following is the infix expression - A-(B/C+(D%E*F)/G)*H
Can you please tell me what will be it's postfix expression
1.ABC/D%EF*G/+H*-
or
2.ABC/DE%F*G/+H*- .
I am just not able to decide whether it will be D%E or DE% I think that after scanning D, "%" will be moved to stack & then E will be written & then by comparing * & %, % will take place, but on internet it is showing that DE% is right. Right answer with explanation will be appreciated.
Your second option is right.
Operators are not pushed to the stack; they pop two values from the stack, apply the operation, and push the result to the stack. Therefore, since
%
and*
share the same precedence, they are applied left to right:
