What Is Wrong With Xcode

Wrong Apple ID in Xcode?

I just started using Xcode, and I did the "hello world" tutorial app for iOS. I tried running it on my phone, and it initially said that there was no public/private certificate pair. I fixed that, got both certificates, both are saved on my computer and in my keychain. Now, when I try to add my phone to the "Member Center", it says my Apple ID password is wrong. Now, I didn't change this at any point up until I got this error. Thinking that Xcode might have screwed it up, I typed in my Apple ID password. This is not what Xcode was looking for. I tried some of the other alphabet soup passwords stored in my Keychain as "app passwords"; none of those worked either. I have no idea what password it's looking for. The same password unlocks my macbook, app store, apple ID, all that stuff. Aaaaaaaand... now that's not working I guess. Any ideas?

How the f@%& do I do c++ in xcode?

You can start learning C++ with these video tutorials:
http://xoax.net/comp/cpp/index.php

They are perfect for beginners. This one can get you started by showing you how to install a free compiler:

You can go through the tutorials and if you have questions on them or anything else in C++, please post to me here:

What does Xcode error "expected expression" mean (writing in C++)?

I am new to Xcode. I am writing in C++. In the following bit of my code, on the line that has the closing paren for case 1, Xcode has the error "expected expression." But it doesn't put that error on either of the other lines with only closing parens on them. I also tried just putting the closing paren on the line just after the break statement with the semicolon of course, but the error remained. What am I missing?

Xcode also is giving me an error on the line in case 1 "cout << permutation(n, k) << endl;" that reads "expected ')'." I don't understand what is happening there either. The error goes away when I put an ending paren after the line, but then I can't break the switch statement and of course that opens up a whole other can of worms. Please help.

while (true) {
switch (option) {
case 1: (
cout << permutation(n, k) << endl;
option = 0;
break;
)
case 2: (
cout << endl << combination(n, k);
option = 0;
break;
)
default: (
cout << "Something went wrong with the first entry. Please enter 1 for permutation or 2 for combination. ";
cin >> option;
break;
)

}
if (option == 0) break;
}

C programming: creating files in xcode?

I am working on another assignment: write a program that sequentially displays on screen the contents of all of the files listed in the command line. Use argc to control the loop. Below is my code. The reason why I can't check it is because I don't know how to create a file in xcode or at least not in the way that is required for this program. I tried from the main terminal (I am working on a mac) creating files but the program doesn't read them. Either the program is wrong or the files are not saved in the command line. I am a beginner with almost no experience so I would really appreciate some help, thank you!

#include
#include

int main (int argc, char * argv[])
{
char ch;
int i;
FILE *fp;

for(i = 0; i < argc; i++)
if((fp = fopen(argv[ 1 ],"r"))==NULL) {
printf("Cannot open file.\n");
exit(1);
}

while((ch = fgetc( fp )) != EOF) {
printf("%c", ch);
}
fclose(fp);

return 0;
}

What is wrong with the syntax for this class?

For C++, I seem to be having some problems adjusting a bit. I know java, but I need a bit of help with this.

#include

using namespace std;

class object{
private:
int x;
int y;
public:
object(){
x=5;
y=6;
}
int getx(){
return x;
}
int gety(){
return y;
}
~object(){
}
int add(){
int z = x+y;
return z;
}
};

int main(){

object o;

cout << "x: " << o.getx() << endl << "y: " << o.gety() << endl << "a: " << o.add();


cout << o.add();

return 0;
}

I wold expect the output for o.add() to be 11. But this is what I'm getting when I run.

The Debugger has exited with status 0.

x: 5
y: 6
a: 1111
The Debugger has exited with status 0.

What am I doing wrong here? Am I creating the instance correctly? It seems a bit weird to just put object o, compared to java, object o = new object(); :P

Any help appreciated.

Xcode storyboard showing code?

I was coding an app in xcode and i must have pressed a wrong combination or something, because now my storyboard file is showing as if it were a text file, with a lot of code in it. How do I get it back to the default graphical mode?
