- c++ the following function header is for a function thattakes two pointers to double-precision, floatingpoint numbers x and y as parameters and does notreturn a value.void exchange( double *x, double y ) Select one: True FalsePYTHON CODE. KEEP OUTPUT SAME. Implement the following:1) Define a function sumValues() with an arbitrary parameter values.2) This function returns the sum of any number of values sent to this function.3) Call the function with 10 and 20 as arguments and print the result.4) Call the function with 10, 20, 30, and 40 as arguments and print the result. Example Output (10 and 20 are arguments)30 Example Output (10, 20, 30, and 40 are arguments)1004. Design a recursive function that accepts an integer argument, n, and prints every second number from n down to a minimum of 0. Assume that n is always a positive integer.
- 1 - Nuclear Power Plant (python) The nuclear powerplant at Threeyedfish will automatically run a program to print a warning message when the reactor core becomes unstable. The warning message reads: NUCLEAR CORE UNSTABLE!!! Quarantine is in effect. Surrounding hamlets will be evacuated. Anti-radiationsuits and iodine pills are mandatory. Since the message contains crucial information, it should be printed three times. To do this, write a function that prints this message. This function has to be used three times.In C++ A value-returning function a. must contain "return" followed by the value to be returned (or variable assigned to that value) b. must contain "return" followed by a constant c. must contain "value" followed by the value of the function d. must contain "void" followed by the value to be returned (or variable assigned to that value)assume the availability of a function is_prime. Assume a variable n has been associated with a positive integer. Write the statements needed to compute the sum of the first n prime numbers. The sumer should be associated with teh variable total. this should be done in Python. is_prime takes an integer as a parameter and returns True if and only if that integer is prime
- Solve the problems Solve the quadratic equation 2x^2 + 6x + 4 = 0. Implement a function that takes incoefficients A,B,and C forthequadratic equation Ax2 + Bx + C = 0 and computes the two solutions. Have the function return the number of valid (not NaN) solutions and fill in the return arguments so the smaller of the two solutions is first.Consider the function definition: void GetNums(int howMany, float& alpha, float& beta) { int i; beta = 0; for (i = 0; i < howMany; i++) { beta = alpha + beta; } } Describe what happens in MEMORY when the GetNums function is called.Calculus Please define the following function using lambda notation. { < up , down > , < on , off > , < high, low > , < hot , cold > }
- Consider the following recursive function. What does it calculate in terms of x, y, and z? 01: Private Function CalcRecurse(ByVal x As Integer, ByVal y As Integer, ByVal z As Integer) As Integer 02: If x <= 1 Then 'Assume that CalcRecurse always starts with x > 1 03: Return y 04: Else 05: Return z + CalcRecurse(x - 1, y, z) 06: End If 07: End FunctionEmulate the rolling of dice. [ C++ ] a) Write a roll function which accepts the number of dice sides as input and returns the result of a random dice roll of the specified size.b) Overload the roll function to accept the number of rolls as a second input parameter. The overloaded function should return a random value which is the sum of r rolls of an n sided die. For example 2d9 is 2 rolls of a 9-sided die.c) Test the first function with various dice sizes (see output).d) Test the second function with various values (see output).e) The program should generate new random values every time it runs. Note that dice values start at 1.Comments would also be greatly appreciated to help in explanation, thank you :)function myCompose(f,g){// TODO: return (f o g);// that is, a function that returns f(g(x)) when invoked on x.}
