的fscanf [英] fscanf
问题描述
我做错了，我所知道的就是转向clc。我有一个
文本文件，其中包含由标签分隔的2个双打。
..26 0
是文本。我想阅读两个double并将它们打印出来。这是我的
档。
#include< stdio.h>
int main（ ）{
FILE * fp;
double x，y;
fp = fopen（" zo"，" r"）; / *错误检查简洁* /
fscanf（fp，"％。2f \t％。2f"，& string）;
fclose（fp ）;
printf（"％。2f％.2f"，x，y）;
}
所有我get是包含在x和y中的垃圾。对于任何简单的
理由，我显然无法阅读并打印出来自
这个文本文件的stdin。我不认为恐惧是非常必要的。

I''m doing something wrong and all I know to do is turn to clc. I have a
text file containing 2 doubles separated by a tab.
..26 0
Is the text. I want to read the two double and printf them out. Here''s my
file.
#include <stdio.h>
int main() {
FILE *fp;
double x,y;
fp=fopen("zo","r"); /*error checking out for brevity */
fscanf(fp,"%.2f\t%.2f",&string);
fclose(fp);
printf("%.2f%.2f",x,y);
}
All I get is garbage that is contained in x and y. For whatever simple
reason that is beyond me evidently I can''t read and printf out to stdin from
this text file. I don''t think fread is really necessary.

你是个骗子，比尔。该代码无法编译，因此您无法获得执行此程序的任何内容。
You''re a liar, Bill. That code does not compile, so it''s impossible
for you to get anything out of executing this program.

请发布用于编译和生成导致垃圾打印的
可执行文件的* actual *代码。您发布的代码将无法编译。

<snipped code>
Please post the *actual* code that you used to compile and generate the
executable that caused garbage to be printed. The code you posted will
not compile.

好的，我确实写了这个。我将再次查看实际代码。

Ok I did write this on the fly. I will look again at the actual code.
