1. Assume you are given a boolean variable named is Square and a 2-dimensional array that has has been created and assigned to a2d. Write some statements that assign true to is Square if the entire 2-dimensional array is square meaning every row and column has the same number of elements as every other row and column.2. Assume you are given an int variable named n Positive and a 2-dimensional array of ints that has been created and assigned to a 2d. Write some statements that compute the number of all the elements in the entire 2-dimensional array that are greater than zero and assign the value to n Positive.
3. Declare a multi-dimensional array of ints , westbound Holland Tunnel Traffic that can store the number of vehicles going westbound through the Holland Tunnel on a particular hour on a particular day on a particular week on a particular year. The innermost dimension should be years, with the next being weeks, and so on.

Create a cell reference in a formula by typing in the cell name or         a. right-clicking the cell. b. clicking the cell. c. clicking the column where the cell is located. d. clicking the row where the cell is located.

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';

The most accurate readings that you can take on an analog vom are when the meter's pointer is at the a. center scale. b. extreme right. c. near right. d. extreme left.
