怎样用C语言写一个程序 打开记事本 并输入一段文字,写完一份c语言代码后怎么写第二份

#include <stdlib.h>#include <stdio.h>#define Line 1024int main(){ //文件名及文件指针 char infile[]="D:\Wtmp\1.txt"; char outfile[]="D:\Wtmp\2.txt"; FILE *fpi,*fpo; //暂存器 char *outbuf; outbuf = (char *)malloc(Line*sizeof(char))

; if( ( fpi=fopen(infile,"r") ) == NULL ) { printf("文件打开%s失败 ",infile)

; return 3; } if( ( fpo=fopen(outfile,"w") ) == NULL ) { printf("文件打开%s失败 ",outfile)

; return 3; } while(1) { //outbuf要干净 //memset(outbuf,0,Line); outbuf=0; fprintf(fpo,"%s",outbuf)

; if (fgets(outbuf,Line,fpi)==NULL) { break; }//全部行结束退出循环 //DelStr(outbuf,"删除字符串")

; //重载函数DelStr //DelStr(outbuf,"要替换字符串","替换成字符串")

; //重载函数DelStr fprintf(fpo,"%s",outbuf); } //关闭文件 free(outbuf); fclose(fpi); fclose(fpo); return 0;}
