(For thought) Although you have concentrated on operations involving integer and floatingpoint numbers, C++ allows adding and subtracting characters and integers. (These operations are possible with characters because they’re integer data types and are stored by using integer codes.) Therefore, characters and integers can be mixed in arithmetic expressions. For example, if your computer uses the ASCII code, the expression

C# chooses a unifying type for the result you must choose a unifying type for the result you must provide a cast you receive an error messagearrow_forwardLanguage: JAVA Problem 1: Decimal to Binary Conversion Write a program that takes an integer value as an input and converts that value to its binary representation; for instance, if the user inputs 17, then the output will be 10001. Do not forget to check for valid input, which means if the user inputs a type of data other than an integer re-prompt the user to enter a valid value. The output binary number can be a string. Sample input and output: Enter an integer > a You entered an invalid type. Try again. Enter an integer > 17 10001arrow_forward
- 4. Odd-Even-inator by CodeChum Admin My friends are geeking out with this new device I invented. It checks if a number is even or odd! ? Do you want to try it out? Instructions: In the code editor, you are provided with a function that checks whether a number is even or odd. Your task is to ask the user for the number of integer, n, they want to input and then the actual n number values. For each of the number, check whether it is even or odd using the function provided for you. Make sure to print the correct, required message. Input 1. Integer n 2. N integer valuesarrow_forwardTOPICS THAT CAN BE USED: OOP, Pointers and Functions, Arrays and Structs, Repetition Statements, Introduction to C++ PROBLEM: Write a program which accepts a number corresponding to a plane figure: 1. Right Triangle 2. Rectangle 3. Circle The program will then ask for the following: base and height - if the previous input is 1 (right triangle) width and length - if the previous input is 2 (rectangle) radius - if the previous input is 3 (circle) The program should exit if the input is not 1,2 or 3. SPECIFICATIONS: Develop the following functions: Create a function named getTriangleArea which accepts the base and the height and returns the area of the right triangle. Create a function named getTrianglePerimeter which accepts the base and the height and returns the perimeter of the right triangle. Create a function named getRectangleArea which accepts the width and the length and returns the area of the rectangle. Create a function named getRectanglePerimeter which accepts the width and…arrow_forwardUse c++: Enter n numbers stop with sentinel (-1) and show how many and which are odd and even: Example: 29431065 The pairs are 4: 2,4,10,6 The odd ones are 3: 9,3,5 Do not use and, or, functions or arrayarrow_forward

But sometimes London and Toronto switch to daylight savings time on different dates. If Toronto is on daylight savings time and London isn’t, then the time difference is only 5 hours. Conversely, if London is on daylight savings time and Toronto isn’t, the time change is 7 hours. Of course, if both are on daylight savings time, the difference is back to the standard 6 hours. Write a program that takes three lines of input: a float value representing the time in Toronto, whether Toronto is on daylight savings time (1 means yes, 0 means no), and whether London is on daylight savings time (1 means yes, 0 means no). It prints a float giving the time in London. One complication is that you should not print a time greater or equal to 24.0 or less than 0.0. Suggestion: At first don’t consider this complication, and test cases where the…arrow_forwardUSE C++ (Display matrix of 0s and 1s) Write a function that displays an n-by-n matrix using the following header: void printMatrix(int n) Each element is 0 or 1, which is generated randomly.

- C++ Programming Language: Enhance the code given by outputting: The largest number of the sequence a0 ,a1 ,a2 , ..., ak. The position of the largest number Test your program for the following values of x: 75, 111, 678, 732, 873, 2048, and 65535. Example: "For example, for the input sequence: 75, 226, 113, 340, 170, 85, 256, 128, 64, 32, 16, 8, 4, 2, 1, the program output should contain the following: The largest number of the sequence is 340 The position of the largest number is 4" Code Given: #include <iostream> #include <iomanip> using namespace std; int main() { long x; int count; long a_n; cout << "Enter a nonnegative integer: "; cin >> x; cout << endl; count = 0; a_n = x; cout << a_n << ", "; while (a_n !=1) { if (a_n %2==0) a_n = a_n / 2; else a_n = 3 * a_n + 1; count++; cout << a_n <<", "; } cout << endl; cout << "The integer k such that a_k = 1 is " << count << endl; return0; }arrow_forwardC Programming Please: #include <stdio.h> #include <math.h> int main() Write a program to model a simple calculator. Each data line should consist of the next operation to be performed from the list below and the right operand. Your Accumulator's initial value SHOULD be 0. You need a function scan_data with two output parameters that returns the operator and right operand scanned from a data line. You need a function do_next_op that performs the required operation and saves the value in accumulator. do_next_op takes in the operand, value and accumulator. The valid operators are: + add e.g input => + 5.0 - subtract e.g input => - 5.0 * multiply e.g input => * 5.0 / divide e.g input => / 5.0 ^ power e.g input =>^ 5.0 q quit e.g input => q 0 Note: Numbers in your output should be rounded to 1 decimal place.

There are only 4 possible cases for this mission: if the largest digit is the first digit, print "Leftmost" if the largest digit is the third digit, print "Middle" if the largest digit is the last digit, print "Rightmost" if none of the above is correct, print "Unknown" Now, show me how far you've understood your lessons!
