How to call functions in C language:

1. The most common is to call directly

void fun(void) { ...... //你的代码 ..... } { ....... fun(); ..... }

2.Use function pointer

void fun(void) { printf("OK!\n"); } int main(void) { void (*pfun)(); pfun=fun; (*pfun)(); return 0; }

3. Function parameter method

void fun(void) { printf("OK!\n"); } { CallFun(fun);

In summary, there are three main methods of calling functions in C language: direct calling, function pointer calling, and function pointer passing calling. The latter two are essentially the same, but there are slight differences in whether there is a return value.
