1) Splain how each of the following work:
1a) printf("Test score %d: %d\n", aa,scores[aa]);

ANSWER: print decimal value of variables aa and scores[aa]

1b) char fname[7]={'A','l','i','s','o','n','\0'};

ANSWER: declare and initialize character array fname
        with 7 elements, assigning a letter to each elment
        except the last, which is assigned NULL

1c) printf("\nYour name is '%s' \n", fname);
 
ANSWER: print all elements of arraya fname as a string

1d) 
int main(void)
{
  int ii; // declare int 
  char fname[10]; // declare character array with 10 elements
  printf("Enter your first name: "); // prompt for input 
  scanf("%s", fname); // read stdin as a string,
                      // assign values to elements of array fname
                      // add NULL at the end
  printf("\nYour first name is "); // print output descriptin
  for(ii=0; fname[ii] != '\0'; ii++) // initialize ii to 0
                                     // if iith element is not NULL, do block
                                     // increment ii, and repeat  
  {
    printf("%c", fname[ii]); // print char value of iith element of array
  }
  printf("\n"); // print newline
 
  return 0; // return 0 to calling program
}

2) What line declares and initializes an array named student that contains 
   data like the following:
  Natasha Mayfield Philosopy
  Kwakay  Shu      Physics
 
ANSWER: char name[2][3][20] // 2 records,3 elements/record ,20 char/element

3) What printf line would output the S in Shu in question 2?

ANSWER: printf("%c",name[1][1][0]); // 2nd record, 2nd element, first char

4) What printf line would output the string Physics?
 
ANSWER: printf('%s",name[1][2]); // string at 2nd record, 3rd element
