i need this in programming c

You will write a program that will Calculate some of the costs for a road trip. .Assume the user will drive an average of 70 MPHH . The toll rate is 5 cents a mile .The user will stop and spend S15.00 every 4 hours for food and/or coffee The user will enter the number of miles, the cost of gas per gallon, and the miles per gallon(mpg) of the car You must have at least 7 user defined functions as follows: //Road trip //preprocessor directives #defineCRTSECURE NO WARNINGS #include - - #define SPEEDLIMIT 78 #define TOLLRATE "es #define ENERGYCOST 15.ee //Greet the user void Greeting) //Calculations for one road trip void OneRoadTrip); //get input (y or n) to continue void GetYesorNo(char *inputPtr); //Calculate the cost of the gas void CalculateGasCost (double miles, double 'gasCostPtr); //calculate the time in hours and minutes void CalculateTime(double miles, double *tripTinePtr, nt *hoursPtr, int *minutesPtr); //calculate the cost of food/energy void CalculateEnergyCost(double tripTime, double foodCostPtr); //calculate cost of tolls and return the total cost of gas, tolls, and food double CalculateCost (double miles, double gasCost, double foodCost, double tollCostPtr); Use function prototypes. Write comments for each function that will appear in the file before each prototype and again before each function definition. . . Be sure to comment your code adequately .Be sure to indent properly. Check your textbook examples to see how it should be done . Use meaningful variable names. NO Late Submission
