Write a function in Ruby language that takes two parameters, string str, and an integer n. The function should return a string that contains n copies of the string str.

In C++ Even if a problem does not directly tell you to use a function, you should aim to do so regardless. 2520 is the smallest number that can be divided by each of the numbers from 1 to 10 without any remainder. What is the smallest positive number that is evenly divisible by all of the numbers from 1 to 20?

In C++, Write a function named that accepts argc and args with the same data type as command line arguments (int argc, char * args[]). It will return two boolean values. It checks whether each of command line argument ending with a comma (‘,’) or not. If they all are, it will return true. Otherwise, it returns false. It will also return true if there is no argument is given. In addition, it also returns another boolean flag indicating whether one of the arguments is just a comma only.For this question, you are not allowed to use string class and its method or string function such as strlen.

This is for my C++ 2 class, so still a beginner C++ program: Case Manipulator Write a program with three functions: upper, lower, and flip. The upper function should accept a C-string as an argument. It should step through all the characters in the string, converting each to uppercase. The lower function, too, should accept a pointer to a C-string as an argument. It should step through all the characters in the string, converting each to lowercase. Like upper and lower, flip should also accept a C-string. As it steps through the string, it should test each character to determine whether it is upper- or lowercase. If a character is uppercase, it should be converted to lowercase. If a character is lowercase, it should be converted to uppercase. Test the functions by asking for a string in function main, then passing it to them in the following order: flip, lower, and upper.

In python, write a function that receives three parameters: name, weight, and height. The default value for name is James. The function calculates the BMI and returns it. BMI is: weight/(height^2). Weight should be in kg and height should be in meters. For instance, if the weight is 60 kg and the height is 1.7 m, then the BMI should be 20.76. The function should print the name and BMI. The function should return 'BMI is greater than 22' if the MBI is greater than or equal to 22. Otherwise, the function should return 'BMI is less than 22'. Call the function and print its output.

C Programming Write a program that reads an integer from the user (keyboard), namely n. Yourprogram should print all positive numbers that are smaller than n and whosedigits sum up to a perfect square number.(An integer is a perfect square if it hasan integer square-root for example 25) You should print the numbers in ascendingorder and print their digits separated by ":" symbol from the least significant digitto the most significant digit on the same line as the number. At the end of eachline you should also print the sum of the digits of the number. Example:If the user enters n : 30, then the output should be as follows:1 1 14 4 49 9 910 0:1 113 3:1 418 8:1 922 2:2 427 7:2 9

In C++, Given the following mystery function, what is the output if the number passed to the function is 7: int mystery(int number) { if (number == 0 || number == 1) return number; else return mystery(number - 1) + mystery(number - 2); }

create a passphrase generator on c++ that follows this. Please make sure the code works on c++ visual studios DicewareTM is a method for picking passphrases that uses ordinary dice to select words at random from a special list called the Diceware Word List. Each word in the list is preceded by a five digit number. All the digits are between one and six, allowing you to use the outcomes of five dice rolls to select a word from the list. Here is a short excerpt from the English Diceware word list: 16655 clause 16656 claw 16661 clay 16662 clean 16663 clear 16664 cleat 16665 cleft 16666 clerk 21111 cliche 21112 click 21113 cliff 21114 climb 21115 clime 21116 cling 21121 clink 21122 clint 21123 clio 21124 clip 21125 clive 21126 cloak 21131 clock The complete list contains 7776 short words, abbreviations and easy-to-remember character strings. The average length of each word is about 4.2 characters. The biggest words are six characters long. The English list is based on a longer word list...

In Haskell: Code a function "rangeProduct" that takes two arguments. The function should return 0 if the second argument is smaller than the first, otherwise it should return the product of the range between two numbers, ex: rangeProduct 3 5 --> 60 (because 3*4*5 = 60) What to do for negative numbers to do (if anything) is up to you. Write the program without recursion first and then write it with recursion.
