Select the single best answer for each question.

1. Which of the following statements declares an array having 100 elements of type double?

   1.   ?    double fred[0...100];
   2.   ?    double[100] fred;
   3.   ?    double fred[0:100];
   4.   ?    double fred[100];

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

   2.   ?    N+1
   3.   ?    N
   4.   ?    N-1

3. Which of the following statements best describes what an array is?

   1.   ?    A collection of variables, all of the same data type, that are stored in a contiguous block of memory and share the same base name.
   2.   ?    A collection of variables, possibly of different data types, that all have the same name.
   3.   ?    A collection of variables, possibly of different data types, that are stored in a contiguous block of memory and share the same base name.
   4.   ?    A collection of pointers to multiple memory locations each of which contains the same type of data.

4. If sizeof(double) = 8 and sizeof(int) = 2, which of the following declarations requires 80,000 bytes of memory?

   1.   ?    double fred[1000][80]
   2.   ?    int fred[20000];
   3.   ?    double fred[80000];
   4.   ?    double fred[100][100];

5. Arrays are passed to functions

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

6. 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[43]);
   2.   ?    printf("%f", *fred+43);
   3.   ?    printf("%f", fred[2][3]);
   4.   ?    printf("%f", *(fred+43));

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

8. What is the largest index that can properly be used to access an element in an array declared as having N objects?

   1.   ?    0
   2.   ?    N
   3.   ?    N-1
   4.   ?    N+1

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

   1.   ?    'B'
   2.   ?    '\0'
   3.   ?    'b'
   4.   ?    'o'

10. 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.   ?    0x3FC0
    2.   ?    0x7032
    3.   ?    0x4032
