A liter is 0.264179 gallons. Write a
- Include required header files.
- Declare and initialize a constant value “lpg = 0.264179”.
- Define a function named “calc()” to calculate “milage”.
- Declare a variable “gal”.
- Compute “gal” and “milage”
- Function to return “milage”.
- Define a “main()” function.
- Declare the variables “lit” and “miles”.
- Declare a variable “ch”.
- “do… while” loop to get the user input repeatedly.
- Get the “lit” and “miles” from the user.
- Call “calc()” with an arguments “lit” and “miles” values and print the “milage”.
- Get the user input to repeat the program or not.
- The input is checked with the condition and repeat or exit the program.
Explanation of Solution
Program to compute number of miles per gallon the car delivered:
// Include required header files
#include <iostream>
using namespace std;
// Assign const value
float const lpg=0.264179;
// Function definition of calc()
float calc(float liters, float miles)
{
// Declare gal
float gal;
// Compute gal
gal = lpg * liters;
// Compute milage
float milage = miles/gal;
// Return milage
return(milage);
}
// Function definition of main()
int main()
{
// Declare lit and miles
float lit, miles;
// Declare ch
char ch;
// do... while loop
do{
// Get the liters
cout<<"\nEnter the number of liters of gasoline: ";
// Assign the user input to lit
cin>>lit;
// Get the miles
cout<<"\nEnter the number of miles Travelled: ";
// Assign the user input to miles
cin>>miles;
// Display the miles per gallon the car delivered
cout<<"\nNumber of miles per gallon the car delivered: ";
// Call the function cal() and return the result
cout<< calc(lit, miles) << endl;
// Get the user input
cout<<"\nDo you want to repeat(y/n)??: ";
// Assign the user input to ch
cin>>ch;
// While loop condition to check ch is equal to y
}while(ch=='y' || ch=='Y');
// Return 0
return 0;
}
Enter the number of liters of gasoline: 5
Enter the number of miles Travelled: 30
Number of miles per gallon the car delivered: 22.7119
Do you want to repeat(y/n)??: n
