复制程序

写了一个复制程序……

 

#include <stdio.h>#include <stdlib.h>#include <string.h>#include <stddef.h>#include <Fatal.h>#define MAXSIZE 100#define OK 1#define ERROR 0int IsCorrect(char *[]);int main(int argc,char *argv[]){//此程序用于复制文本文件FILE *fp_old, *fp_new;char **p=argv+1;char str[MAXSIZE];if(argc!=3){FatalError("BAD INPUT--The incompleted path info...");exit(EXIT_FAILURE);}//ifif(IsCorrect(argv+1)==ERROR)exit(EXIT_FAILURE);fp_old=fopen(*p,"r");fp_new=fopen(*++p,"w");while(fgets(str,MAXSIZE,fp_old)!=NULL)fputs(str,fp_new);fclose(fp_new);fclose(fp_old);fputs("Copy completed!!",stdout);exit(EXIT_SUCCESS);}//mainint IsCorrect(char *path[]){//此子程序用于检查路径是否正确char **p=path;FILE *fp_old, *fp_new;char ch;char TmpArray[MAXSIZE];char *NewPath;size_t size;if((fp_old=fopen(*p,"r"))==NULL){//检查源文件是否存在perror(*p);return ERROR;}//iffclose(fp_old);if((fp_new=fopen(*++p,"r"))!=NULL){//检查与目标文件相关fclose(fp_new);printf("/nThe file %s exited!!/n",*p);puts("The operation candidated as followings .../n""1.Cancel copying/n""2.Cover the old file/n""3.Change the filename");ch=getchar();switch(ch){case '1':return ERROR;break;case '2':return OK;break;case '3':break;default:puts("ERROR CHOOSE!!");return ERROR;break;}//switchif((NewPath=calloc(MAXSIZE,sizeof(char)))==NULL){//重新开辟空间FatalError("Out of space!!!");exit(EXIT_FAILURE);}//if*(strrchr(*p,'//')+1)='/0';puts("Input the new name..");fflush(stdin);fgets(TmpArray,MAXSIZE,stdin);size=strlen(TmpArray);TmpArray[size-1]=TmpArray[size];strcat(strcat(NewPath,*p),TmpArray);*p=NewPath;}//ifreturn OK;}//IsCorrect

 

程序中的fatal.h是我自己定义的宏……开始写的不够好，只能复制文本文件。于是改了一下，有了下面的代码：

 

/*-----------------------------------*//*STATE：此程序用于复制所有类型的文件*//*-----------------------------------*/#include <stdio.h>#include <stdlib.h>#include <string.h>#include <Fatal.h>#define MAXSIZE 100#define OK 1#define ERROR 0int IsCorrect(char **);int main(int argc,char **argv){FILE *fp_old, *fp_new;char str[MAXSIZE];size_t readnum;if(argc!=3)FatalError("BAD INPUT--The incompleted path info...");if(IsCorrect(++argv)==ERROR)exit(EXIT_FAILURE);fp_old=fopen(*argv,"rb");fp_new=fopen(*++argv,"wb");while((readnum=fread(str,sizeof(char),MAXSIZE,fp_old))!=0)fwrite(str,sizeof(char),readnum,fp_new);fclose(fp_new);fclose(fp_old);fputs("Copy completed!!",stdout);exit(EXIT_SUCCESS);}int IsCorrect(char **path)//此子程序用于检查路径是否正确{FILE *fp_old, *fp_new;char ch;char TmpArray[MAXSIZE];char *NewPath;size_t size;if((fp_old=fopen(*path,"rb"))==NULL){//检查源文件是否存在perror(*path);return ERROR;}//iffclose(fp_old);if((fp_new=fopen(*++path,"rb"))!=NULL){//检查与目标文件相关fclose(fp_new);printf("/nThe file %s exited!!/n",*path);puts("The operation candidated as followings .../n""1.Cancel copying/n""2.Cover the old file/n""3.Change the filename");ch=getchar();switch(ch){case '1':return ERROR;break;case '2':return OK;break;case '3':break;default:puts("ERROR CHOOSE!!");return ERROR;break;}//switchif((NewPath=calloc(MAXSIZE,sizeof(char)))==NULL)//重新开辟空间FatalError("Out of space!!!");*(strrchr(*path,'//')+1)='/0';puts("Input the new name..");fflush(stdin);fgets(TmpArray,MAXSIZE,stdin);size=strlen(TmpArray);TmpArray[size-1]=TmpArray[size];strcat(strcat(NewPath,*path),TmpArray);*path=NewPath;}//ifreturn OK;}//IsCorrect

 

这样就可以复制所有类型的文件了。

其实该程序已经写了很久了，一直没有时间贴上来……所有风格不太好，呵呵。

 

当我想乘胜追击，写个文件切割器的时候，失败了。以后有时间的时候再研究吧。
