I am new at this but I think I may have it. This is the assignment:
The program should ask for the Customers First Name and Last Name (Use Initials only for now)
-Use 2 different variables, one for the first name and one for the last
The program should ask for the prices of 5 different items
-Use 5 different input statements and 5 different variables
The program should add the 5 products together giving the subtotal price.
Find the Tax by multiplying the Subtotal by a Constant called TaxRate
For the Total, add the Tax to the subtotal
Output the First initial, a period and space, last initial, a period and space, a message to the user and the total
Example:
Please enter First initial
Please enter Last initial
Please enter cost of Item1
Please enter cost of Item2
Please enter cost of Item3
Please enter cost of Item4
Please enter cost of Item5
SubTotal = Item1 + Item2 + Item3 + Item4 + Item5
Tax = SubTotal * TaxRate
Total = SubTotal + Tax
OutPut=
B. S.
Your total cost is:Here is my code:
include <stdio.h>
#define TaxRate 10.0f
/* global variable*/
char firstname[20];
char lastname[20];
float Tax;
float st;
float Item1,Item2,Item3,Item4,Item5;
float total;
/*functions protypes*/
void enterItemPrice(void);
void getUserName(void);
float subTotal(void);
float calculatetax(void);
float totalprice(void);
void output(void);
int main(void)
{
getUserName();
enterItemPrice();
st = subTotal();
calculatetax();
totalprice();
output();
return 0;
}
void getUserName(void)
{
printf("Enter your first name:");
scanf("%s", firstname);
printf("\nEnter your last name:");
scanf("%s", lastname);
}
void enterItemPrice(void)
{
printf("\nEnter price of item1:");
scanf("%f", &Item1);
printf("\nEnter price of item2:");
scanf("%f", &Item2);
printf("\nEnter price of item3:");
scanf("%f", &Item3);
printf("\nEnter price of item4:");
scanf("%f", &Item4);
printf("\nEnter price of item5:");
scanf("%f", &Item5);
}
float subTotal(void)
{
float localst;
localst = Item1 + Item2 + Item3 + Item4;
return localst;
}
float calculatetax(void)
{
Tax = st * TaxRate;
}
float totalprice(void)
{
total= Tax + st;
}
void output(void)
{
printf("the costumer's first name is %s", firstname);
printf("\nthe costumer's last name is %s", lastname);
printf("\nThe price of the first item is %f", Item1);
printf("\nThe price of the first item is %f", Item2);
printf("\nThe price of the first item is %f", Item3);
printf("\nThe price of the first item is %f", Item4);
printf("\nThe price of the first item is %f", Item5);
printf("\nthe subtotal is %f", st);
printf("\nthe taxable price is %f", Tax);
printf("\n the total price is %f", total);
}
