用如下代码向某个文件写如一个字符为什么提示内存无法被写入？？
#include<stdio.h>
#include<stdlib.h>
void main()
{
     FILE*fp;
     char ch='a';
     if(fopen("name.c","w")==NULL)
     exit(0);
     printf("%d",fopen("name.c","w"));
     fputc(ch,fp);
     fclose(fp);
     }

为什么#include<stdio.h>
#include<stdlib.h>
void main()
{
     FILE*fp;
     char ch='a';
     fp=fopen("abc.txt","w");
     if(fp==NULL)
     exit(0);
     printf("%d",fopen("name.c","w"));
     fputc(ch,fp);
     fclose(fp);
     }可以而
#include<stdio.h>
#include<stdlib.h>
void main()
{
     FILE*fp;
     char ch='a';
     if(fp=fopen("abc.txt","w")==NULL)
     exit(0);
     printf("%d",fopen("name.c","w"));
     fputc(ch,fp);
     fclose(fp);
     }就不可以

我抄错了就算改过来也是不行的
