How to create a C++ program to input a character and print out value using static_cast?

Question

Write a program inputs a character (char). Then using a type conversion (static_cast) print out
the integer value of the letter. What happens if you add 1 to a character variable? Print out the
results.

ABOVE is the direct instructions of what i am working on. What is confusing me is, if I make a program to input a character what exactly am i doing? please help if you can.
Below is what I have written thus far.

int main()
{
char a;
char letter = 'a';

cout << "Please enter a character: ";
cin >> a;

letter = letter;

cout << "output" <<endl;

}
