Addition of Two Numbers
Adding two numbers in programming is essentially the same as adding two numbers in general arithmetic. A significant difference is that in programming, you need to pay attention to the data type of the variable that will hold the sum of two numbers.
C++
C++ is a general-purpose hybrid language, which supports both OOPs and procedural language designed and developed by Bjarne Stroustrup. It began in 1979 as “C with Classes” at Bell Labs and first appeared in the year 1985 as C++. It is the superset of C programming language, because it uses most of the C code syntax. Due to its hybrid functionality, it used to develop embedded systems, operating systems, web browser, GUI and video games.

- C++ code 1 year = 15 months 1 month = 30 days write a function that takes an int parameter that represents the number of days, and converts the number of days to years, months, and days and returns this information in a struct So for example, it will convert 800 days into a struct that represents one year, 11 months, and 20 daysstruct date{ int day; int month; int year; }; Write a function named void increaseDay(struct date *d) that increases the value of a variable of struct date type with integer year, month, and day members by one day. Write a function named void decreaseDay(struct date *d) that decreases the value of a variable of struct date type with integer year, month, and day members by one day. Write a C program that reads from the user a date in d/m/y format and the amount of increase or decrease as an integer. Display the new date in d/m/y format. You may call related functions as many as given increase or decrease value. Note 1: You do not need to consider leap years. Use always 28 days for month February. Note 2: Do not modify the function prototypes. Sample Input1: Sample Output1: 12/8/1990 -5 7/8/1990 Sample Input2: Sample Output2: 26/2/2005 5 3/3/2005 Sample Input3: Sample Output3: 29/12/1998 7 5/1/1999…Lowest Score Drop Write a program that calculates the average of a group of test scores, where the lowest score in the group is dropped. It should use the following functions: void getScore() should ask the user for a test score, store it in a reference parameter variable, and validate it. This function should be called by main once for each of the five scores to be entered. void calcAverage() should calculate and display the average of the four highest scores. This function should be called just once by main and should be passed the five scores. int findLowest() should find and return the lowest of the five scores passed to it. It should be called by calcAverage, which uses the function to determine which of the five scores to drop. Input Validation: Do not accept test scores lower than 0 or higher than 100.
- C++ Please! Also please don't use functions, arrays, or classes. Just basic c++ please. Password Verifier Write a C++ program to verify that a user’s password meets the following criteria: 1. The password should be at least 6 characters long. 2. The password should contain at least one uppercase and one lowercase letter. 3. The password should have at least one digit. Your program should ask the user for a password and verify that it meets the following criteria. If it doesn’t a message should be displayed telling the user why.Computer Fundamentals and Programming 2 Write a program that determines a student’s grade. The program will accept 3 scores and computes the average score. Determine the grade based on the following rules: - If the average score is equal or greater than 90, the grade is A. - If the average score is greater than or equal to 70 and less than 90, the grade is B. - If the average score is greater than or equal to 50 and less than 70, the grade is C. - If the average score is less than 50, the grade is F.

- A postfix expression is an expression in which each operator follows its operands. Figureabove shows an examples of postfix expressions.The advantage of postfix form is that there is no need to group subexpressions in parentheses or to consider operator precedence. One may have used pocket calculators that require entry of expressions in postfix form.Write a program that simulates the operation of a calculator by scanning an integer expression in postfix form and displaying its result. The program should push eachinteger operand onto the stack. When an operator is encountered, the top two operands are popped, the operation is performed on its operands, and the result is pushed back onto the stack. The final result should be the only value remaining on the stack when the end of the expression is reached. This program scans a postfix expression and evaluates it. The Postfix expression must be followed by a space and a '?' to mark the end of the expression. One must use stack and the…Language: Python 3 A particular talent competition has 5 judges, each of whom awards as score between 0 and 10 to each performer. Fractional scores, such as 8.3, are allowed. A performer's final score is determined by dropping the highest and lowest score received, then averaging the 3 remaining scores. Write a program that uses these rules to calculate and display a contestant's score. It should include the following functions: -getJudgeData() should ask the use for a judge's score, store in a parameter variable, and validate it. This function should be called by main program once for each of the 5 judges. -calcScore(score1, score2, score3, score4, score5) should calculate and return the average of the 3 scores that remain after dropping the highest and lowest scores the performer received. This function should be called just once by main and should be passed the 5 scores. Two additional functions, described below, should be called by calcScore, which uses the returned information to…write a C++ program. Write a program that calculates and displays the average of a group of test scores, all integers, after the lowest score in the group has been dropped. There are six test scores in the group. The program must contain only the following functions in additionto the main:• void getScore should ask the user for a test score, store it in a referenceparameter variable, and validate it. This function should be called by the mainfunction once for of the six scores to be entered by the user.• double calcAverage should calculate and return the average of the five highest scores. This function should be called just once by the main function, and should be passed the six scores. Use pass by reference to receive the lowest test score.• int findLowest should find and return the lowest of the six scores passed to it. It must be called by the calcAverage function, which uses it to determine which of the six scores to drop.• void displayResults should be called by the main function…
