

1732977708 2 1

1732977712 2 2

every address is incremented by 4 in this case.
