使用本程序时，请先编译程序ldw并运行然后编译dong并运行 即可观察效果欢迎下载运行并提出改进意见，共同进步建议VC+6.0打开Ldw：#include#include#includechar a=ldw;char b=dong;char bufa256;char bufb256;char buftemp256;int len=0;FILE *fp,*fq;extern flag;void listen()fq=fopen(c:chat2.txt,r);fscanf(fq,%s,bufb);/fq-bufblen=strlen(bufb);/printf(bufb len =%dn,len);/if(len0)bufblen=0;printf(dong:%sn,bufb);fclose(fq);void speak()printf(ldw: );fgets(bufa,256,stdin);bufastrlen(bufa)-1=0;fp=fopen(c:chat1.txt,w);fprintf(fp,%sn,bufa);/bufa-fpif(strncmp(bufa,!,3)=0)printf(对方已下线！n);fclose(fp);unlink(c:chat1.txt); exit(0);fclose(fp);int main()memset(bufa,0,sizeof(bufa);memset(bufb,0,sizeof(bufb);memset(buftemp,0,sizeof(buftemp);printf(flag =%dn,flag);/printf(这是ldw的终端！n);/while(1)while(1)if(fp=fopen(c:chat1.txt,w)=NULL)printf(系统错误！程序异常退出.);exit(1);if(fq=fopen(c:chat2.txt,r)=NULL)printf(系统错误！程序异常退出.);exit(1);listen();speak();return 0;/*printf(ldw:);fp=fopen(c:chat1.txt,w);fgets(bufa,256,stdin);bufastrlen(bufa)-1=0;fprintf(fp,%sn,bufa);if(strncmp(bufa,!,3)=0)fclose(fp);exit(-1);fclose(fp);*/*printf(.);fq=fopen(c:chat1.txt,r);fscanf(fq,%s,bufb);len=strlen(bufb);if(len0)bufblen=0;printf(ldw:%sn,bufb);fclose(fq);*/Dong：#include#include#includeint flag=988;int mggain()char a=ldw;char b=dong;char bufa256;char bufb256;char buftemp256;int len=0;FILE *fp,*fq;memset(bufa,0,sizeof(bufa);memset(bufb,0,sizeof(bufb);memset(buftemp,0,sizeof(buftemp);printf(这是dong的终端！n);if(fp=fopen(c:chat2.txt,w)=NULL)printf(系统错误！程序异常退出.);exit(1);while(1)if(fq=fopen(c:chat1.txt,r)=NULL)printf(系统错误！程序异常退出.);exit(1);fq=fopen(c:chat1.txt,r);fscanf(fq,%s,bufb);len=strlen(bufb);printf(bufb len =%dn,len);/if(len0)bufblen=0;printf(ldw: %sn,bufb);fclose(fq);printf(dong:);fgets(bufa,256,stdin);bufastrlen(bufa)-1=0;fp=fopen(c:chat2.txt,w);fprintf(fp,%sn,bufa);if(str
