Question

Convert the given infix expression to a postfix expression: a + b * c

Answer #1

:)

Convert the following infix expressions to postfix.
a * b + c – d
a + b / (c + d)

in Java
In this exercise, you'll write a Java version of the
infix-to-postfix conversion algorithm. These same mechanisms can be
used as a part of writing a simple compiler.
Write class InfixToPostfixConverter co convert
an ordinary infix arithmetic expression (assume a valid expression
is entered) with single-digit integers (to make
things easier) such as
(6 + 2) • 5 - 8 / 4
to a postfix expression. The postfix version (no parentheses are
needed) of this infix expression is
6...

Use C++
Your program should expect as input from (possibly re-directed)
stdin a series of space- separated strings. If you read a1 (no
space) this is the name of the variable a1 and not "a" followed by
"1". Similarly, if you read "bb 12", this is a variable "bb"
followed by the number "12" and not "b" ,"b", "12" or "bb", "1"
,"2". Your program should convert all Infix expressions to Postfix
expressions, including expressions that contain variable names. The...

(For Python)
Evaluating Postfix Arithmetic Expressions. In this project you
are to implement a Postfix Expression Evaluator as described in
section 7-3b of the book. The program should ask the user for a
string that contains a Postfix Expression. It should then use the
string's split function to create a list with each token in the
expression stored as items in the list. Now, using either the stack
classes from 7.2 or using the simulated stack functionality
available in a...

Something is either messed up in my operator overload <<,
covertopostfix function, or my main output. Cannot figure it out.
please help. Please comment your changes too.
Program below is supposed to be outputting like this:
InFix is: A+B-C
Post fix is: A B + C -
InFix is: A+C
Post fix is: A C +
InFix is: x*(y+z)-(w+t)
Post fix is: x y z + * w t + -
InFix is: A+B*(C+D)-E/F+G+H
Post fix is: A B C...

Find is the final result of evaluating the following
postfix expression using a stack. Show each push and pop
operation.
85 5 / 4 * 5 6 +
10 5 - * +

For the postfix expressions, 32 5 3 + / 5 *, trace the algorithm
for evaluating postfix expressions by showing the contents of the
stack immediately before each of the tokens marked with a caret is
read. Also, give the value of the postfix expression.

Create a program using Binary Trees in Java to
do the following
1. Verify a given expression is balanced in regards to
parentheses
2. covert an infix expression to a postfix expression
3. Evaluate the expression
Given expressions:
String s[] = {"5 + ) * ( 2",
" 2 + ( - 3 * 5 ) ",
"(( 2 + 3 ) * 5 ) * 8 ",
"5 * 10 + ( 15 - 20 ) ) - 25",...

10) What is the value of this prefix expression when read as an
infix expression? Draw the ordered rooted tree corresponding to the
below arithmetic expressions written in prefix notation.
a) x,/,9,3,+,x,2,4,-,7,6
b) -,x,2,/,8,4,3
c) 5,2,1,-,-,3,1,4,+,+,x
d) 9,3,/,5,+,7,2,-,x

The grammar below generates Boolean expressions in prefix
notation:
B → O B B | not B | id O → and | or
a) Write an attribute grammar to translate Boolean expressions
into fully parenthesized infix form. For example, expression and
and a or b c d turns into the following fully parenthesized
expression ((a and (b or c)) and d).
b) Now write an attribute grammar to translate the Boolean
expressions into parenthesized expressions in infix form without...
