C++ Programming

Written in C Please   Create a calculator program as follows.Create a menu function named kitten ( function should display the menu options and return the userselection with the following options. Prototype int kitten(void); ) :1 to calculate the number of real solutions for a quadratic equationPrototype: void fluffy(float a, float b, float c);2 to calculate the resistance in series for two or more resistors (no limit on number of resistors)Prototype: float series(float a, float b);3 to calculate the resistance in parallel for two or more resistors (no limit on number of resistors)Prototype: float parallel(float a, float b);4 to calculate the total of raising a value to an integer power value.Prototype float frisky(float x, int y);5 to exit programRepeatedly display the menu after each calculation until option 5 is entered.YOU HAVE TO CREATE AND USE ALL FIVE FUNCTIONS.Option 1:Ask the user for and store the three numerical coefficients of a quadratic equation and store them inthree…

Mathematical functions introduced in chapter 4 can be used in the mathematical calculations and simulations of the engineering and scientific problems. In these cases, we formulate the mathematical problem and then use the computer for calculations and simulations. Can a computer code solve the math problem and come up with mathematical formulas, i.e. can a computer program do what a mathematician does?

Within the tutorial casino craps game pseudocode, where should you place the pseudocode that performs the task of 'Get if the player won or lost', and how (in pseudocode) should this task be implemented? a.) In Function play, with pseudocode function play()  ...  set a local variable to won or lost b.) In Function play, with pseudocode function play() ...  return if the player won or lost c.) In Loop until Games Played = Times to Play, with pseudocode Loop until Games Played = Times to Play ...  If the player won ... Set "Get if the player won or lost" to won  Else if player lost  ... Set "Get if the player won or lost" to lost d.) In Loop until Games Played = Times to Play, with pseudocode Loop until Games Played = Times to Play ... If the player won  ...  Else if player lost  ... Set "Get if the player won or lost" to won or lost

Why is it necessary to create function prototypes in a program with user-defined functions?
