Rewrite program 10.1

Carefully look at the coded IF statements. All the IF statements between lines 13-22 are executed. But if you think about it, some cases are mutually exclusive or otherwise do no apply when other conditions are true.

Rewrite the program using ELSE statements and/or nested IF statements. The code should not execute an IF statement that it logically does not need to. However, the runtime results should be the same as the original program.

Deliverable is cpp program and either (a flow chart or pseudo code or both).

program 10.1

// This program demonstrates some character-testing functions.

#include <iostream>

#include <cctype>

using namespace std;

int main()

{

char input;

cout << "Enter any character: ";

cin.get(input);

cout << "The character you entered is: " << input << endl;

if (isalpha(input))

cout << "That's an alphabetic character.\n";

if (isdigit(input))

cout << "That's a numeric digit.\n";

if (islower(input))

cout << "The letter you entered is lowercase.\n";

if (isupper(input))

cout << "The letter you entered is uppercase.\n";

if (isspace(input))

cout << "That's a whitespace character.\n";

return 0;

}
