调用在当前函数下声明的函数(Calling a function which is declared under the current function)

 我是C的新手，在尝试调用在当前函数Ex下声明的函数时遇到问题： 
 
void test (){ test1 ();}
void test1(){ }
 
 我可以将test1移到测试之上，但我也有这个： 
 
void test () {test1 ()}
void test4 () {test ()}
void test3 () {test4 ()}
void test1 () {test3 ()}
 
 所以你看到如果我移动test（）我会对test4（）有同样的问题吗？ 我能做什么 ？ 
 
 谢谢 

I'm a newcomer to C and I have a problem when trying to call a function which is declared under the current function Ex:
 
void test (){ test1 ();}
void test1(){ }
 
I could just move test1 above test, but I have this as well :
 
void test () {test1 ()}
void test4 () {test ()}
void test3 () {test4 ()}
void test1 () {test3 ()}
 
So do you see that If I moved test() I will have the same problem for test4 () ? What could I do ?
 
Thanks
