笔试面试 对如下代码描述正确的是? void getMemory(char **p) { *p = (char*)malloc(100); } void test() { char * str = null; getMemory(&str); strcpy(str,"hello world"); printf(str); }
笔试面试 下面这段代码输出什么? package main import ( "fmt" "unicode/utf8" ) func main(){ s:="奇安信666" l1:=len(s) l2:=utf8.RuneCountInString(s) fmt.Println(l1) fmt.Println(l2) }
