有几个地方的fpa,fpb 搞混了，putchar(fgetc(fb))你还有个括号没括！程序如： #include "stdio.h" main() { FILE *fpa,*fpb; if((fpa=fopen("a.txt","r"))==NULL) {printf("error1a");exit(0);} if((fpb=fopen("b.txt","w"))==NULL) {printf("error1b");exit(0);}

while(!feof(fpa)) fputc(fgetc(fpa),fpb);

if(fclose(fpa)||fclose(fpb)){printf("error2a'or'b");exit(0);}

if((fpb=fopen("b.txt","r"))==NULL) {printf("error1b");exit(0);}

while(!feof(fpb)) putchar(fgetc(fpb)); if(fclose(fpa)){printf("error2b");exit(0);}

}
