  Sum of Digits of a Five Digit Number Objective The modulo operator,%, returns the remainder of a division. For example,  4 % 3 = 1  and  12 % 10 = 2 . The ordinary division operator,  / , returns a truncated integer value when performed on integers. For example,  5 / 3 = 1 . To get the last digit of a number in base 10, use as the modulo divisor. Task Given a five-digit integer, print the sum of its digits. Input Format The input contains a single five digit number,  . code- #include   < stdio.h > int   main ()   {    int   num ;    int   digit ;    int   sum = 0 ;    scanf ( "%d" ,   & num );       while ( num > 0 )    {      digit   =   num   %   10 ;      sum   =   sum + digit ;      num   =   num   /   10 ;    } ...

  How to Calculating the area of a circle using Python:- The area of the circle is the number of square units inside the circle, can be calculated using the radius and diameter. The formula for evaluating the area of a circle is Area of circle using radius=     Pi*r*r     ( r is the radius of the circle) Area of the circle using diameter=    1/4*Pi*d*d   ( d is the diameter of the circle) Pi is a Greek letter and the value of Pi is equal to 3.14159265359. In the program, we will be initiating Pi as a global variable or we can simply import from the math module present in python. The syntax for importing pi from math module:   from import math. ALGORITHMS:- 1 .Input radius/diameter.     2 . Calculate the area of a circle using the formula.              area= pi*r*r(if radius is given as input).            ...

  How to Find whether a given number is Positive or Negative in python:-         In this Python Program, We will be discussing how to find a user-entered number that is positive or negative. We will check by using an if-else block and compare the given number with zero. If the user entered number is greater than zero then the number is positive. Else, the number is negative. ALGORITHMS:- Step 1 . Start. Step 2 . Insert the number. Step 3 . If the number is greater than zero, then print, “The number is Positive”. Step 4 . Else print, “You entered Negative”. Step 5 . Stop. CODE: -                                                                                                        num =  int ( inpu...
