How many times will the following code print "Welcome to Java"?
int count = 0;
while (count++ < 10) {
System.out.println("Welcome to Java");
}
a. 8
b. 9
c. 10
d. 11
e. 0
c The count is initialized to 0 before the loop. (count++ < 10) increments count by 1 and uses the old count value to check if count < 10 . So, the loop is executed 10 times for count from 0 to 9 . The correct answer is C.

Answer the following statements true (T) or false (F)
1. An uncaught exception in C++ is ignored. 2. If an exception is thrown in a function, say, f(), but not handled there, the exception is propagated to the function that called f(). 3. A circumstance in C++ where an exception is thrown must be an error. 4. When an event occurs that cannot be managed locally, an exception may be thrown. Throwing the exception object transfers control and information gleaned locally to some calling program unit that manages the event, or the program terminates. 5. In C++, an exception object can be a user-defined type or any type that is built-into C++ language.
