A student creates a Raptor program that allows the user to input a list of first names into one array and last names into a parallel array. Student’s program allows the input to be terminated when the user enters a sentinel character. Student’s program produces a list of email addresses where the address is of the following form:__deleted3ca2a6f87c5294b52729d d96452132238ff30a93885ec2a6df5de376 de0437acdeleted__. What did the student do?a) Student declares and uses valid variables and arrays with the appropriate data types. b) Student evaluates the input, processes the data and determines the appropriate solution. c) Student creates formulas that can produce correct results. d) Student incorporates logical conditions that covers all boundaries specified by the problem. e) Student uses defensive programming techniques. f) Student shows strong evidence of applying program development strategies as discussed in the reading. g) Student enters in the appropriate documentation. h) Student shows mastery of algorithm design.

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';

Hyperactive media sales has 10 windows 7 laptop computers used by sales-people in the organization. each laptop computer has several customized applications that are used during the sales process as well as customer relationship management software. all of the applications on the laptops are difficult to configure and have large data files. if all of the laptops have current hardware, what is the easiest way to install windows 10 on them?
