Write a program that prompts the user to enter v in meters/second (m/s) and the acceleration a in meters/second squared (m/s²), and displays the minimum runway length.

(Physics: finding runway length) Given an airplane’s acceleration a and take-off 
speed v, you can compute the minimum runway length needed for an airplane to take 
off using the following formula:
length = v²/2a
 Write a program that prompts the user to enter v in meters/second (m/s) and the accel-
eration a in meters/second squared (m/s²), and displays the minimum runway length.
#Beginner
In gcc c++ compiler using namespace std;

#include<iostream>
using namespace std;

int main()
{
float speed,acceleration,length;
cout<<"Enter speed and acceleration :";
cin>>speed>>acceleration;
length=(float)(speed*speed)/(2*acceleration);
cout<<"The minimum runway length for this airplane is :"<<length;
return 0;
}
copy

Output
Enter speed and acceleration :60 3.5
The minimum runway length for this airplane is :514.286

(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 ...
