Question

Use only if else nested if else only otherwise your answer won't be entertained.

Problem 1(b): Write a program that gives remainder without using modulus operator and loops. The first number entered will be dividend and second number entered will be divisor.

Sample input: 15 6

Sample output: Remainder is 3

In a right triangle, the square of the length of one side is equal to the sum of the squares of the length of the other two sides. Write a C++ program that takes in lengths of the three sides of a triangle, and then outputs whether the triangle is right or not.

 

Write a C++ program that asks a user to enter 2 numbers. Assign the numbers to integers ‘bigNumber’ and ‘littleNumber’. Check if bigNumber is not bigger than littleNumber. If yes, display “The littleNumber is bigger.” Else display “The bigNumber is bigger.”. Now check if they are evenly divisible.

If they are evenly divisible, display “They are evenly divisible” else display,” They are not evenly divisible”. If they are evenly divisible, check if they are the same number. If they are same, display “They are same” else, display “Not same”. 

The B's(AF) department of Must needs your help to assign Letter grades to newly admitted students. Write a C++ program that takes the marks of the student and display a letter grade according to the following rules. If a student takes marks greater than 85 out of 100 then he/she must be awarded A grade letter, if marks are between 75 and 85 out of 100 then you may assign the student grade B, for the range 65 to 75, C is given and for range 50 to 65 grade D will be awarded. For all marks obtained below 50 must be categorized as F grade. 

 

Write a C++ program that plays the game of “Rock, paper, scissors.” In this game, two players simultaneously say (or display a hand symbol representing) either “rock,” “paper,” or “scissors.” The winner is the one whose choice dominates the other. The rules are: paper dominates (wraps) rock, rock dominates (breaks) scissors, and scissors dominate (cut) paper. Declares and initializes First player and second player variables at the start).

You can use ‘r’=rock, ‘p’=paper, ’s’=scissors

Examples:

First player = r

Second player = r

Output: Draw

First player = r

Second player = p

Output: 2nd player wins

Write a C++ program of a Body Mass Index (BMI) calculator application that reads the user’s weight and height and then calculates and displays the user’s body mass index. The formula for calculating BMI is:

English BMI Formula

BMI = ( Weight in Pounds / ( Height in inches x Height in inches ) ) x 703

Metric BMI Formula

BMI = ( Weight in Kilograms / ( Height in Meters x Height in Meters ) )

Also, the application should display the following information from the scale provided below.

BMI VALUES    Underweight: less than 18.5; Normal: between 18.5 and 24.9; Overweight: between 25 and 29.9; Obese: 30 or greater

Note: Your program should check that the height and weight entered are not negative. If the entered data is incorrect display a message accordingly.

People who deal with historical dates use a number called the Julian day to calculate the number of days between two events. The Julian day is the number of days that have elapsed since January 1, 4713 B.C. For example, the Julian day for October 16, 1956, is 2435763.

There are formulas for computing the Julian day from a given date, and vice versa. One very simple formula computes the day of the week from a given Julian day:

Day of the week = (Julian day + 1) % 7 where % is the modulus operator. This formula gives a result of 0 for Sunday, 1 for Monday, and so on, up to 6 for Saturday. For Julian day 2435763, the result is 2 (Tuesday). Your job is to write a C++ program that requests and inputs a Julian day, computes the day of the week using the formula, and then displays the name of the day that corresponds to that number.

Your output might look like this:

Enter a Julian day number and press Enter.

2451545

Julian day number 2451545 is a Saturday.

Enter a Julian day number and press Enter.

2451547

Julian day number 2451547 is a Monday.

 
Write a C++ program that takes an integer variable as input from user and checks whether the input is an even number and print the desired message
