Correct Answer: #include "dosh" main() { Char far *scr = ( char far *) 0xB8000000; Char *seg, *off; Seg = (char *) FP_SEG ( scr ); Off = ( char *) FP_OFF ( scr ); }
Correct Answer: Final
Explanation:
Once a method declared as Final cannot be overriden
Correct Answer: It is NOT appropriate to use assertions to validate command-line arguments
Explanation:
A is incorrect. It is acceptable to use assertions to test the arguments of private methods.
B is incorrect. While assertion errors can be caught, Sun discourages you from doing so.
Correct Answer: a
Correct Answer: 3
Explanation:
The Math.floor() function in JavaScript is used to round off the number passed as parameter to its nearest integer in Downward direction of rounding i.g towards the lesser value.
Hence, math.floor(3.6) = 3.
Correct Answer: An error would be reported in the statement k++ since arithmetic on void pointers is not permitted unless the void pointer is appropriately typecasted
Correct Answer: Use the typecast scr = (char far *) 0xB8000000;
Correct Answer: 1 2
Correct Answer: A typedef defines a new name for a type, and in simpler cases like the one shown below you can define a new structure type and a typedef for it at the same time typedef struct { char name[20]; int age; } emp; However, in the structure defined in this question, there is an error because a typedef declaration cannot be used until it is defined In the given code fragment the typedef declaration is not yet defined at he point where the link field is declared
Correct Answer: No, since the structure contains a char pointer while writing the structure to the disk using fwrite() only the value stored in the pointer n would get written When this structure is read back the address would be read back but it is quite unlikely that the desired string would be present at this address in memory
