Anyone expert in c++

Explain how one can determine if two prime numbers are twin prime. Twin primes are consecutive prime numbers, for example 1 and 2, 2 and 3, 3 and 5, 5 and 7, 7 and 11, etc Any help on this

Do you help each other in c++ oop?

Given a String with numbers and operators. Perform the operation on the numbers in their respective order. Operator precedence need not be considered. The input string will have the numbers followed by the operators. Input: "12345 * + - + " Result: 6 [Explanation: 1 * 2 + 3 - 4 + 5 = 6] Input: "374291 - - * + -" Result: -8 [Explanation: 3 - 7 - 4 * 2 + 9 - 1 = -8] Guys can you help

s = list(input().split()) num = [] e = [] for i in s: if i.isdigit(): num.append(i) else: e.append(i) num = num[::-1] result = 0 final = 0 for i in e: a = int(num.pop()) b = int(num.pop()) if i == '*': final = a * b num.append(final) elif i == '/': final = a / b num.append(final) elif i == '-': final = a - b num.append(final) else: final = a+b num.append(final) print(num[-1])

Yeah 😅

s = list(input().split()) num = [] e = [] for i in s: if i.isdigit(): num.append(i) else: e.append(i) num = num[::-1] result = 0 final = 0 for i in e: a = int(num.pop()) b = int(num.pop()) if i == '*': final = a * b num.append(final) elif i == '/': final = a / b num.append(final) elif i == '-': final = a - b num.append(final) else: final = a+b num.append(final) print(num[-1])

I know but..

Help me

You'll get banned, stop being an idiot, delete the code and PM me if you need help so desperately.

Hi Tazz, its funny but I am desperate for some answers too. Lol. Can I give you a dm of my concern please?

Write a C ++ program that contain the following functions Function called Average that returns the average of even numbers in the array Function called Shift that Shift the array right one elementExIf the array is 2,3,8,1,0,6,3, after shifting the array will be 9,2,3,8,1,0,6,3,4,! • Function called Replace that replace elements of the array by entered value Ex. If the array is 1,5,2,8,1,6,1,5,9, and the user enter 1 and 20 then the array will be 20,52,8,20,6,20,594. Function called is Armstrong that take an integer array and Boolean array and fill the boolean array by true or false if the corresponding number is Armstrong or not Hint: Armstrong number is a number that is equal to the sum of cubes of its digits(unspecified number of digits)For example 153 is Armstrong numbers because 1^ * 1^ * 1+5*5*5+3*3*3=153 . if the array is \ 153,12,1259,3\ 0\ , boolean array will be \ 3,0,0,3\ In the main define an array called numbers with size 10 and fill it by the user then call Average and Shift function Enter 2 values and Replace function Define boolean array called Armstrong and call isArmstrong function finally print the array after calling functions and print boolean array

Hi everybody. I'm trying to write a predicate function that test if a number is perfect. When I call it, main function return a nonzero value and I get nothing at output. What's wrong? #include <iostream> using namespace std; bool isPerfect (int); int main() { cout<<isPerfect(28); return 0; } bool isPerfect (int number) { int sum = 0; for(int i = 0; i < number/2; i++) { if(number%i == 0) sum += i; } return number == sum; }

In isPerfect, you are starting from i=0 and then calculate number%i where i is 0. This is Undefined behavior. Change it. Main function would print 1 in this case as a boolean true value is interpreted as 1 in the cout statement. If you want to see true or false, include <iomanip> and change the statement containing cout to cout << boolalpha << isPerfect(28);

what the output u want to br

The ouput would be 0 or 1. true or false if I use manipulators. But I was deviding a number by 0 at i = 0.

Can some one solve that??

Yes, someone can... but can you?

No

Sad... you should be able to do it because it is your assignment.

I stdy program c++ new, I dont have many informations about this program

So I would recommend you start it and when you get stuck we could help you out... this way you'll learn.

Create a C++ base class Shape. Derive three different classes Circle, Sphere and Cylinder from shape class. Write a C++ program to calculate area of Circle, Sphere and Cylinder. (Use pure virtual function).

anyone here helping solving programs??

First try yourself, if you have any doubts then ask

Create a C++ base class Media. Derive two different classes from it, class NewsPaper with data members N Name, N Editor, N_Price, No of Pages and class Magazine with data members M Name, M_Editor. M_Price. Write a C++ program to accept and display information of both NewsPaper and Magazine. (Use pure virtual function)

Write a C++ program to create a class Distance with data members meter and centimeter to represent distance. Write a function Larger( ) to return the larger of two distances. (Use this pointer)

I don't have idea about c++... If it was related to c then maybe I helped... It'll be better if you search for one hour oops tutorial of c++ and made by yourself....

Yes copying wont help because these concept are must to learn
