【C语言】没事可以试试这个小程序，使用文件操作，模拟实现一个简单的文件拷贝工具！

#include<stdio.h>#include<stdlib.h>#include<Windows.h>int main(int argc,char* argv[]){FILE* pfRead = NULL;FILE* pfWrite = NULL;int ch = 0;if(argc != 3){perror("参数出错\n");exit(EXIT_FAILURE);}pfRead = fopen(argv[1],"r");if(pfRead == NULL){perror("open file for read\n");exit(EXIT_FAILURE);}pfWrite = fopen(argv[2],"w");if(pfWrite == NULL){fclose(pfRead);perror("open file for write\n");exit(EXIT_FAILURE);}while((ch = fgetc(pfRead)) != EOF){fputc(ch,pfWrite);}fclose(pfRead);fclose(pfWrite);system("pause");return 0;}
