Posted: Thu Aug 20, 2009 3:36 pm Post subject: C++, "jumping" on a else?

Code:

#include "stdafx.h"
#include <iostream>
#include "Chasestest.h"
int main()
{
using namespace std;
cout << "Please enter your number: ";
cin >> x;
cout << "Good, now please enter the second number: ";
shorten();

}
void shorten()
{
using namespace std;
int y;
cin >> y;
int total;
total = x + y;
if (total == 42)
cout << " You have discovered the meaning of life!\n" << x + y;
else if (total <= 12)
cout << "\nWhy enter in such a low number\?\n";
else
cout << "\n You don't know the meaning of life? It's certainly not:\t\t\t" << total;
orange();
}

IS there anyway for me to only make it go to orange ONLY if the "Else" is triggered?

yeah, use brackets { }.

Code:

if (total == 42)
{
cout << " You have discovered the meaning of life!\n" << x + y;
}
else if (total <= 12)
{
cout << "\nWhy enter in such a low number\?\n";
}
else
{
cout << "\n You don't know the meaning of life? It's certainly not:\t\t\t" << total;
orange();
}

I can't see anything wrong with the brackets.

you forgot the last bracket.

Code:

#include "stdafx.h"
#include <iostream>
#include "Chasestest.h"
int main()
{
using namespace std;
cout << "Please enter your number: ";
cin >> x;
cout << "Good, now please enter the second number: ";
shorten();

}
void shorten()
{
using namespace std;
int y;
cin >> y;
int total;
total = x + y;

if (total == 42)
{
cout << " You have discovered the meaning of life!\n" << x + y;
}
else if (total <= 12)
{
cout << "\nWhy enter in such a low number\?\n";
}
else
{
cout << "\n You don't know the meaning of life? It's certainly not:\t\t\t" << total;
orange();
}
}

ps. use indentation, you'll notice it when the brackets don't line up. for every opening bracket there must be a closing one.

Double brackets? hmm, looks like i need to read more on c++ lol

note if it's only one line you can leave out the brackets :

Code:

could be :

Code:

if (total == 42)
cout << " You have discovered the meaning of life!\n" << x + y;
else if (total <= 12)
cout << "\nWhy enter in such a low number\?\n";
else
{
cout << "\n You don't know the meaning of life? It's certainly not:\t\t\t" << total;
orange();
}
