int main() {

   StudentAttempt throwDist[] = {
      {50, "A"},      {22, "A"},      {16, "B"},      {44, "C"},
      {33, "D"},      {34, "E"},      {22, "F"},      {21, "G"},
      {49, "A"},      { 5, "B"},      { 2, "C"},      {22, "A"},
      {33, "B"},      {22, "C"},      {22, "D"},      {44, "E"},
   };
   int len = sizeof( throwDist )/ sizeof( throwDist[0] );

Answer : Help me understand sizeof()

I believe the the first one returns the size of the array (number of elements) and the second one returns the size of one element in the array.
