Number:          75
Decimal number:  75
  

Test the program with the input letter   a   and copy the results into a comment at the end of your code:
/* Execution Results:
  Put the results here.
*/
Test the program again with the input letter   A   and copy these results below the first execution results.

Print the completed program with both execution results.

Answer 1

#include <iostream>

using namespace std;

int main() {
    char letter;
    int number;
    double decimalNumber;

    cout << "Enter a letter: ";
    cin >> letter;
    number = letter;
    decimalNumber = letter;

    cout << "Character:       " << letter << endl;
    cout << "Number:          " << number << endl;
    cout << "Decimal number:  " << decimalNumber << endl;
    return 0;
}

/* Execution Results:
Character:       a
Number:          97
Decimal number:  97
*/

/* Execution Results:
Character:       A
Number:          65
Decimal number:  65
