May 29, 2022 · To convert a** postfix expression** into a** prefix,** you first need to determine the letters that make up the** expression.** This is done by subtracting the letters A from the letters C. For example, the** expression** “my email address is peter” would be converted to “ [email protected] ”.. If they are written before the operand, then they are termed as **prefix** operators. However, if they are written after the operand, then they are termed as **postfix** operators. The main difference between the two is the placement: either before or after the operand. Furthermore, their placement also has an impact on the values of the operant. For example, The above expression can be written in the **prefix** form as / * A + B **C** D. This type of expression cannot be simply decoded as infix expressions. **Postfix**: **In** **postfix** expression, an operator is written after its operands. This notation is also known as "Reverse Polish notation". A short open-source program that detects whether an equation is in infix, **postfix** or **prefix** notation and then calculates the answer of the equation and prints it for the user. The program works by checking the format of the equation and using the penultimate and final index of the equation to determine its notation. Solution: Step 1: Evaluate a++. Since ++ is **postfix**, the current value of a will be used in the expression then it will be incremented. The expression now becomes: **c** += 10 * 5 - --b; Step 2: Evaluate --b. Since -- is **prefix**, the value of b will be decremented immediately. The expression now becomes: **c** += 10 * 5 - 19;. Example: To convert "(A + B) * **C** " to **prefix** : Reverse the infix expression (A+B)***C** becomes **C***(B+A). . Nov 21, 2013 · A **postfix** expression (also called Reverse Polish Notation) is a single letter or Every **postfix** string longer than a single variable contains first and second operands followed by an operator. **In** C/C++, precedence of **Prefix** ++ (or **Prefix** -) has higher priority than dereference (*) operator, and precedence of **Postfix** ++ (or **Postfix** -) is higher than both **Prefix** ++ and *. If p is a pointer then *p++ is equivalent to *(p++) and ++*p is equivalent to ++(*p) (both **Prefix** ++ and * are right associative).
