Question

我的原始代码用于读取和复制一个文件到另一个文件（内容包含几个段落，每个段落用换行符分隔）。但现在我需要读取文件并将其写入几个不同的文件（每个文件只包含一个段落）。但我不知道该怎么做，希望任何人都可以帮忙。原始代码如下所示

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


int main(void) {
setvbuf(stdout, NULL, _IONBF, 0);
setvbuf(stderr, NULL, _IONBF, 0);
char ch, file_name[10];

FILE *fp;
FILE *fa;

printf("enter the name of file\n");
gets(file_name);
fa=fopen("write.txt","w");
fp=fopen(file_name,"r");

if(fp==NULL)
{
    perror("error while opening the file. \n");
    exit(1);
}

printf("the contents of %s file are :\n", file_name);
while((ch=fgetc(fp))!=EOF){
    printf("%c",ch);
    fprintf(fa,"%c",ch);

}



fclose(fa);
fclose(fp);
return 0;

}

        }

        c:

                                    }
                    }
                }

         d:

                }

    fclose(fa);
    fclose(fp);
    fclose(fc);

    return 0;
}

如何根据不同的段落读取文件并写入不同的文件
