You shouldnot define any functions. It has an if and anelse. Whatever conversion you did, give theuser the option to do it in either direction,for example, dollars to yen and yen todollars. Have the user first input a code totell which direction they want to convert.The code could be a 1 or a 2 or it could bean appropriate letter. Give the userinstructions as to what code to input.

This is a simple use of if and else statements. The program in Java is given below

Write a function that takes the current date and corrects the number of days, if it's wrong. The function must return true if the date passed to it is a valid date and false, if not. The main function uses the returned value to either print "Date validated", if a valid date was entered or "Invalid date entered. Changed to ", followed by the modified date.
Write a program that has three functions. The first ask the user to enter a temperature in degrees celcius. The second takes a single parameter that is a temperature in degrees Celsius and returns the corresponding temperature in Fahrenheit. The thirsd function takes one parameter, a temperture in celsius and print the temperature in Celsius along with the corresponding temperature in Fahrenhiet. This function will use the second function. Then write a complete program that asks the user for a temperatre in Celsius and prints the corresponding temperature in Farenheit.
Write a function that has a single input argument grade. If the user's input is a numeric number, the grade letter should be displayed to the command window depending on the value of grade, as shown in the table below. Otherwise, MATLAB should stop the execution and send an error message: "invalid input" to the command window. Grade Grade Letter Grade 2 90 A 90 > Grade 2 80 80 > Grade > 70 70> Grade 2 60 60> Grade Grade >100 or Unknown Grade using namespace std; int main) ( int score; char grade; coutss"Enter score: "; cin>>score; if(score100X cout<
Write a function called orbit that takes three inputs and returns three outputs. Our function is related to a planet that is in orbit around a star. Your function should take information about your planet’s orbit and tell us how long that orbit will take. Your three inputs should be: - The major axis radius, major. - The minor axis radius, minor. - The planet’s orbital velocity, velo, in meters per second. Your outputs should be the length of one year on that planet, in days, using three approximations for the perimeter of an ellipse.A circular approximation, circTime. - Using Ramanujan’s1 first approximation, ram1Time. - Using Ramanujan’s second approximation, ram2Time
For each of the 4 functions below, Re-code each one to make it programmer friendly, using standard coding conventions, and documentation. Document each function with: a description of what it does (one sentence) and how it works (no more than 3 sentences). Also, provide a precondition: and a postcondition: statement. (See example for the setTime function below.) 1. 2. setTime(int hours, int minutes, int seconds); //Function to set the time //The time is set according to the parameters //Precondition: All parameters are valid numbers, within the range of clock hours (1-12), minutes (0 - 59), and seconds (0 - 59). //Postcondition: The clockType instance stores the hours, minutes and seconds. // If any of the parameters are not valid the time values will be set to zeros. int _1 (double x) {return (int) (x + 0.5); }; int _2 (char* s) {char*t = s; while (*t!='\0') {t++; }return t-s;}; 3. long 3 (int x,int y) {long n=1; for (int i = 0;i < y;i++) {n*=x; } return n; };
Write a set of functions that calculate the cost of movie tickets for a family. Using a loop, keep asking: The age of the movie goer. Based on this age, you will charge them these amounts: Under age 3, the ticket is free. If they are between 3 and 12, the ticket is $10.25. If they are over age 12, the ticket is $15.50. If they are 55 or older, the ticket is $12. If they buy at least 4 tickets, they receive a 20% discount. Then, keep a running_total that is output to the screen after each age has been entered. This running_total should be accessed through the functions using a pass-by-reference variable: &running_total The other function parameter variables are to be pass-by-value. Tell them to enter a zero when they want to stop. Finally, calculate the total cost including a 7.5% sales tax. and output it to the screen. Be sure that the code is broken up into functions with good comments. Put as little code in main() as you can get away with and still make sense.…
Write the followings as separate three functions that1. checks if an integer is five-digit and returns the result as an integer value (1 for true, 0 forfalse) (hint: you can either check the range or find the length of the number)2. returns the sum of the digits of any given integer (hint: use modulus and division operators)3. takes an integer as its first parameter, returns the left most and right most digit of thatnumber. (Notice that it returns 2 results at the same time) (hint: use pointers as function parameters,call the function by references)Write a main that uses the above 3 functions to find the sum of the digits and displays the left most andright most digits of given integers. The program stops when a five-digit number is entered.Example Run:Enter a digit number (to stop enter a five-digit number): 456735Sum of digits = 30Left most digit is: 4Right most digit is: 5 Enter a digit number (to stop enter a five-digit number): 142212Sum of digits = 12Left most digit is: 1Right…
Write a function called Strange with two parameters A and B, where B has the default value of 100. The value returned from the function is A-B if A is bigger than B, but returns B-A otherwise. (Note that there will be no print statements in this function, and you will be penalized if you use them.)write this function with only the def and return statements, but no other lines of code. Do not use: value1 if condition else value2
Write a function that asks the user for their birthday month and day and then the function should call a nested function to find out the person’s zodiac sign. Test your program with some user input. Aries: March 21 - April 19 Taurus: April 20 – May 20 Gemini: May 21- June 21 Cancer: June 22- July 22 Leo: July 23 – August 22 Virgo: August 23 – September 22 Libra: September 23 – October 23 Scorpio: October 24 – November 21  Sagittarius: November 22 – December 21 Capricorn: December 22 – January 19 Aquarius: January 20 – February 18 Pisces: February 19 – March 20
You are given 2 out of 3 angles in a triangle, in degrees. Write a function that classifies the missing angle as either "acute", "right", or "obtuse"based on its degrees. An acute angle is less than 90 degrees. A right angle is exactly 90 degrees. An obtuse angle is greater than 90 degrees (but less than 180 degrees). Example: missing_angle(27, 59) → obtuse WRITE IN PYTHON PLEASE
Design a function called intdiv() which takes a dividend and a divisor as parameters and returns the result and remainder (2 integers) as a tuple. E.G. given 9/2 equals 4 remainder 1:9 is the dividend, 2 is the divisor (parameters), 4 is the result and 1 is the remainder (values returned as a tuple).Write program statements which test this function by calling it twice with different parameters, and printing the returned values each time.
