如何创建一个循环来在C中的函数菜单之间切换？

#include <stdio.h>

void displayMenu() {
    printf("1. Option 1\n");
    printf("2. Option 2\n");
    printf("3. Option 3\n");
    printf("4. Exit\n");
}

void option1() {
    printf("You selected Option 1.\n");
}

void option2() {
    printf("You selected Option 2.\n");
}

void option3() {
    printf("You selected Option 3.\n");
}

int main() {
    int choice;
    
    while (1) {
        displayMenu();
        
        printf("Enter your choice: ");
        scanf("%d", &choice);
        
        switch (choice) {
            case 1:
                option1();
                break;
            case 2:
                option2();
                break;
            case 3:
                option3();
                break;
            case 4:
                printf("Exiting...\n");
                return 0;
            default:
                printf("Invalid choice. Please try again.\n");
                break;
        }
    }
    
    return 0;
}
