Make a Scanner that will read a file whose data represents how many coins you have and write to another file how much money you have. The file will have a number followed by the type of coin. For example, if the file was: 3 pennies 2 quarters 8 pennies 3 nickels 4 dimes your output should be $1.16. The same type of coin can be repeated multiple times! Test your code by making files with the following text: 3 pennies 3 pennies 8 pennies (output should be $0.14) 0 pennies 2 nickels 3 dimes 3 quarters (output should be $1.15) 4 dimes 2 quarters 9 nickels 4 dimes (output should be $1.75)

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';
