In gcc c++ compiler using namespace std;

#include<iostream>
#include<ctime>
using namespace std;

int main()
{
int totalsec = time(0);
int currentsec = totalsec % 60;
int totalminutes= totalsec / 60;
int currentminutes=totalminutes % 60;
int totalhrs=totalminutes / 60;
int currenthrs=totalhrs % 24;
int gmt;
cout<<"enter GMT zone -12 to +12 :";
cin>>gmt;
int currentgmthrs=(totalhrs+gmt)%24;
cout<<"main time  "<<currenthrs<<" :"<<currentminutes<<" :"<<currentsec<<" GMT +0"<<endl;
cout<<"your time "<<currentgmthrs<<" :"<<currentminutes<<" :"<<currentsec<<" GMT "<<gmt<<endl;
        return 0;
}
copy

Output
enter GMT zone -12 to +12 :5
main time  11 :17 :49 GMT +0
your time 16 :17 :49 GMT 5

(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 ...

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.

(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]
