[英]C - Terminal Write and Output to a Text File
I am a student taking an introductory C course and have our first C midterm coming up.我是一名参加 C 入门课程的学生,我们的第一个 C 期中考试即将到来。 Our test environment would store our actions and printf output to a text file.我们的测试环境会将我们的操作和 printf 输出存储到一个文本文件中。 However, our TA suggested we write to a file ourselves using fprintf just in-case.但是,我们的助教建议我们自己使用fprintf写入文件以防万一。
Is there a very simple way I can copy my terminal/console output and input (what I enter in after scanf ) to a text file like output.txt?有没有一种非常简单的方法可以将我的终端/控制台输出和输入(我在scanf之后输入的内容)复制到像 output.txt 这样的文本文件中?
I tried我试过
freopen("output.txt","w",stdout); freopen("output.txt","w",stdout);
but that won't write my scanf input to the text file.但这不会将我的 scanf 输入写入文本文件。
Can anyone help?任何人都可以帮忙吗?
Don't use scanf();不要使用 scanf(); Use fgets();使用 fgets(); An example:一个例子:
#include <stdio.h>
#include <stdlib.h>
#define Contents_Size 1000
int main()
{
char contents[Contents_Size];
//Opening the file
FILE * fp;
fp = fopen("\myfile.txt", "w"); //"w" = write
//If there is an error
if(fp == NULL)
{
//Exit
printf("Error!\n");
exit(EXIT_FAILURE);
}
//This part require your input
printf("Enter the contents of file: \n");
fgets(contents, Contents_Size, stdin);
//Write your input in file
fputs(contents, fp);
//Close the file
fclose(fp);
return 0;
}
fgest() will copy your input in contents[] and fputs() will paste every char of contents[] in your file. fgest() 将复制您在内容 [] 中的输入,而 fputs() 会将内容 [] 的每个字符粘贴到您的文件中。
