Suppose you work for a technology company and you are taking a business trip to Japan to purchase some parts. The Japanese use yen for their currency. When you arrive in Japan, the
manufacturers have listed the prices in yen. To figure out how much you are spending, you will
need to convert the prices in yen to U. S. dollars. You know that one U. S. dollar equals 105.06 yen
at the time of your trip, so you use your spreadsheet to make this conversion. You enter a price
in one cell and in another cell, you enter a formula that multiplies the price by 105.06. In this
way, you can quickly see how much an item costs in U. S. dollars.
Objectives
Create a spreadsheet to convert foreign currency to U. S. dollars.
Directions
Part 1: Select ten foreign currencies and find the current exchange rate. Since currency
exchange rates change often, you will need to look up the exchange rates. You can call a bank or
look for foreign currency exchange rates on the Internet or in a newspaper.
Part 2: Create a spreadsheet that lists the ten currencies you chose. For each currency, enter an
amount and create a formula to convert it to U. S. dollars. Make sure to include dollar signs in
the appropriate cells

We as humans write math expression in infix notation, e.g. 5 + 2 (the operators are written in-between the operands). in a computer’s language, however, it is preferred to have the operators on the right side of the operands, i.e. 5 2 +. for more complex expressions that include parenthesis and multiple operators, a compiler has to convert the expression into postfix first and then evaluate the resulting postfix.write a program that takes an “infix” expression as input, uses stacks to convert it into postfix expression, and finally evaluates it. it must support the following operations: + - / * ^ % (example infix expression: (7 - 3) / (2 + 2)postfix expression: 7 3 - 2 2 + /result: 1guidelines: 1. you will need to use stacks in three placesa. one for the parenthesis check [char stack]b. one during infix to postfix [char stack]c. one during evaluation [int stack]for a and b above, you can use same array and same push, pop method as both ofthem are char. but for evaluation you have int stack and you might consider to createanother push pop method to handle it. maybe push_int, pop_int, etc. or find otherstrategy to utilize existing push pop method2. you can create a function for obtaining operator priority. that function should take anoperator as input and return its priority as an integer. this function will you a lot andreduce repeated code3. during evaluation you will need to convert char into integer. example for single digit: char c = '5'; int x = c - '0';
