Area and perimeter of an equilateral triangle c++ program

(Area and perimeter of an equilateral triangle) Write a program that displays the 
area and perimeter of an equilateral triangle that has its three sides as 9.2, using the following formula:
area = 1.732 * (side)²/ 4
perimeter = 3 * side

#Beginner
In gcc c++ compiler using namespace std;

#include <iostream>
using namespace std;

int main()
{
float side = 9.2;
float area = 1.732 * side * side / 4;
float perimeter = 3 * side;

cout << "area of the triangle is : " << area << endl;
cout << "perimeter of triangle is : " << perimeter;
return 0;
}
copy

Output

area of the triangle is : 36.6491
perimeter of triangle is : 27.6

(Population projection) The U.S. Census Bureau projects population based on the  following assumptions: 1.One birth every 7 seconds 2.One death every 13 seconds 3.One new immigrant every 45 seconds  Write a program that displays the population for each of the next five years. Assume  the current population is 312,032,486 and one year has 365 days. Hint: In C++, if two  integers perform division, the result is the quotient. The fractional part is truncated. #Beginner In gcc c++ compiler using namespace std; #include<iostream> using namespace std; int main() { long long int   currentPopulation = 312032486;     int perBirth = 7 ; //second ;     int perDeath = 13 ; //second ;     int perImmigrant = 45 ; //second ;          cout<< "enter year to see population : " ;     int year ; cin>>year; //get year          long long int   yearTosecond = yea...

(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 ...

(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]
