C 函数指针既不是函数也不是指针

C 函数指针的独特本质

c
#include 
int add(int a, int b) {
    return a + b;
}
int multiply(int a, int b) {
    return a * b;
}
int main() {
    int result;
    int (*operation)(int, int);  // 定义函数指针
    operation = add;  // 将函数指针指向加法函数
    result = operation(3, 4);
    printf("Addition result: %d%
", result);
    operation = multiply;  // 将函数指针指向乘法函数
    result = operation(3, 4);
    printf("Multiplication result: %d%
", result);
    return 0;
}
