- Do the following in Haskell and show type signature! Use guards to create a function called guess which takes one Int parameter. If the parameter is a multiple of 3 print “Multiple of 3.” If the parameter is a multiple of 5 print “Multiple of 5.” If the parameter is a multiple of 7, print “Multiple of 7.” Otherwise print “Not a multiple of 3,5,7”In C++, Given the following function prototype: void testDefault(int a, int b = 7, char z = '*'); Indicate if each of the following function calls are valid or invalid a) testDefault(5); b) testDefault(); c) testDefault(6, '#'); d) testDefault(0, 0, '?');In C++, please revise/fix the program below according to the instructions and all the criteria. I believe the problem is in int main(). Thank you. Instruction Write and test a function that returns a copy of its string parameter with no repeated characters. The functions ignore case when they compare letters. The functions return strings whose letters are upper case. Write 2 versions of the function: string remDups(const string& original); void remDups(const string& original, string& nodups); Suppose the original string is “Myrtle has big feet” The function returns MYRTLE HASBIGF Test the functions thoroughly. Criteria compile, run, test the test program compiles, runs, and calls both versions of the function without crashingthe test program tests the functions thoroughly function parameters and returns one function has one constant string reference parameter and returns a stringone function has one constant string reference parameter, one string reference parameter and…
- What does it mean by line1 of the following C++ statements. void y (int k) //line1 { if ((k%2)==0) cout<< k << " is an even number"; else cout<< k << " is an odd number"; } A.Function name y receives an int-type parameter. The function y does not return anything to the caller. B.Function name y receives an int-type parameter. The function y does return an int-type value to the caller.Engineers often measure the ratio of two power measurements in decibels, or dB, which can be calculated as follows:dB= log10P2/P1Where P2 is the power level being measured, and P1 is some reference power level. Write a c++ programe contain function that calculates the level. The function’s prototype is as follows:double dBCalculator (double P1, double P2);Then, call dBCalculator from the main function to find the power ratio for the measurements from 1 to 20 Watts, in 2 Watt steps. You can assume that the reference power P1 is 1 Watt.7. What will be the output of the following C++ code? #include <iostream> using namespace std; int main ( ) { static double i; i = 20; cout << sizeof(i); return 0; }
- Please do the following and show execution code and output! Write two Haskell functions to calculate ticket prices. Tickets for those ages 12 and under are $8.50, tickets for those between 13 and 65 are $14.50 and those older than 65 are $9.00. The second function should calculate tax – assume tax is 12%. Using function chaining to calculate the total cost. The main function should ask what type of ticket the person wants (child, adult, or senior) and call the functions that you wrote. Show the type signatures of the functions you write.a) What is the risk of using strcpy() in C given the code below? void f1(char *str2) { int y; char str1[10]; strcpy(str1, str2);In c++ only Please create a class multiplication with three overloaded functions to multiply two or three integers or two double literels. Please provide output and code screenshot
- Using the following description, please replace the return line in C code; /* * conditional: same as x ? y : z * Examples: * conditional(0,3,4) = 4 * conditional(1,3,4) = 3 * conditional(4,5,6) = 5 * conditional(-1,7,8) = 7 * Legal ops: ! ~ & ^ | + << >> * Max ops: 16 */ int conditional(int x, int y, int z) { return 2 } You cannot: 1. Use any control constructs such as if, do, while, for, switch, etc. 2. Define or use any macros. 3. Define any additional functions in this file. 4. Call any functions. 5. Use any other operations, such as &&, ||, -, or ?:, not listed in the the "Legal ops" list for the function. 6. Use any form of casting. 7. Use any data type other than int.Hello. I need help with a dice roller program in C++. The program compiles and mostly works, but for negative numbers, I want to just print Illegal value entered. But it also prints the rolling and total, which I should only show with positve numbers not negative numbers. How do I stop the function when a negative number is entered and move on to the next function?Need help solving the following in C++. When the given integer variable numProducts is: greater than 12, output "Must split order". between 5 inclusive and 12 inclusive, output "Mid-sized box". between 0 exclusive and 4 inclusive, output "Small box". less than or equal to 0, output "Bad input". End with a newline. Ex: If the input is 13, then the output is: Must split order #include <iostream>using namespace std; int main() { int numProducts; cin >> numProducts; /* Your code goes here */ return 0;}
