Using a lambda expression, complete the mul_by_num function. This function should take an argument num and return a one argument function that multiplies any value passed to it by num. Its body must be one line long: def mul_by_nunum): Returns a function that takes one argument and returns num times that argument. >>> x = mul_by_num(5) >>> y = mul_by_num(2) >>> X (3) 15 HIH >>> y(-4) -8 win "*** YOUR CODE HERE *****"

C++ program Hi i need help making the following function,   ------>>>>>>    friend bool operator<(Date& date1, Date& date2); the function is supposed to compare 2 date objects of the Date class ............................... It is supposed to overload the < operator to compare 2 Date objects. The comparison shall return true only  if the Date object on the left represents a date earlier than the Date object on the right. The comparison shall not update either Date object.  please help I provided all my code below: The following are the 3 libraries of my program --------------------------------------------------------------------------------------------------------------------------------------------------------- DATE.H file: #ifndef DATE_H#define DATE_H#include <string>using namespace std; class Date {  private:    string entered_date;    int month_, day_, year_;  public:   Date();   Date(const string& entered_date);  friend bool…

In C programming!! Function prototype and implementation for the calculateDivisors function that takes in an integer parameter, calculates the sum of its divisors, and returns that sum (as an integer value) A structure that represents what is represented on each line of output, e.g., o Linenumbero Sumofthedivisorsforthatlinenumbero Characterarraycontaining“Perfect”,“Deficient”,or“Abundant” Pointer declared within the main that will be used to point to an area of memory containing a collection of these structs Dynamically allocated memory for the number of structs necessary You will assign values to each struct via the pointer A loop that goes from X to Y, where X and Y are the numbers inputted by the user at the command line argumento Note:becausetheuserisenteringinputhere,youwillneedtocheckforreasonableness: § The value of X must be greater than or equal to 2§ The value of Y must be greater than the value of X§ If either one of the above conditions are not met, you should…

Set-up and implementation code for a void function MaxYou are not required to write a complete C++ program but must write and submit just your responses to the four specific function related questions below: QC1: Write the heading for a void function called Max that has three intparameters: num1, num2 and greatest. The first two parameters receive data from the caller, and greatest is used to return a value as a reference parameter. Document the data flow of the parameters with appropriate comments*. QC2: Write the function prototype for the function in QC1. QC3: Write the function definition of the function in QC1 so that it returns the greatest of the two input parameters via greatest, a reference parameter. QC4: Add comments to the function definition* you wrote in QC3 that also states its precondition and postcondition.
