switch statement clarification/error

[magadavixt]

heey, here's a code i made to test the switch statements but i'm not sure what went wrong!

/*

4-10 if-else-if vs. switch 
Set up something that uses a switch statement and an if-else-if to do exactly the same thing.
*/

#include <iostream>
#include <string>
using namespace std;

void main()
{
	string cool;
	string y;
	string n;
	
	cout << " If you type y, I will tell you you're cool. If you type n, I'll tell you you're not. <y/n> : ";
	cin >> cool;

	if (cool == "y")
	{cout << "You're Cool.\n";}
	
	else if ( cool == "n")
	{cout << "You're not cool.\n";}
	
	else 
	{ cout << "You didnt put a y or an n.\n";}

	cout <<  "I will do the same thing using a switch.\n";

	switch (cool)
	{
	case y:
		cout << "You're Cool.\n";
		break;
	case n:
		cout << "You're not Cool.\n";
		break;
	default:
		cout << "You didnt put a y or an n.\n";
		break;
	}

	
	system ("pause");
}

IN c++ main return int
int main()

ohhh. so apparently, i cant use strings with case. how would i change the strings into int?

[Lio]

I thing is beter to use char and cast it to int

#include <iostream>
#include <string>
using namespace std;

int main()
{
	char cool;
    cout << " If you type y, I will tell you you're cool. If you type n, I'll tell you you're not. <y/n> : ";
	cin >> cool;
	int choice=static_cast<int>(cool);

    switch (cool)
	{
	case 121:
		cout << "You're Cool.\n";
		break;
	case 110:
		cout << "You're not Cool.\n";
		break;
	default:
		cout << "You didnt put a y or an n.\n";
		break;
	}

}

No, it's better to use char, period.

char cool;
//...
switch(cool){
case 'y':
  //..
case 'n':
  //...
default:
  //...
}

BTW, you aren't using 'choice'

ne555 , i thought the cases cant be letters, but have to be a number/constant!

edit: would i use a stringstream?
