Question

roblem 8 and 9 refer to the following description. A shipping company uses the following function to calculate the cost in dollars) of shipping based on the weight of the package (in pounds). c(w) = 2.48w, 0 <w<15 2.36w, 15 Sw< 45 2.24w, 45 Sw<75 2.12w, 75 Sw<90 Requirement for both problems: • If the weight is greater than 90, display a message the package cannot be shipped." . When the shipping cost is display, include the symbol (S) and 2 digits after the decimal point. • Show Output case when w= 10, 20, 50,80 5.90 8. (10 points) Use if else if structure. Write a program that prompt the user to enter the weight of the package and display the shipping cost. Consider all real numbers of weight values including negative.

C++

Answer 1

CODE:

#include <iostream>

using namespace std;

int main()
{
//create two variables one to store the weight and other for calculating the shipping cost
float weight, shippingCost=0;
//ask how much is the weight
cout<<"How much weight is the package?";
//get teh weight
cin>>weight;
/*
check for the boundary conditions.
If it is greater than or equal to 90 then print package cannot be shipped
*/
if(weight >=90)
cout<<"\nThe package cannot be shipped";
//if the weight is less than 0 then given wrong input
else if(weight<0)
cout<<"\nGiven wrong weight. Please try again.";
  
/***********start checking for the functions*************/
  
//if weight is between 0 and 15 then get the appropriate function
else if(weight>=0 && weight<15)
{
//multiply with the correct weight and store it as shipping cost
shippingCost = 2.48*weight;
//printing the shipping cost with 2 decimal precision
printf("\nShipping cost is: $%.2f",shippingCost);
}
  
//if weight is between 15 and 45 then get the appropriate function
else if(weight>=15 && weight<45)
{
//multiply with the correct weight and store it as shipping cost
shippingCost = 2.36*weight;
//printing the shipping cost with 2 decimal precision
printf("\nShipping cost is: $%.2f",shippingCost);
}
  
//if weight is between 45 and 75 then get the appropriate function
else if(weight>=45 && weight<75)
{
//multiply with the correct weight and store it as shipping cost
shippingCost = 2.24*weight;
//printing the shipping cost with 2 decimal precision
printf("\nShipping cost is: $%.2f",shippingCost);
}
  
//if weight is between 75 and 90 then get the appropriate function
else if(weight>=75 && weight<90)
{
//multiply with the correct weight and store it as shipping cost
shippingCost = 2.12*weight;
//printing the shipping cost with 2 decimal precision
printf("\nShipping cost is: $%.2f",shippingCost);
}
return 0;
}
