compile my code
and test ur prog :)
i think this prob description is not clear

#include <stdio.h>
#include <ctype.h>
FILE *fp,*fx;
int main()
{
long false,com=0,sum=0;
char kao,chr;
fp=stdin; fx=stdout;
// fp=fopen("1027.in","r"); fx=fopen("1027.out","w");
false=0;
kao=0;
while(fscanf(fp,"%c",&chr)!=EOF)
   {
    if(com&&chr==')'&&kao=='*') com=0;
    else if(!com&&chr==')'&&kao=='*'&&!sum) false=1;
    else if(!com&&chr==')'&&kao=='*'&&sum) sum--;
    else if(!com)
      {
     if(chr=='(') sum++;
     else if(chr=='*'&&kao=='(') { sum--; com=1; chr=0; }
     else if(chr==')') sum--;
     else if(sum>0&&!(isdigit(chr)
||chr=='\r'||chr=='\n'||chr=='='||chr=='+'||chr=='-
'||chr=='*'||chr=='/'))
      false=1;
      }
    if(false||sum<0) break;
    kao=chr;
   }
if(false||sum>0||sum<0||com) fprintf(fx,"NO\n");
else fprintf(fx,"YES\n");
// fclose(fp); fclose(fx);
return 0;
}

Thank you anyway.But I didn't know C or C++ Ural_Happy New Year! 24 Apr 2003 12:13

If you can test my cole and find my bugs, thanks a lot.
