In this article we will be discussing the working, syntax and examples of list::emplace_front() and list::emplace_back() function in C++ STL.What is a List in STL?List is a data structure that allows constant time insertion and deletion anywhere in sequence. Lists are implemented as doubly linked lists. Lists allow non-contiguous memory allocation. List performs 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 ... Read More
The ord function in python gives the ordinal value of a character(ASCII). You can use this function to find the ascii codes as followsExamples = "Hello" for c in s: print(ord(c))OutputThis will give the output72 101 108 108 111
In this article we are going to discuss the set::value_comp() in C++ STL, their syntax, working and their return values.What is Set in C++ STL?Sets in C++ STL are the containers which must have unique elements in a general order. Sets must have unique elements because the value of the element identifies the element. Once added a value in set container later can’t be modified, although we can still remove or add the values to the set. Sets are used as binary search trees.What is set::value_comp()?value_comp() is an inbuilt function in C++ STL which is declared in header file. ... Read More
Python provides straightforward functions to convert Decimal to Binary, Octal, and Hexadecimal. These functions are −Binary: bin() Octal: oct() Hexadecimal: hex()ExampleYou can use these functions as follows to get the corresponding representation −decimal = 27 print(bin(decimal),"in binary.") print(oct(decimal),"in octal.") print(hex(decimal),"in hexadecimal.")OutputThis will give the output −0b11011 in binary. 0o33 in octal. 0x1b in hexadecimal.

You can create the multiplication table for any number using a simple loop. exampledef print_mul_table(num): for i in range(1, 11): print("{:d} X {:d} = {:d}".format(num, i, num * i)) print_mul_table(5)OutputThis will give the output5 X 1 = 5 5 X 2 = 10 5 X 3 = 15 5 X 4 = 20 5 X 5 = 25 5 X 6 = 30 5 X 7 = 35 5 X 8 = 40 5 X 9 = 45 5 X 10 = 50
You can create a list of the three numbers and call the max method to find the largest among them. examplemy_list = [10, 12, 3] print(max(my_list))OutputThis will give the output −12ExampleIf you want to calculate it yourself, you can create a simple function likedef max_of_three(a, b, c): if a > b and a > c: return a elif b > c: return b else: return c print(max_of_three(10, 12, 3))OutputThis will give the output −12

You can get the current date and time using multiple ways. The easiest way is to use the datetime module. It has a function, now, that gives the current date and time. exampleimport datetime now = datetime.datetime.now() print("Current date and time: ") print(str(now))OutputThis will give the output −2017-12-29 11:24:48.042720You can also get the formatted date and time using strftime function. It accepts a format string that you can use to get your desired output. Following are the directives supported by it.DirectiveMeaning%aLocale's abbreviated weekday name.%ALocale's full weekday name.%bLocale's abbreviated month name.%BLocale's full month name.%cLocale's appropriate date and time representation.%dDay of the month ...
