The type specifier for boolean in c++ is bool. You can use it as −bool myBoolean = true;
Use of indented blocks is an important feature of Python. Indent level of the block is more than previous statements. Hence, if multiple if statements are present in a program in nested fashion, each subsequent indented block will have increasing level of indent.if expr1==True: if expr2==True: stmt1 else: if expr3==True: stmt2 else: if expr3==True: stmt3 else: stmt4
Given is the task to show the functionality list insert( ) function in C++ in STL.What is List in STLList are containers that allow constant time insertion and deletion anywhere in sequence. List are implemented as doubly linked lists. List allow non-contiguous memory allocation. List perform better insertion extraction and moving of element in any position in container than array, vector and deque. In List the direct access to the element is slow and list is similar to forward_list, but forward list objects are single linked lists and they can only be iterated forwards.What is insert( )The list insert( ) ...

Python's break keyword is used as decision control statement. It causes the remaining iterations to be abandoned and control of execution goes to next statement after the end of loop. Invariably it is executed conditionally and appears inside if block within a loop.while expr==True: stmt1 stmt2 if expr2==True: break stmt3 stmt4 However it can't be used in an if block if it is not a part of loop.
Python's continue statement is a loop control statement. It causes starting next iteration of loop after abandoning current iteration. Invariably is is executed conditionally i.e. in if blockwhile expr==True: stmt1 stmt2 if expr2==True: continue stmt3 stmt4However, it can't be used in an if block if it is not a part of loop. If used, interpreter will throw syntax error.
Given is the task to show the functionality of deque resize( ) function in C++ STL.What is DequeDeque is the Double Ended Queues that are the sequence containers which provides the functionality of expansion and contraction on both the ends. A queue data structure allow user to insert data only at the END and delete data from the FRONT. Let’s take the analogy of queues at bus stops where the person can be inserted to a queue from the END only and the person standing in the FRONT is the first to be removed whereas in Double ended queue the ...

The symbols > are defined as left and right shift operators respectively in Python. They are bitwise operators. First operand is a bitwise representation of numeric object and second is the number of positions by which bit formation is desired to be shifted to left or right.The >> a=60 >>> bin(a) '0b111100' >>> b=a> b 240 >>> bin(b) '0b11110000'You can see two bits on right set to 0On the other hand >> operator shifts pattern to right. Most significant bits are set to 0>>> a=60 >>> bin(a) '0b111100' >>> b=a>>2 >>> b 15 >>> bin(a) '0b111100'
The == symbol is defined as equality operator. It returns true if expressions on either side are equal and false if they are not equal>>> (10+2) == 12 True >>> 5*5 == 5**2 True >>> (10/3)==3 False >>> 'computer'=="computer" True >>> 'COMPUTER'.lower()=='computer' True
In Python, // is defined as floor division operator. It returns integer part of a floating point result of division. For example 10//3 returns 3>>> 10//3 3 >>> 125.5//2.5 50.0 >>> 12.5//1.5 8.0However in case of negative division, returned value is rounded towards negative infinity.>>> -10//3 -4 >>> -73//9 -9
