Considering the schema above,
Which of the following finds the first name and last name10+ of all employees who are professors with the title as 'assistant professor' and first names starting with the letter W.
A. SELECT fname, lname FROM employee WHERE fname LIKE 'W%' AND ssn IN ( SELECT ssn FROM professor WHERE title = 'assistant professor' );
B. SELECT fname, lname FROM employee WHERE fname LIKE 'W%' AND ssn = (SELECT ssn FROM professor WHERE title = 'assistant professor');
C. SELECT fname, lname FROM employee INNER JOIN professor ON employee. ssn = professor. ssn WHERE fname LIKE "W%" AND title = 'assistant professor';
D. SELECT fname, lname FROM employee WHERE fname LIKE 'W%' AND ssn = (SELECT ssn FROM employee WHERE title = 'assistant professor');
E. All of these
F. None of these

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';
