若有以下程序void f(int n);main(){ void f(int n);f(5);}void f(int n){ printf("%d\n",n); }则以下叙述中不正确的是
A. 若只在主函数中对函数f进行说明,则只能在主函数中正确调用函数f
B. 若在主函数前对函数f进行说明,则在主函数和其后的其它函数中都可以正确调用函数f
C. 对于以上程序,编译时系统会提示出错信息:提示对f函数重复说明
D. 函数f无返回值,所以可用void将其类型定义为无值型
下面程序输出的结果是 【 】#define MAX 3int a[MAX];main(){ fun1( ); fun2( a ); printf("\n");}fun1( ){ int k, t=0;for (k=0;k
