下面的程序各自独立，请问执行下面的四个TestMemory 函数各有什么样的结果?①void GetMemory(char * p){p = (char * )malloc(100);}void TestMemory (void){char *str = NULL;GetMemory (str);strcpy(str, "hello world");prinff(str);}② char * GetMemory (void){char p[ ] = "hello world";return p;}void TestMemory (void){char * str = NULL;str = GetMemory( );printf(str);}③void GetMemory(char * * p, int num){* p = (char * )malloc(num);}void TestMemory (void){char * str = NULL;GetMemory(str, 100);strcpy( str, "hello" );printf(sir);}④void TestMemory (void){char *str = (char * )malloe(100);strepy (str, "hello" );free ( str );if(str ! = NULL){strepy( str, "world" );printf(str);}}

}
void TestMemory (void)
{
char *str = NULL;
GetMemory (str);
strcpy(str, "hello world");

② char * GetMemory (void)
{
char p[ ] = "hello world";
return p;
}
void TestMemory (void)
