What is programming language?Programming language is defined as a computer language used to converse with computers by programmers (developers). Orthogonality or simplicity, available control structures, data types, and data structures, syntactic design, support for abstraction, expressiveness, type equivalence, strong versus weak type checking, exception handling, and limited aliasing are among the characteristics of a programming language.
Clarity, simplicity, and unity offer a way to express algorithms as well as a framework for thinking about them. Every possible feature combination has value thanks to orthogonality. Surprisingly, it may frequently be reduced to three basic programming constructs known as loops, selects, and sequences.

Write a MATLAB function named average_of_scores_with_drops The function will have two inputs and two return values. The first input will be a list of scores. The second input will be a postive integer representing the number of scores to drop. It will not be larger than the length of the list. Your function should determine the average of the scores after dropping the specified number of lowest scores. The first return value must be a real number equal to the average score. The second return value must be the number of items that were averaged. Notes: Example Test Case: SCORES
Answer:
-%Define the function.
function [avg, ele_left] = average_of_scores_with_drops(input_list, drop_element)
%Sort the list.
input_list = sort(input_list);
%Compute the length of the list.

Write code that determines the number of full days represented by the number of hours stored in the variable hours and stores that value in the variable full_days. For example, the number of full days in 50 hours is 2. Ignore any leftover hours that don't contribute to a full day. Assume the value of hours has already been initialized. Solve It!
Answer:
hours = 50
full_days = int(hours / 24)
print("The number of full days in " + str(hours) + " hours is " + str(full_days))
Explanation:
Initialize the hours
Since there are 24 hours in a full day, divide the hours by 24. Note that you need to typecast it to the int, because the result is a decimal value by default

print() essentially just calls up the native print dialog for a given window.
But as you're are thinking, it will work on any window or (i)frame.
thus if you write content to a frame, you can then call this to print it.
window.frameName.print();
note the only drawback (and its a big one), is that this calls up the print dialog... not the print preview window... thus the user doesn't really get a chance to see what they are printing and/or scale it to fit their printer/paper.
I personally wish that all browsers would implement the following to handle the above issue.

Explanation:
The web is a vast and endless database of information and has become an invaluable resource for research. That being said it can also bring with it many problems, the main one being unreliable content due to undocumented sources, false testimonies, information with no evidence, etc. The amount of false information on the internet can sometimes make it very time consuming since you have to take the extra step of verifying the information you come across. Despite this, the WEB has information on every topic including current news, and with the wide array of search tools available it is very easy to find what you are looking for.

Fix the error so that the code works correctly
input (“Enter a number: “)
print (num * 8)
How do I fix the error?
Answer:
num = int(input("Enter a number: "))
print(num * 8)
Explanation:
I highlighted the parts that are added
Since you are getting an input from the user, you need to set the result to a variable. In this case, it is num.
Since it is a number, you need to specify the its type. In this case, it may be int.
Also, the quotation marks must be written as seen.
The corrected program which ensures that the program runs correctly is written thus :
num = int(input("Enter a number: ")
#user supplied input should be assigned to the varibale num
print(num * 8)
#multiplies num by 8 and displays the output.
The num variable in the second line isn't attached to any value, therefore, it will throw an error. The user input value should be attached to the variable, 'num' The second line of code multiplies num by 8 and displays the product.Therefore, if the the user input is 3 ; the final result displayed will be : (3 × 8) = 24.

In this question, you should assume that all languages are sets of binary strings interpreted as base-2 integers. The exception is the problem of finding palindromes, which are strings that are identical when reversed, like 00100100, regardless of their numerical value.
This question is incomplete, the complete question is;
The binary string 00100100 is a member of which of the following problems? Remember, a "problem" is a language whose strings represent the cases of a problem that have the answer "yes." In this question, you should assume that all languages are sets of binary strings interpreted as base-2 integers. The exception is the problem of finding palindromes, which are strings that are identical when reversed, like 00100100, regardless of their numerical value.
a) Is the given string a palindromes ?
b) Is the given string a perfect cube?
c) Is the given string greater than 50?
d) Is the given string even?
e) is the given string a perfect square?
Answer:
a) the given binary string is a palindromes
b) the given string is NOT a perfect cube
c) the given string is NOT greater than 50?
d) the given string is an even
e) the given string a perfect square
Explanation:
Given that;
binary string : 00100100
a)
Is the given string a palindromes ?
the given binary string = 00100100
now when you reverse the string, its still going to be : 00100100
so the given binary string is a palindromes
b)
Is the given string a perfect cube
the given string : 00100100 = 36
now 2^3 = 8,
3^3 = 27,
4^3 = 64
so 36 is not a perfect cubic
hence the given string is NOT a perfect cube
c)
Is the given string greater than 50?
the given string : 00100100 = 36
and 36 < 50
so the given string is NOT greater than 50?
d)
Is the given string even?
the given string : 00100100 = 36
and 36 can be divided exactly by 2
so the given string is an even
e)
is the given string a perfect square?
the given string : 00100100 = 36
now 6^2 = 36 i.e 6 multiply by 6 = 36
therefore the given string a perfect square
