如何在C中实现动态调度表

#include<stdio.h>

void f1() {
    printf("Function 1\n");
}

void f2() {
    printf("Function 2\n");
}

void f3() {
    printf("Function 3\n");
}

int main() {
    void (*dispatch_table[])() = {f1, f2, f3};
    int index = 1;
    dispatch_table[index]();
    return 0;
}

#include<stdio.h>

void f1() {
    printf("Function 1\n");
}

void f2() {
    printf("Function 2\n");
}

void f3() {
    printf("Function 3\n");
}

int main() {
    int index = 1;
    switch (index) {
        case 0:
            f1();
            break;
        case 1:
            f2();
            break;
        case 2:
            f3();
            break;
        default:
            printf("Invalid index\n");
            break;
    }
    return 0;
}

#include<stdio.h>

void f1() {
    printf("Function 1\n");
}

void f2() {
    printf("Function 2\n");
}

void f3() {
    printf("Function 3\n");
}

int main() {
    int index = 1;
    if (index == 0) {
        f1();
    } else if (index == 1) {
        f2();
    } else if (index == 2) {
        f3();
    } else {
        printf("Invalid index\n");
    }
    return 0;
}
