Explanation / Answer

Here I am assuming that the languarge of implementation is C++

1)

Code:

#include <iostream>
#include <cstdlib>

using namespace std;

int main ()
{
int no_of_gallons;
float litres_amt; //final amount in litre
cout<<"Please enter the number of gallons of gasoline"<<endl;
cin>> no_of_gallons; //reading from user
cout<<"Original number of gallons is: "<< no_of_gallons<<endl;
litres_amt = 3.7854 *no_of_gallons;//calculating amount in litre
cout<<no_of_gallons<<" gallons is the equivalent of "<<litres_amt<<"litres "<<endl;
cout<<"Thanks for playing";
}

Sample Input and Output:

Please enter the number of gallons of gasoline
100
Original number of gallons is: 100
100 gallons is the equivalent of 378.54litres

2)

code:

#include <iostream>
#include <cstdlib>

using namespace std;

int main ()
{
char c;
cout<<"Please enter the initial character of your first name"<<endl;
cin>> c; //reading from user
cout<<" "<<c<<" "<<endl;
cout<<" "<<c<<" "<<c<<endl;
cout<<" "<<c<<" "<<c<<endl;
cout<<" "<<c<<" "<<c<<" "<<endl;
cout<<c<<c<<c<<c<<c<<c<<c<<c<<c<<endl;
}
