C语言文件应用,请高手指教!
#include<stdio.h>#include<stdlib.h>#include<conio.h>#include<string.h>int main(){FILE *fptr1,*fptr2,*fptr3;char temp[15],temp1[15],temp2[15];if((fptr1=fopen("a.txt","r"))==null){printf("can not open file");exit(0);}if((fptr2=fopen("b.txt","r"))==null){printf("can not open file");exit(0);}if((fptr3=fopen("ab.txt","w"))==null){printf("can not open file");exit(0);}clrscr();while(strlen(fgets(temp1,15,fptr1))>1){fgets(temp2,15,fptr1);fputs(temp1,fptr3);fputs(temp2,fptr3);strcpy(temp,temp1);do{fgets(temp1,15,fptr2);fgets(temp2,15,fptr2);}while(strcmp(temp,temp1)!=0);rewind(fptr2);fputs(temp2,fptr3);}fclose(fptr1);fclose(fptr2);fclose(fptr3);}其中，a.txt中的数据是这样的：hejie tianjingliying shanghailiming chengduwangpin chongqingb.txt中的程序是这样的：liying 12345hejie 8764wangpin 87643liming 7654322想通过此程序，将ab.txt变为：hejie tianjing8764liying shanghai12345liming chengdu7654322wangpin chongqing87643或者：hejie tianjing 8764liying shanghai 12345liming chengdu 7654322wangpin chongqing 87643试问：程序错在什么地方。感激。另外在linux下运行是无法识别#include<conio.h>这个函数，该怎样处理。提问者：dazui33

你的程序思路在内层循环哪儿有些混乱，实现不了你所要求的功能，按照以下代码改就对了；fgets()函数读取的字符串里含有空格，比如他第一次读取的是"hejie tianjing"，这样就无法进行下面的比较，所以用fscanf(fp,"s",buf)代替。下面是改正后的代码：#include<stdio.h> #include<stdlib.h> #include<conio.h> #include<string.h> #define null NULLint main() { FILE *fptr1,*fptr2,*fptr3; char temp[15],temp1[15],temp2[15]; if((fptr1=fopen("a.txt","r"))==null) { printf("can not open file"); exit(0); } if((fptr2=fopen("b.txt","r"))==null) { printf("can not open file"); exit(0); } if((fptr3=fopen("ab.txt","w"))==null) { printf("can not open file"); exit(0); } //clrscr(); //while(strlen(fgets(temp1,15,fptr1))>1) while(fscanf(fptr1,"%s",temp1)!=EOF) { fgets(temp2,15,fptr1); fputs(temp1,fptr3); fputs(temp2,fptr3); strcpy(temp,temp1); do { if(fscanf(fptr2,"%s",temp2)==EOF) { printf("Something Error!\n"); exit(1); } }while(strcmp(temp,temp2)!=0); fgets(temp2,15,fptr2); fputs(temp2,fptr3); rewind(fptr2); } fclose(fptr1); fclose(fptr2); fclose(fptr3); } ab.txt内容：hejie tianjing 8764 liying shanghai 12345 liming chengdu 7654322 wangpin chongqing 87643 linux里conio.h在那里不知道还有，clrscr()函数值在TC里有吧？我用的是VC,所以找不见那个函数，将它注释掉了。你的新要求的参考答案：#include<stdio.h> #include<stdlib.h> #include<conio.h> #include<string.h> #define null NULLint main() { FILE *fptr1,*fptr2,*fptr3; int lock=0; char temp[15],temp1[15],temp2[15],temp3[15]; if((fptr1=fopen("a.txt","r"))==null) { printf("can not open file"); exit(0); } if((fptr2=fopen("b.txt","r"))==null) { printf("can not open file"); exit(0); } if((fptr3=fopen("ab.txt","w"))==null) { printf("can not open file"); exit(0); } //clrscr(); //while(strlen(fgets(temp1,15,fptr1))>1) while(fscanf(fptr1,"%s",temp1)!=EOF) { fgets(temp2,15,fptr1); strcpy(temp3,temp2); //fputs(temp1,fptr3); //fputs(temp2,fptr3); strcpy(temp,temp1); do { if(fscanf(fptr2,"%s",temp2)==EOF) {// printf("Something Error!\n"); lock=1; break;// exit(1); } }while(strcmp(temp,temp2)!=0); if(lock==1) { lock=0; rewind(fptr2); continue; } lock=0; fputs(temp1,fptr3); fputs(temp3,fptr3); fgets(temp2,15,fptr2); fputs(temp2,fptr3); rewind(fptr2); } fclose(fptr1); fclose(fptr2); fclose(fptr3);} /*a.txt:hejie 23 hunan 45 shanghai 12 b.txt:hejie K hubei H shanghai G ab.txt:hejie 23 K shanghai 12 G *//*********************小恩 制作********************/ -
