Classwork_3.3: Correct the program below that will read two numbers: number of drinks and number of sandwiches, and display the total bill calculated as: Total bill = Number of Drinks X 5.50 + Number of Sandwiches X 10.00 Answer the questions below. C-Program with error: Write the correct program here: #include<stdio.h> int main (void) floats numberofDrinks, numberofSandwiches; float totalBilling: printf("Enter number of Drinks \n"); scanf("%d",&numberofdrinks); printf("Enter number of Sandwiches\n") scanf("%f",&numberofSandwiches); totalbilling = numberofDrinks *5.50 + numberofsandwiches/10.00; printf("Total bill = %f\n",totalBilling); return 0; Insert the correct output here: 1. Find the instruction in the program with the following errors: a. Syntax error b. Logic Error C. Run time error 2. Is there a run-time error in the classwork 4 program? (Yes/No) Prepared by: Dr. Hussein Abdul Rahman & Mr. Michael Obenque

Answer 1

Answer:

The given program is as follows. (I will mark the errors in Bold)

#include<stdio.h>
int main(void)
{
   floats numberofDrinks,numberofSandwiches; /* syntax error, because floats is not data type. It should be float */
   float totalBilling: /*syntax error, Every statement is ending in semicolon (;) but not in colon (:) */
   printf("Enter number of Drinks\n");
   scanf("%d",&numberofdrinks); /* syntax error, written as numberofdrinks instead of numberofDrinks, run time error, the format specifier should be %f instead of %d */
   printf("Enter number of Sandwiches\n");
   scanf("%f",&numberofSandwiches);
   totalbilling=numberofDrinks*5.50 + numberofsandwiches/10.00; /* syntax error, written as totalbilling instead of totalBilling, syntax error, written as numberofsandwiches instead of numberofSandwiches,

logic error, numberofSandwiches/10.0 instead of numberofSandwiches*10.0 */
   printf("Totalbill=%f\n",totalBilling);
   return 0;
}

Correct Program:

#include<stdio.h>
int main(void)
{
   float numberofDrinks,numberofSandwiches;
   float totalBilling;
   printf("Enter number of Drinks\n");
   scanf("%f",&numberofDrinks);
   printf("Enter number of Sandwiches\n");
   scanf("%f",&numberofSandwiches);
   totalBilling=numberofDrinks*5.50 + numberofSandwiches*10.00;
   printf("Total bill=%f\n",totalBilling);
   return 0;
}

Output:
