Explain the distinction between typed variables that are explicitly declared and typed variables that are implicitly declared.

In programming a good identifier is self-descriptive and mnemonic ("assisting memory" / "assists in remembering something"). Which variable name below satisfies this approach best? a) energyInCalories. b) E c) nrg d) x

What is the difference between a parameter variable and an argument variable in computer programming?

C++ Help me fix my code please! I'm missing something and can't figure it out. Code and error picture are below. #include <iostream> using namespace std; class Employee{ public: string first_name; string last_name; int monthly_sal; int increment; Employee() { first_name=""; last_name=""; monthly_sal=0; increment=0; } void setFirst_Name(string first_name) { this->first_name=first_name; } void setLast_Name(string last_name) { this->last_name=last_name; } void setSal(int monthly_sal) { if(monthly_sal<0) this->monthly_sal=0; this->monthly_sal=monthly_sal; } void setInc(int increment) { monthly_sal += increment; } string getFirst_Name() { return first_name; } string getLast_Name() { return last_name; } int get_salary() { return monthly_sal; } int get_increment() { return increment;...

Design a circuit that multiply two 2 bit numbers ( A1A0 , B1B0) by using 4-to-16 Decoder.

Write program in C++ Language The other solutions on chegg were incorrect! Please read carefully! Write a program that defines and tests a class called COP3014. The class resembles aclassroom. It has the following grading scheme:3 quizzes 20 points each 20%Mid term 100 points 30%Final 100 points 50%Based on the total grade of any student for the course, the letter grade of each student can becomputed as follows:Any grade of 90 or more is an A, any grade of 80 or more (but less than 90) is a B, any grade of70 or more (but less than 80) is a C, any grade of 60 or more (but less than 70) is a D, and anygrade below 60 is an F.This class needs to have some member variables. The first name, last name, the Z-number, thegrades, the total grade and final letter grade are all considered to be private member variablesof this class.The class should also have the following public member functions/procedural attributes that canbring the objects (students of the class) to life and give them some...

Destructor, copy constructor and operator= are special functions provided by C++. Group of answer choices True False

Problem Statement: A painting company has determined that for every 115 square feet of wall space, one gallon of paint and eight hours of labor will be required. The company charges 20ドル.00 per hour for labor. Develop a Java program that performs the following: Input Requirements: Set up the data for the following as named constants for one gallon of paint: 115 square feet of wall space eight hours of labor Also, set up a named constant for the following: 20ドル.00 per hour for labor Enter the following input data at the keyboard: The square feet of wall space to be painted The price of the paint per gallon Processing: Your program is to perform the following calculations: The number of gallons of paint required The hours of labor required The cost of the paint The labor charges The total cost of the paint job Output Requirements: The square feet of wall space to be painted The price of the paint per gallon The number of gallons of paint required The hours of labor...

Please answer in C++ / Text book question / C++ for scientist and Engineers 3rd edition Construct a class named Fractions containing two integer data members named num and denom, used to store the numerator and denominator of a fraction having the form num/denom. Your class should include a default constructor that initializes num and denom to 1 and four operator functions for adding, subtracting, multiplying, and dividing the two fractions, as follows: Addition: a/b + c/d = (a * d + b * c) / (b * d)Subtraction: a/b - c/d = (a * d - b * c) / (b * d)Multiplication: a/b * c/d = (a* c) / (b * d)Division: (a/b) / (c/d) = (a * d) / (b * c) Finally, your class should have a member function that reduces each fraction to its terms (refer to Exercise 15 in Programming Projects for Chapter 6 for how to do this) as well as input and output functions for entering and displaying a fraction. thanks
