概述
简单的C语言示例:
#include <stdio.h>
enum {
LED1,
LED2,
LED3,
LED_NUM
};
void Func_LED1(unsigned char state);
void Func_LED2(unsigned char state);
void Func_LED3(unsigned char state);
/**
* 函数指针数组定义格式
* 函数返回类型 (*指针变量名[数组大小])(函数参数列表);
* @param state
* @return
*
*/
void (*func[LED_NUM])(unsigned char state) = {Func_LED1, Func_LED2, Func_LED3};
void Func_LED1(unsigned char state)
{
if (state)
printf("LED1 ON\r\n");
else
printf("LED1 OFF\r\n");
}
void Func_LED2(unsigned char state)
{
if (state)
printf("LED2 ON\r\n");
else
printf("LED2 OFF\r\n");
}
void Func_LED3(unsigned char state)
{
if (state)
printf("LED3 ON\r\n");
else
printf("LED3 OFF\r\n");
}
int main() {
// for (int i = 0; i < LED_NUM; ++i) {
// func[i](1);
// }
func[LED1](1);
func[LED2](1);
func[LED3](1);
return 0;
}
运行结果:
