6.Engineers often measure the ratio of two power measurements in decibels, or dB, which can be calculated as follows: dB = P₂ log10 P1 Where P2 is the power level being measured, and P₁ is some reference power level. Write a 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 0.5 Watt steps. You can assume that the reference power is 1 Watt.

4. You are given the following functions: int functionA(int a) { printf ("a-sd\n", a); if (a==1) return 1; else return functionB (a-1) *2; int functionB (int b) { printf ("b=3d\n",b); if (b--1) return 1; else return functionA (b-1) *3; Write the main function. Your main function should prompt the user for input and then call the mutual recursion by passing in the user's input. The guidelines are described below. int main () { //declare int a to receive user input and int result to receive result of mutual recursion //using a while loop, prompt user for input. The number entered //must be bigger than 1, otherwise repeat user input with an error //message. //call functionA () with int a as input argument. Receive the result in int result. //print result return 0;

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
For the following code can you change the factors that impact the total construction cost section into a function(define a function). Where the mean can be entered through by asking for the inputs of the mean value for each of the factors. (i.e., "Please enter the mean value for material", "Please enter the mean value for labour".. etc.). Follwoing this the standard deviation of the factors is calculated and this is all done in a function.
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.

NOTE: Solve this as soon as possible, I need this urgently. (a). Write a function that takes an integer as input and finds whether it is a prime number or not . Function should return 1 if number is prime , 0 otherwise. In main(), ask the user to enter the number and call the funcltion. Based upon the value returned by the function , main() will display on screen, if the number is prime or not.
