使用C在Ubuntu中创建文件

Create file using C in Ubuntu. I've tried that code and it doesn't work.

在Ubuntu中使用C创建文件。我已经尝试过该代码,但它不起作用。

#include<stdio.h> 
#include<string.h>
int main() 
{ 
  char a[50];
  char command[150];
  printf("Enter The File's Name");
  gets(a);
  strcpy("touch ");
  strcat("a");
  system(command);
  return 0;
}

3 个解决方案

#1

Your strcpy should be strcpy(command, "touch") and your strcat should be strcat(command, a)

你的strcpy应该是strcpy(命令,“触摸”),你的strcat应该是strcat(命令,a)

But there are much better ways to create an empty file...

但是有更好的方法来创建一个空文件......

#2

You forgot to pass command to strcpy and strcat.

你忘了将命令传递给strcpy和strcat。

You are using the string "a" in the call to strcat instead of the variable a.

您在调用strcat而不是变量a时使用字符串“a”。

Replace

  strcpy("touch ");
  strcat("a");

  strcpy(command, "touch ");
  strcat(command, a);

#3

I think you were trying to do the code in this way, though as Jeff told you it is not the best way to create a file-

我认为你试图以这种方式编写代码,尽管Jeff告诉你这不是创建文件的最佳方式 -

#include <stdio.h>
#include <stdlib.h>

int main()
{
   char a[50],command[150];
   printf("Enter the file name: ");
   gets(a);
   sprintf(command,"touch %s",a);
   system(command);
   return 0;
}
