在C中将算术运算符存储在数组中？

#include <stdio.h>

// 定义算术运算函数
int add(int a, int b) {
    return a + b;
}

int subtract(int a, int b) {
    return a - b;
}

int multiply(int a, int b) {
    return a * b;
}

int divide(int a, int b) {
    if (b == 0) {
        printf("Error: Division by zero\n");
        return 0;
    }
    return a / b;
}

int main() {
    // 定义函数指针数组
    int (*operations[])(int, int) = {add, subtract, multiply, divide};

    int a = 10, b = 5;
    int choice;

    printf("Enter operation (0: add, 1: subtract, 2: multiply, 3: divide): ");
    scanf("%d", &choice);

    if (choice >= 0 && choice < 4) {
        int result = operations[choice](a, b);
        printf("Result: %d\n", result);
    } else {
        printf("Invalid choice\n");
    }

    return 0;
}
