The following program
main()
{
static char a[3][4] = {"abcd", "mnop", "fghi"};
putchar(**a);
}
A. | will not compile successfully |
B. | results in run-time error |
C. | prints garbage |
D. | none of the above |
Option: D Explanation : *a points to the string "abcd".**a is the first character of "abcd", which is the character 'a ' Click on Discuss to view users comments. |
C does no automatic array bound checking. This is
A. | true |
B. | false |
C. | C's asset |
D. | C's shortcoming |
Option: D Explanation : C does no array bound checking. Because of this, one can access fifth clement of an array that is declared to he of lesser size. Click on Discuss to view users comments. |
If n has the value 3, then the statement
a [++n] = n++ ;
A. | assigns 3 to a [5] |
B. | assigns 4 to a [5] |
C. | assigns 4 to a [4] |
D. | what is assigned is compiler-dependent |

Choose the statement that best defines an array
A. | It is a collection of items that share a common name |
B. | It is a collection of items that share a common name and occupy consecutive memory location |
C. | It is a collection of items of the same type and storage class that share a common name and occupy consecutive memory locations |
D. | None of the above |
Option: C Explanation : Click on Discuss to view users comments. |
Choose the correct statements
A. | Strictly speaking C supports 1-dimensional arrays only |
B. | An array element may be an array by itself |
C. | Array elements need not occupy contiguous memory locations |
D. | Both (a) and (b) |
Option: D Explanation : C supports 1-dimensional arrays only. But, the array element can be an array by itself. Using this, one can simulate multi-dimensional arrays. Though at the user level, we use 2-dimen-sional arrays, the compiler interprets this as a 1-dimensional array, each of whose element is a 1-dimensional array. As a matter of fact, a declaration like char [3] [4] , will be interpreted as a 1-dimensional array of size 3 (rather than 4)—each element being a character array of length 4.
