#include "stdio.h"
void main ()
{
    FILE *fp;
    char str[100];
    gets(str);
    fopen("d:\\test.txt","w");
    fputs(str,fp);
    fclose(fp);

}
不知道是哪里不对  

虽然没有分还是说下，fp= fopen("d:\\test.txt","w");

谢谢

#include "stdio.h"

    char str[100];
    gets(str);
    fopen("d:\\test.txt","w"); ----------->这个地方改下 fp=fopen("d:test.txt","w")
    fputs(str,fp);
    fclose(fp);

}
