Write a program in C that has three float variable (place random values in them) and that will call the functions below using these variables as arguments. Create a function named hotdog that takes three float arguments and returns the middle value of them. Call the function pizza on the three variables and output the function return to the screen.

Write a function that has a single input argument grade. If the user's input is a numeric number, the grade letter should be displayed to the command window depending on the value of grade, as shown in the table below. Otherwise, MATLAB should stop the execution and send an error message: "invalid input" to the command window. Grade Grade Letter Grade 2 90 A 90 > Grade 2 80 80 > Grade > 70 70> Grade 2 60 60> Grade Grade >100 or Unknown Grade using namespace std; int main) ( int score; char grade; coutss"Enter score: "; cin>>score; if(score100X cout<

Write a program in C to assist in circuit calculations (No previous knowledge in circuits is required)as follows:Create a function named menu that has no parameters and returns a character. The functiondisplays the following options:- R to calculate series resistance (R = R1 + R2).- P to calculate parallel resistance (1/R = 1/R1 + 1/R2).- T to calculate series capacitance (1/C = 1/C1 + 1/C2).- S to calculate parallel capacitance (C = C1 + C2).- V to calculate voltage across a resistor (V = I x R).- C to exit.The function menu should be displayed at the beginning of the program and every time a menuoption is carried out (redisplay the menu to do more calculations). The menu function shouldreturn the user choice to main.Create a function named validate that has no parameters and that returns a float. The functionrepeatedly asks the user for a value until a positive nonzero value is entered, then the functionreturns that value.Create a function named superman that accepts two float…

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
