SUMMARY

The correct postfix expression for the infix notation "a*b/c+d/e/f" is "ab*c/de/f/+". This conclusion is based on the evaluation of operators with the same priority, specifically multiplication (*) and division (/), which are processed from left to right. The expression is structured as ((a*b)/c)+((d/e)/f), ensuring accurate conversion to postfix notation.

PREREQUISITES
  • Understanding of infix and postfix notation
  • Knowledge of operator precedence and associativity
  • Familiarity with mathematical expressions and their evaluation
  • Basic skills in algorithm design for expression conversion
NEXT STEPS
  • Study the Shunting Yard algorithm for converting infix to postfix notation
  • Learn about operator precedence rules in programming languages
  • Explore stack data structures for managing operator evaluation
  • Practice converting various infix expressions to postfix format
USEFUL FOR

Students learning about data structures, computer science enthusiasts, and anyone interested in understanding expression evaluation and conversion techniques.

Code: 
Here is my problem a*b/c+d/e/f:
*there is no code because professor ask me do hand write it out*

My answer: abc*/def//+is this correct?

Hi needOfHelpCMath! (Smile)

It should be: [M]ab*c/de/f/+[/M]

That's because * and / have the same priority and are evaluated left to right.
So the expression is evaluated as [M]((a*b)/c)+((d/e)/f)[/M].
The postfix expression reflects that.

thank you very much clarifies my mistakes!
