Swap the number without using thrid varible or temp c++ program

Swap the number without using thrid varible or temp program
# Beginner

In gcc c++ compiler using namespace std;


#include <iostream>
using namespace std;

int main()
{
int number1, number2;
cout << "enter two number :" << endl;
cout << "number1 : ";
cin >> number1;
cout << "number2 : ";
cin >> number2;
cout << endl;

cout << "number before swaping " << endl;
cout << "number1 : " << number1 << endl;
cout << "number2 : " << number2 << endl;
cout << endl;

number1 = number1 + number2;
number2 = number1 - number2;
number1 = number1 - number2;

cout << "number after swaping " << endl;
cout << "number1 : " << number1 << endl;
cout << "number2 : " << number2 << endl;
}
copy

Output

enter two number :
number1 : 54
number2 : 13

number before swaping
number1 : 54
number2 : 13

number after swaping
number1 : 13
number2 : 54

(Financial application: calculate tips) Write a program that reads the subtotal and  the gratuity rate, then computes the gratuity and total. For example, if the user enters  10 for subtotal and 15% for gratuity rate, the program displays $1.5 as gratuity and  $11.5 as total. #Beginner In gcc c++ compiler using namespace std; #include<iostream> using namespace std; int main() { float total , gratuity_rate ; cout<< " enter sub total and gratuity rate :" ; cin>>total>>gratuity_rate; float gratuity = total*gratuity_rate/100; float final_total = gratuity + total; cout<< "gratuity $" <<gratuity<< " final total is $" <<final_total; return 0; } Output enter sub total and gratuity rate :10 15 gratuity $1.5 final total is $11.5 [Program finished]

(Find the number of years) Write a program that prompts the user to enter the min- utes (e.g., 1 billion), and displays the number of years and days for the minutes. For  simplicity, assume a year has 365 days. #Beginner In gcc c++ compiler using namespace std; #include<iostream> using namespace std; int main() { int minutes; cout<< "enter the minutes : " ; cin>>minutes; const int year_per_minutes=365*24*60; const int day_per_minutes=24*60; int year=minutes/year_per_minutes; int day=(minutes%year_per_minutes)/(day_per_minutes); cout<< " " <<minutes<< " minutes is aproximately " <<year<< " years and " <<day<< " days" ; return 0; } copy Output enter the minutes : 1000000000  1000000000 minutes is aproximately 1902 years and 214 days [Program finished] Need of Programmer Need of Programmer ...
