c++ - Write a program that asks the user to enter a person's weight in kilograms (kg) and returns the equivalent weight in pounds (lbs) -

write program asks user enter person's weight in kilograms (kg) , returns equivalent weight in pounds (lbs). note 1 kg = 2.2 lbs. program should display 2 values (in kg , lb) rounded 2 decimal places (using header "iomanip" file).

#include <iostream> #include <iomanip>  using namespace std;   int main() {     float p=0;     cout << "enter le weight of personne in pounds : " << p << "\n";     cin >> p;     cout << "the weight of personne : " << 2.2*p << "kg ou " << p << "pounds \n";      return 0;  } 

questions :

1- use library "iomanip" here? how else can do?

2- why program give me 0 on first line once run? wish write result on first line when program executed.

3- program seems comply statement?

do use library "iomanip" here? how else can do?

no not. need output io manipulator std::setw(2) std::cout before p

cout << "the weight of personne : " << setw(2) << p/2.2 << "kg ou " << p << "pounds \n"; 

why program give me 0 on first line once run? wish write result on first line when program executed.

because output p std::cout. change code to:

cout << "enter le weight of personne in pounds : "; cin >> p; 

does program seems comply statement?

after fix it, should
