（问）将文件分成一些文件 [英] (ask) divide file into some file

问题描述

所以在这里，我真的不知道如何编程



这里的问题：



我有一个文件.txt格式，其中有许多数字顺序关闭。

例如：

+1

+2

+3

+4

+5

等......



例如：我的数据有100个数字下降，我必须将它们分成10个部分。之后该文件变为10文件.txt格式，其中有1 - 10（第一部分），11 - 20（第二部分），21 - 30等......


，程序必须用C ++编写。感谢您的帮助

解决方案

我在C中编码，

 #include <   stdio.h  >  
 #include < span class =code-keyword><   stdlib.h  >  
 #include <   string.h  >  
 
 int main（int argc，char ** argv）{
 int i，j; 
 char filename [6]，context [10]; 
 strcpy（filename，0.txt）; 
 freopen（input.txt，r，stdin）; 
 for（i = 0; i <   10;     i ++）{  
   
                                   filename [0]     ='  0'  + i;   
   
                                   freopen（filename， w，stdout）;   
   
                                   for（j   =   0;   j< 10;     j ++）{  
   
                                < span class =code-attribute>                   scanf（％s，context）;   
   
                                                  < span class =code-attribute> context [strlen（context）]     ='  \ n' ;   
   
                                        < span class =code-attribute>           printf（％s，context）;   
   
            < span class =code-attribute>                      }   
   
      < span class =code-attribute>            }   
   
                   return     0;   
   
  }  

C ++是一样的。

so here it is, I really dont know how to program

here the problem :

I have a file .txt format, in which there are many number sequentially down.
for example :
+1
+2
+3
+4
+5
etc...

eg: my data have 100 number down, I have to divide them into 10 parts. later the file become 10 file .txt format, in which there are number 1 - 10 (part one), 11 - 20 (part two), 21 - 30, etc ...

and the program must be made from C++. Thanks for help

解决方案

I code it in C,

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

int main(int argc, char** argv){
        int i,j;
        char filename[6],context[10];
        strcpy(filename, "0.txt");
        freopen("input.txt","r",stdin);
        for(i=0; i<10; i++){

                filename[0] = '0'+i;

                freopen(filename,"w",stdout);

                for(j=0; j<10; j++){

                        scanf("%s",context);

                        context[strlen(context)] = '\n';

                        printf("%s",context);

                }

        }

        return 0;

}

C++ is the same.
