   4.   ?    double fred[1000][80]

5. Given: double fred[20][50]; and given that sizeof(double) = 8, if the value of fred is 0x3000, at what memory address is fred[10][4] located?

   1.   ?    0x7032
   2.   ?    0x3000
   3.   ?    0x3FC0
   4.   ?    0x4032

6. Given the statement strcpy(s, "Bob"); what is the stored in cell s[3]?

   1.   ?    'B'
   2.   ?    'o'
   3.   ?    'b'

7. Arrays are passed to functions

   1.   ?    by value.
   2.   ?    be reference.
   3.   ?    by inference.
   4.   ?    via the symbol table.

8. If fred is declared as a 10x10 array of doubles, which of the following can be used to read a value from the keyboard and store the result in cell fred[2][3]?

   1.   ?    scanf("%f", fred[2][3]);
   2.   ?    scanf("%f", &fred[2][3]);
   3.   ?    scanf("%lf", &fred[2][3]);
   4.   ?    scanf("%lf", fred[2][3]);

9. If fred is declared as a 10x20 array of doubles, which of the following will not print out the value stored in fred[2][3]?

   1.   ?    printf("%f", fred[2][3]);
   2.   ?    printf("%f", *(fred+43));
   3.   ?    printf("%f", fred[43]);

10. What is the minimum length that a character array can be dimensioned for if it is to hold a string with N characters?

    1.   ?    N-1
    2.   ?    N
    3.   ?    N+1
    4.   ?    0 (the compiler will automatically allocated as much memory as necessary to hold the string)
