Answer:

#include <stack>

#include<iostream>

#include<fstream> // to read imformation from files

#include<string>

using namespace std;

int main() {

   stack<string> data;

   ifstream inFile("postfix.txt");

   string content;

   if (!inFile) {

       cout << "Unable to open file" << endl;

       exit(1); // terminate with error

   }

   while (getline(inFile, content)) {

       data.push(content);

   }

   inFile.close();

   return 0;

}

Explanation:

You were very close. Use the standard <stack> STL library, and make sure the stack elements are of the same type as what you're trying to add, i.e., std::string.

Given the value x=false ,y=5 and z=1 what will be the value of F=(4%2)+2*Y +6/2 +(z&amp;&amp;x)?
Bezzdna [24]
<h2>Answer:</h2>

F = 13

<h2>Explanation:</h2>

Given:

x = false

y = 5

z = 1

F = (4%2)+2*Y +6/2 +(z&&x)

We solve this arithmetic using the order of precedence:

<em>i. Solve the brackets first</em>

=> (4 % 2)

This means 4 modulus 2. This is the result of the remainder when 4 is divided by 2. Since there is no remainder when 4 is divided by 2, then

4 % 2 = 0

=> (z && x)

This means (1 && false). This is the result of using the AND operator. Remember that && means AND operator. This will return false (or 0) if one or both operands are false. It will return true (or 1) if both operands are true.

In this case since the right operand is a false, the result will be 0. i.e

(z && x) = (1 && false) = 0

<em>ii. Solve either the multiplication or division next whichever one comes first.</em>

=> 2 * y

This means the product of 2 and y ( = 5). This will give;

2 * y = 2 * 5 = 10

=> 6 / 2

This means the quotient of 6 and 2. This will give;

6 / 2 = 3

<em>iii. Now solve the addition by first substituting the values calculated earlier back into F.</em>

F = (4%2)+2*Y +6/2 +(z&&x)

F = 0 + 10 + 3 + 0

F = 13

Therefore, the value of F is 13

Write a function called getChar that has no function inputs, but takes in two character inputs from the user (in1 and in2) and o
bearhunter [10]

Answer:

def getChar():

   while True:

       in1 = input('Enter first char: ')

       try:

           if len(in1) != 1:

               raise

           else:

               in2 = input('Enter second char: ')

               if len(in2) != 1:

                   raise

               else:

                   break

       except:

           print('Enter just one character')

   return in1, in2

def chars2string(in1,in2):

   print(in1*5 + in2*5)

def main():

   ls = getChar()

   in1 = ls[0]

   in2 = ls[1]

   chars2string(in1, in2)

if __name__ == '__main__':

   main()

Explanation:

The programming language used is python 3.

The script first defines a function getChar and makes use of a while loop in combination with try and except blocks and IF statements, the code ensures that both inputs that are entered by the user after the prompt are 1 in length. i.e. Just one character. This function returns the two characters that were entered.

The second function that is defined is chars2string this function takes two arguments, It repeats each argument five times and returns a joined string.

Finally, the main function is defined and it calls the getChar function  first, the values that are returned by this function is assigned to two variables, that is then passed on to the chars2string function. The main function is called and the Joined string is printed to the screen.

Label the strength of a beer based on its ABV. For each beer display the beer's name, ABV, and a textual label describing the st
belka [17]

Answer:

By presuming the question expect us to write a program to address the problem and the solution code written in Python is as follow:

  1. beer_name = input("Enter beer name: ")
  2. abv = int(input("Enter ABV value: "))
  3. if(abv > 10):
  4.    label = "Very High"
  5. elif(abv >=6):
  6.    label = "High"
  7. elif(abv >=3):
  8.    label = "Average"
  9. else:
  10.    label = "Low"
  11. print("Beer Name: " + beer_name)
  12. print("ABV value: " + str(abv))
  13. print(label)

Explanation:

Firstly, we can use input function to prompt user to input beer name and ABV value (Line 1 - 2).

Next, create if else if statements to check abv fallen into which range of value and then set a label accordingly (Line 4 -11). For example if abv is 4, the label will be set to "Average".

At last, print the information of beer that includes beer name, abv value and label (Line 13 - 15).
