Project 2 - Implement the Code for controlling the retraction and extension of Airplane’s landing gear
Program
#include
// Enum to represent the landing gear status
enum LandingGearStatus {
RETRACTED,
EXTENDED
};
// Structure to represent the airplane
struct Airplane {
enum LandingGearStatus landing_gear_status;
};
// Function to retract the landing gear
void retract_landing_gear(struct Airplane *airplane) {
if (airplane->landing_gear_status == RETRACTED) {
printf("Landing gear is already retracted.\n");
} else {
printf("Retracting landing gear...\n");
airplane->landing_gear_status = RETRACTED;
printf("Landing gear retracted.\n");
}
}
// Function to extend the landing gear
void extend_landing_gear(struct Airplane *airplane) {
if (airplane->landing_gear_status == EXTENDED) {
printf("Landing gear is already extended.\n");
} else {
printf("Extending landing gear...\n");
airplane->landing_gear_status = EXTENDED;
printf("Landing gear extended.\n");
}
}
int main() {
// Create an instance of the Airplane structure
struct Airplane airplane;
airplane.landing_gear_status = RETRACTED;
while (1) {
// User menu
printf("\nAirplane's Landing Gear Control:\n");
printf("1. Retract Landing Gear\n");
printf("2. Extend Landing Gear\n");
printf("3. Quit\n");
// User input
int choice;
printf("Enter your choice (1/2/3): ");
scanf("%d", &choice);
// Perform action based on user choice
switch (choice) {
case 1:
retract_landing_gear(&airplane);
break;
case 2:
extend_landing_gear(&airplane);
break;
case 3:
printf("Exiting program.\n");
return 0;
default:
printf("Invalid choice. Please enter 1, 2, or 3.\n");
}
}
return 0;
}
Expected Output
Airplane's Landing Gear Control:
1. Retract Landing Gear
2. Extend Landing Gear
3. Quit
Enter your choice (1/2/3): 1
Retracting landing gear...
Landing gear retracted.
Airplane's Landing Gear Control:
1. Retract Landing Gear
2. Extend Landing Gear
3. Quit
Enter your choice (1/2/3): 2
Extending landing gear...
Landing gear extended.
Airplane's Landing Gear Control:
1. Retract Landing Gear
2. Extend Landing Gear
3. Quit
Enter your choice (1/2/3): 1
Landing gear is already retracted.
Airplane's Landing Gear Control:
1. Retract Landing Gear
2. Extend Landing Gear
3. Quit
