C Language: 请大家帮我看下我做对了没有 [已解决]

蜡笔小烦

1. /*
   
2. Write a C program that declare one pointer type integer.
   
3. The pointer must points to a variable type integer.
   
4. Do not forget to give a value to the variable.
   
5. Then, print the output.
   
6. The output supposed to be just like the example below.
   
7. 
   
8. *************************************************************************************
   
9. e.g.
   
10. 
    
11. The value for [put variable_name here] is = ???
    
12. The value for [put pointer_name here] is = ???
    
13. The value that [put pointer_name here] point to is = ???
    
14. The memory address for [put variable_name here] is = ???
    
15. The memory address for [put pointer_name here] is = ???
    
16. 
    
17. *************************************************************************************
    
18. 
    
19. ??? : are based on the value that u gave to the variable/based on your compiler
    
20. */
    
21. 
    
22. #include
    
23. void main()
    
24. {
    
25. int year=100;
    
26. int *pointer_to_year=NULL;
    
27. 
    
28. pointer_to_year=&year;
    
29. 
    
30. printf("The value for year is = %d.\n",year);
    
31. printf("The value for pointer_to_year is = %d.\n",pointer_to_year);
    
32. printf("The value that pointer_to_year points to is = %d.\n",*pointer_to_year);
    
33. printf("The memory address for year is = %d.\n",&year);
    
34. printf("The memory address for pointer_to_year is = %d.\n",&pointer_to_year);
    
35. }

复制代码

我不是很确定
请大家帮我看一下
谢谢！

#include <iostream.h>
int main()
{
int year=100;
int *pointer_to_year;

printf("The memory address for pointer_to_year is = %d.\n",&pointer_to_year);


return 0;

不都一样吗？
除了这个<iostream.h>
什么分别呢？

你的code有没有拿去compile?

iostream 用 printf？

#include <stdio.h> 吧？

iostream应该是C++的吧？

其实c 与 c++ 的分别不在于 iostream 与 stdio.h ， 他们只是header file 罢了， c++ 可以用 iostream， 也可以用cstdio。

重要的是 syntax， 如 int function() 在c++ 是没有 argument， 在c 是可以接受任何的parameter。
