The Card Box Problem C++ you should write documentation for your program.    Using functions, write a program that prompts the user to enter the area of the flat cardboard. The program then outputs the length and width of the cardboard and the length of the side of the square to be cut from the corner so that the resulting box is of maximum volume. Calculate your answer to three decimal places. Your program must contain a function that takes as input the length and width of the cardboard and returns the side of the square that should be cut to maximize the volume. The function also returns the maximum volume.

// // Write a function that calculates the amount of money a person would earn over // a period of years if his or her salary is one penny the first day, two pennies // the second day, and continues to double each day. The program should ask the // user for the number of years and call the function which will return the total // money earned in dollars and cents, not pennies. Assume there are 365 days // in a year. // function totalEarned (years) { // Insert your code between here and the next comment block. Do not alter // // any code in any other part of this file. // Insert your code between here and the previous comment block. // any code in any other part of this file. Do not alter // // var years = parseInt(prompt('How many years will you work for pennies a day? ')); var totalDollarsEarned = totalEarned (years); alert('Over a total of ' + years + ', you will have earned $' + totalDollarsEarned);

python" You have an Internet connection with a download speed of 41 Megabits per second (Mbps) and you want to calculate how long it will take to download a files based on their size. Write a function named "download_time" that takes an integer as a parameter. The parameter represents the size of a file in Gigabytes that you want to download. The function should return the number of seconds it will take to download that file if your download speed is 41 Megabits per second. To convert the file size from Gigabytes to Megabits remember that 1 Gigabyte equals 1000 Megabytes and that 1 Megabyte equals 8 Megabits.

Swapping variables   Define a function named swap_values that takes four integers as parameters and swaps the first with the second, and the third with the fourth values. Then write a main program that reads four integers from input, calls function swap_values() to swap the values, and prints the swapped values on a single line separated with spaces. Ex: If the input is: 3 8 2 4 function swap_values() returns and the main program outputs: 8 3 4 2 The program must define and call the following function. def swap_values(user_val1, user_val2, user_val3, user_val4)

Python Help Write the function grade_average(test1,test2,test3,test4,test5) that returns the average of five test scores.Write the function letter_grade(grade) that returns the letter grade of a test score: if the test score is 100-90 it should return A, if the test is between 80-89 it should return B, if the test is between 70-79 it should return C, if the test is between 60-69 it should return D, and it should return F otherwiseWrite a main function that asks the user to enter five test scores and calls the average function to find the average of the five test scores. After returning the average, use letter_grade function to return the letter grade of the average grade.

IN C programming  Write a function that will take an integer as an argument and return the factorial of the integer. Then write another function that will take two integers as arguments and then return the ratio of the factorials of the first argument with the second one. You need to make two calls to the first function inside the second function to find the factorials of the numbers.

Code using c++ 3. From Person to People by CodeChum Admin Now that we have created a Person, it's time to create more Person and this tech universe shall be filled with people!     Instructions: In the code editor, you are provided with the definition of a struct Person. This struct needs an integer value for its age and character value for its gender. Furthermore, you are provided with a displayPerson() function which accepts a struct Person as its parameter. In the main() function, there's a pre-created array of 5 Persons. Your task is to ask the user for the values of the age and gender of these Persons. Then, once you've set their ages and genders, call the displayPerson() function and pass them one by one. Input 1. A series of ages and genders of the 5 Persons Output Person·#1 Enter·Person's·age:·24 Enter·Person's·gender:·M   Person·#2 Enter·Person's·age:·21 Enter·Person's·gender:·F   Person·#3 Enter·Person's·age:·22 Enter·Person's·gender:·F   Person·#4…
