printf("\nThe given expression is wrong");
printf("\nassignment is not possible");
getch();
exit(0);
}
printf("\nSYMBOL TABLE");
printf("\nSYMBOL\tADDRESS\tTYPE");
for(i=0;i
{
if(isdigit(e[i]))
printf("\n%c\t%u\tCONSTANT",e[i],e[i]);
if(isalpha(e[i]))
{
printf("\n%c\t%u\tIDENTIFIER",e[i],e[i]);
}
}
getch();
}
