Data Encapsulation
Which one of the statements concerning data encapsulation is FALSE? A. Data encapsulation lets the programmer create an object and then provide an interface that other objects can use to invoke the methods provided by that object. B. Programmers can change the internal working of an object, but this may be transparent as long as the interface remains unchanged. C. Data encapsulation works well for...

E is false, because encapsulation decreases the complexity of the program (encapsulation is to wrap data and associated functions into a single unit called class)

Program Crash
When can it happen that before calling main function itself program gets crashed?
ajrobb
- Sep 22nd, 2010
I agree.However, there is a difference between global and static. Global objects have global linkage and can be referenced anywhere in the program. Static objects can have access restricted to the file or function where they are defined.

All global static objects will be created before main().Program has problem to instantiate them.

Memory Allocation
Why is it suggested not to use malloc() or calloc() in C++ for memory allocation?
ajrobb
- Sep 22nd, 2010
There may be a clash between malloc() and new as they don't HAVE to use the same heap library routines. Also, for arrays of classe objects, new invokes the default constructor. For single class objects new allows you to choose a different constructor.

Operators
In the following code fragment, which is the calling object for the less-than operator?string s1, s2;if( s1 < s2 )Choose one answer. a. s1 b. < c. s2 d. none
bhatiapy
- Nov 25th, 2010
S1 is the calling object. The compiler converts s1<s2 to below function call :- s1.operator<(s2);
a_soni
- Nov 19th, 2010
S1. As this is the object which appears on the left side of the operator, this is the calling object for it. Whereas S2 is the object which is passed as an parameter to the '<' operator function.

Classes
What error is caused by the following code ?class TemperatureList { public: TemperatureList( ); private: double * list; int size;};void func(Money amount);[...]int main{ TemperatureList list1; func(list1); return 0;}Choose one answer. a. double free b. divide by zero c. illegal argument d. no error
amithere007
- May 26th, 2011
The function func is taking an object of Money class which is not defined in this scope so that will give a compilation error. It will give the error as "Money' was not declared in this scope ".

c. illegal argument list1 object passed to a func() is diferent type than the func() param should be.func() expects an object of Money type.

You have an array having numbers 1 to 100 but one number is missing? find out the missing number?
harshitha
- Feb 7th, 2014
Calculate the sum of 1 to 100 i.e sum=(1+100)*(100/2)=5050
Code- span style="color: #ff0000;">"missing number is %d
- ",temp);
- getch();
- }
std.approach
- Jun 4th, 2013
Its simple.
1. do calculate the sum of numbers from 1 till 100. is about (1+100)*(100/2)=5050
2. iterate and summarize all elements of container (array).
3. each number is unique in the container, so the difference between 5050 and the sum (from point 2) gives us an answer. -
