Question

This is done in c programming and i have the code for the programs that it wants at the bottom i jut dont know how to call the functions

Program 2:Tip,Tax,Total

int main(void)
{
   // Constant and Variable Declarations

   double costTotal= 0;
   double taxTotal = 0;
   double totalBill = 0;
   double tipPercent = 0;

   // *** Your program goes here ***
   printf("Enter amount of the bill: $");
   scanf("%lf", &costTotal);
   printf("\n");

   // *** processing ***
   taxTotal = 0.07 * costTotal;
   totalBill = costTotal + taxTotal;
   tipPercent = 0.15 * totalBill;
   totalBill = taxTotal + costTotal + tipPercent;

   // *** output ***

   printf("Based on a bill of $%.2lf, The calculated amounts are:\n", costTotal);
   printf("Tip = $%.2lf\n", tipPercent);
   printf("Tax = $%.2lf\n", taxTotal);
   printf("Total = $%.2lf\n", totalBill);
   printf("\n");

   return 0;
} // end main()

Program 3: Minutes,hours,days

   double numDays = 0.0;
   int const NUMSECMIN = 60;
   int const NUMSECHOUR = 3600;
   int const NUMSECDAY = 86400;

   // *** Your program goes here ***
   printf("Enter the number of seconds: ");
   scanf("%d", &numSeconds);
   printf("\n");
  
   // ***processing***
   numMins = numSeconds / NUMSECMIN;
   numHours = numSeconds / NUMSECHOUR;
   numDays = numSeconds / NUMSECDAY;

   if (numSeconds >= 1) {
       printf("The number of seconds you entered, %d, is %.2lf minutes.\n", numSeconds, numMins);

   }
       printf("\n");

   return 0;
} // end main()

Progs 2,3, 4 ASSIGNMENT Write menu-driven program to allow the user to select and run program from one of the first 3 ohapters of CPT 234. Create a function to display a menu of choices, and have the function return the choice made by the user. Also create a void function to take the menu choice and run the desired program. Invoke the menu function, and pass the menu choice to the 2nd function. Put the above functions in a loop so that the menu will continue to display (and the program will continue to run) until the user selects-1 (or any negative value). When the program ends, display Good bye! Create 3 other functions for the 3 chapter programs - TipTaxTotal (Chapter 2). MinutesHoursDays (Chapter 3), and CaloiesBurned (Chapter 4). Each of these functions will accept no arguments and will also return nothing. Follow the prior program instruations for each of these programs The Chapter 3 program will use a decision to validate that the number of seconds is greater than 0, and if not the Chapter 3 program will display a message. end, and return to the menu Menu choices that are positive numbers (other than 2, 3, or 4) will do nothing and return to the menu.

Answer 1

void tip_tax_total()
{
   // Constant and Variable Declarations

   double costTotal= 0;
   double taxTotal = 0;
   double totalBill = 0;
   double tipPercent = 0;

   // *** Your program goes here ***
   printf("Enter amount of the bill: $");
   scanf("%lf", &costTotal);
   printf("\n");

   // *** processing ***
   taxTotal = 0.07 * costTotal;
   totalBill = costTotal + taxTotal;
   tipPercent = 0.15 * totalBill;
   totalBill = taxTotal + costTotal + tipPercent;

   // *** output ***

   printf("Based on a bill of $%.2lf, The calculated amounts are:\n", costTotal);
   printf("Tip = $%.2lf\n", tipPercent);
   printf("Tax = $%.2lf\n", taxTotal);
   printf("Total = $%.2lf\n", totalBill);
   printf("\n");

  }

void minutes_hours_delays()
{
   // Constant and Variable Declarations
   int numSeconds = 0;
   double numMins = 0.0;
   double numHours = 0.0;
   double numDays = 0.0;
   int const NUMSECMIN = 60;
   int const NUMSECHOUR = 3600;
   int const NUMSECDAY = 86400;

   // *** Your program goes here ***
   printf("Enter the number of seconds: ");
   scanf("%d", &numSeconds);
   printf("\n");
  
   // ***processing***
   numMins = numSeconds / NUMSECMIN;
   numHours = numSeconds / NUMSECHOUR;
   numDays = numSeconds / NUMSECDAY;

   if (numSeconds >= 1) {
       printf("The number of seconds you entered, %d, is %.2lf minutes.\n", numSeconds, numMins);
      
   }
   else {
       printf("The number of seconds entered must be greater than 0.\n");
   }
       if (numSeconds >= NUMSECHOUR) {
       printf("The number of seconds you entered, %d, is %.2lf hours.\n", numSeconds, numHours);
      
       }
       if (numSeconds >= NUMSECDAY) {
           printf("The number of seconds you entered, %d, is %.2lf days.\n", numSeconds, numDays);
      
       }
       printf("\n");

   }

void Calories_burned()
{
   // Constant and Variable Declarations
   const double CALORIES_MIN = 3.9;
   int loopStart = 10;
   int loopEnd = 30;
   double whileLoop = 19.5;
   int loopTwostart = 10;
   int loopTwoend = 30;
   double doWhileloop = 19.5;
   int loopForstart = 10;
   int loopForEnd = 30;
   double loopFor = 19.5;

   // *** Your program goes here ***
   printf("You burn 3.90 calories every minute you run.\n");//printing out the starting prompt no input
   printf("This shows how many calories you burn if you ran for 'x' minutes.\n");
  
   printf("\tMinutes Calories\n");
   printf("\t------- --------\n");
   printf("Using a while loop\n");
   while (loopStart <= loopEnd) {
       whileLoop = whileLoop + 19.5;//incrimenting the min loop varaiable
       printf("\t %d\t%.2lf\n", loopStart, whileLoop);
       loopStart = loopStart + 5;// incrimenting the caloires
   }
   printf("\n");// new line
   printf("Using a do-while loop\n");
   do {
       doWhileloop = doWhileloop + 19.5;//incrimenting the min loop varaiable
       printf("\t %d\t%.2lf\n", loopTwostart, doWhileloop);
       loopTwostart = loopTwostart + 5;// incrimenting the caloires
   } while (loopTwostart <= loopTwoend);// this is the condition
   printf("\n");
   printf("Using a for loop\n");
  
   for (int i = loopForstart; i <= loopForEnd; i = i + 5) {
       loopFor = loopFor + 19.5;
       printf("\t %d\t%.2lf\n", loopForstart, loopFor);
       loopForstart = loopForstart + 5;
   }
       printf("\n");

  
}

so then you can make a common main for all these functions and call these functions as below

int main(){

tip_tax_total();

minutes_hours_delays();

Calories_burned();

return 0;

}

Or you can even provide arguments to the above functions and then pass all the entered by the user and hence call the function alongwith passing those arguments .
