Correct Answer: None
Explanation:
Default constructors has no arguments
Correct Answer: 1
Explanation:
One. If there is only one entry possible in the bucket, when the collision occurs, there is no way to accommodate the colliding value. This results in the overlapping of values
Correct Answer: All the above
Explanation:
ll the above listed methods are used in storing sequential files
Correct Answer: 8
Explanation:
A binary tree with n nodes has exactly n+1 null nodes
Correct Answer: Insertion
Explanation:
Using insertion we can perform insertion sort, using selection we can perform selection sort, using exchange we can perform the bubble sort.But by using deletion we cannot perform any sort.
Correct Answer: C requires all the variables to be declared at the beginning of a scope but in c++ we can declare variables anywhere in the scope This makes the programmer easier to understand because the variables are declared in the context of their use
Correct Answer: The function declaration should be preceded by the keyword friendThe function definitions does not use either the keyword or the scope operator :: The functions that are declared with the keyword friend as friend functionThus, a friend function is an ordinary function or a member of another class
Correct Answer: 252
Explanation:
In this program, We are dividing the values of a and b, printing it.
Correct Answer: data types
Explanation:
The data types are mandatory for declaring the variables in the function pointers.
Correct Answer: d99
Explanation:
In this program, we have declared the values as integer instead of character, So it is printing as d99 but it will not arise an error.
