程式码好歹也缩缩排吧？= =a
#include <iostream>
using namespace std;
int main()
{
char *s3,*s5;
s3 =
(char*)malloc(10 * sizeof(char));
strcpy(s3,"Welcome");
s5 =
(char*)malloc(15 * sizeof(char));
strcpy(s5,"Good morning");
cout<<"first s3="<<s3<<endl;
cout<<"first s5="<<s5<<endl;
s3 = s5;
cout<<"second s3="<<s3<<endl;
cout<<"second s5="<<s5<<endl;
printf("second s3=%s\n",s3);
printf("second s5=%s\n",s5);
strcpy(s5,"123");
cout<<"third s3="<<s3<<endl;
cout<<"third s5="<<s5<<endl;
// 动态配置出来的记忆体
// 用完请记得释放
free(s3);
free(s5);
system("pause");
return 0;
}
