Question

*In C language

*Without using Strings

Write a program that uses a for loop to calculate the average cost of a dinner for a group of 10 people. Your program will use a function that will ask the user to enter in the price of each meal and return the value entered. Your program will calculate the total due for all 10 meals, the total tip using a defined constant of 20%, and the average price of a dinner. You program will then use a function to display the total due for the meals, the total tip using a defined constant of 20%, and the average price of a dinner.

SOLUTION-

I have solved the same problem . Below i have given the code and scrrenshot!

C CODE-

//------------C CODE------------
#include <stdio.h> //Header file
//function to get the price of meals
double Price ()
{
double rate;
printf ("Enter the price of meal :");
scanf ("%lf", &rate); // user will enter the price
return rate;
}

void display (double Due, double tip, double average) //To display the average tip, and total
{
printf ("Total Due : %lf\n", Due);
printf ("Total tip : %lf\n", tip);
printf ("Average price of dinner : %lf\n", average);
}

int main ()
{
double rate[10], Due = 0, tip = 0, average = 0;   //Declaration
for (int i = 0; i < 10; i++)    //To calculate total price
    {
      rate[i] = Price ();
    }
for (int i = 0; i < 10; i++)     //To calculate total Due
    {
      Due = Due + rate[i];
    }
tip = 0.2 * Due;               //Tip for meals
average = Due / 10.0;         //average
display (Due, tip, average);  
return 0;
}
