Quick look at "Accepts a pointer to a C-String" What does this mean???

[TheDMinor]

I have made this program run, however in the book it says my functions should "accept a pointer to a c-string as its argument." Please help me if you can.

#include <iostream>
#include <iomanip>
#include <string>

using namespace std;

void vowCounter(string);
void conCounter(string);

int main()
{
	//Definition of str, as well as the menu display
	string str;
	char choice;
	
	do
	{	
		cout << endl;
		cout << "Enter a string: ";
		cin >> str;

		cout << endl;
		cout << "What do you wish to do in the string? " << endl;
		cout << "A) Count the number of vowels" << endl;
		cout << "B) Count the number of consonants" << endl;
		cout << "C) Count both the vowels and consonants" << endl;
		cout << "D) Enter another string instead" << endl;
		cout << "E) Exit the program" << endl;
		cin >> choice;

	
		{
			switch (toupper(choice))
			{
			case 'A':
			{
				vowCounter(str);
				cout << endl;
				break;
			}
			case 'B':
			{
				conCounter(str);
				cout << endl;
				break;
			}
			case 'C':
			{
				vowCounter(str);
				cout << endl;
				conCounter(str);
				cout << endl;
				break;
			}
			case 'D':
			{
				continue;
				break;
			}
			case 'E':
			{
				cout << "Exiting the program....." << endl;
				break;
			}
			default:
			{
				cout << "Input is invalid, try again. ";
				cout << endl;
				break;
			}
				}
			}
	} while (toupper(choice) != 'E');

	return 0;
}

void vowCounter(string str)
{
	char temp;
	int vowelC = 0;

	for (int i = 0; i < str.size(); i++)
	{
		temp = toupper(str[i]);
		switch (temp)
		{
		case 'A':
		case 'E':
		case 'I':
		case 'O':
		case 'U':
			vowelC++;
			break;
		default:
			break;
		}
	}
	cout << "There are " << vowelC << " vowels in the string." << endl;
}

void conCounter(string str)
{
	char temp;
	int consonC = 0;

	for (int i = 0; i < str.size(); i++)
	{
		temp = toupper(str[i]);
		switch (temp)
		{
		case 'A':
		case 'E':
		case 'I':
		case 'O':
		case 'U':
			break;
		default:
			consonC++;
			break;
		}
	}
	cout << "There are " << consonC << " consonants in the string." << endl;
}

What is the title and author of your book?

[TheDMinor]

starting out with C++ from control structures through objects, by tony gaddis

I would be hesitant about any book claiming to teach C++ that requires you to use c-style strings. I would recommend just using std::string as you have already done.

[TheDMinor]

Thought so, thank you for helping. Also, LB would you care to run my program, and help me fix the problem where, if you enter a string with spaces it does not compile right.

[LB]

You could replace line 20 with std::getline(std::cin, str); to read an entire line of input instead of just the first word.

Thank you, I thought I had that, guess I overlooked it lol
