**Week 12 Programming Exercise**
### Program Overview
This program calculates the miles per gallon (mpg) based on user input for miles driven and gallons of gas used. It continues to prompt for these values until a user enters 0 for miles to end the program.
### Code
```c
start
Declarations
num miles
num gallons
num mpg
num END_VAL = 0
output "How many miles did you drive? Enter 0 to quit."
input miles
// This program continuously prompts a user for miles driven until 0 is entered.
// While miles are not 0, gallons are entered, and mpg is calculated.
if (miles not END_VAL)
{
output "How many gallons of gas did you use?"
input gallons
mpg = miles / gallons
output "Your mpg is" + mpg
}
else
{
output "End of program"
}
stop
```
### Explanation
- **Declarations**: Variables `miles`, `gallons`, `mpg`, and `END_VAL` are declared. `END_VAL` is initialized to 0.
- **Input Prompt**: The user is asked, "How many miles did you drive? Enter 0 to quit."
- **Loop Condition**: If `miles` is not equal to `END_VAL` (0), the user is then asked, "How many gallons of gas did you use?"
- **Calculation of mpg**: `mpg` is calculated as `miles / gallons`.
- **Output mpg**: The calculated miles per gallon is displayed.
- **End Condition**: If `miles` is 0, the program outputs "End of program" and stops.
### Development Environment Details
- Integrated Development Environment (IDE): Visual Studio
- Solution Explorer is open, showing the project structure.
- The active file in the editor is "Week 12 Programming Exercise.c" within the "Week 12 Programming Exercise" solution.
This exercise is suitable for understanding basic input/output operations in C and introduces simple conditionals for controlling program flow.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F0c0d8084-d214-45df-9fd7-cc0a72a17a23%2F21003816-125d-40f8-b276-af5168c24969%2F8hyf84q_processed.png&w=3840&q=75)
