How to write c++ simple input and output program?

C++ simple input and output program
#Beginner
Cin>> use for get input for keybord
Cout<< display output

In turbo c++ complier


#include<iostream.h>
#include<conio.h>

int main()
{
clrscr();
cout<<"enter your number :";
int number;/* integer variable to store input */
cin>>number;
cout<<endl<<"you number is : "<<number;/* to show input to output */
getch();
return 0;
}

In gcc c++ compiler


#include<iostream>
#include<conio.h>

int main()
{
clrscr();
std::cout<<"enter your number :";
int number;/* integer variable to store input */
std::cin>>number;
std::cout<<std::endl<<"you number is : "<<number;/* to show input to output */
getch();
return 0;
}

In gcc c++ compiler using namespace std


#include<iostream>
#include<conio.h>
using namespace std;

int main()
{
clrscr();
cout<<"enter your number :";
int number;/* integer variable to store input */
cin>>number;
cout<<endl<<"you number is : "<<number;/* to show input to output */
getch();
return 0;
}

Output

enter your number :12345678

you number is : 12345678

(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 ...
