如何将文本打印到文件？ C ++ [英] How Do I Print Text To A File? C++

问题描述

嗨我有一个问题，当我尝试写一个.txt文件我得到这个：

>错误期望FILE之前的初始化程序和错误预期的构造函数，解构函数，或者之前键入转换（令牌



i试图将其排除在函数之外但是存在相同的错误< br $>




int printname（）

FILE * f

f = fopen（ name.txt，r）;

fprintf（f，歌曲：％s \ n，文件名）;`



我该怎么办？

Hi i have a problem when i try to write a .txt file i get this:
> error expected initializer before FILE and error expected constructor, deconstructor, or type the conversion before ( token

i tried to put it out of the function but there is the same error


int printname()
FILE *f
f = fopen ("name.txt", "r");
fprintf(f, "Song :%s\n", filename);`

what can i do?

推荐答案

你的解决方案：学习语言！

当然我可以给你一个有效的代码但是它几乎涉及重写所有这些代码。这将使它成为一个神奇的解决方案。

我看到你几乎不知道该语言的语法。这段代码有更多的错误。



所以我的建议对你来说会更有成效：

- 阅读文档，手册，书籍......

- Google是你的朋友。

- 按照教程，你可以找到关于任何方面的教程语言。

- 滥用调试器看你的代码是否正在运行以及每次出现运行时错误。



没有捷径知识，不要跳过步骤。

编程是细节的艺术，掌握这门艺术需要时间。

Your solution: Learn the language !
Sure I could have give you a working code but it almost involve rewriting all this code. It would make it a magic solution.
I see that you barely know the syntax of the language. There is more errors that lines is this piece of code.

So I have an advice that will be more productive for you:
- read documentation, manuals, books ...
- Google is your friend.
- follow tutorials, you can find tutorials about any aspect of the language.
- Abuse of debugger to see your code running and every time you get a runtime error.

There is not short cut to knowledge, don't skip steps.
Programming is the art of details, and it takes time to master this art.
