Code in Objective C 2008 Does not compile

I'm learning the basics of objective-C by Reading 'Objective C For Dummies'. I'm using XCode 4.4, and I'm trying to get some simple code to work. This question has been posed online before. However - the code doesn't seem to compile with the new version of XCode.

At issue seems to be the line NSLog (@"Here is some amazing text! %i",c); This throws an 'Expected Expression' Error. Per the previous form posting, I have disabled automatic reference checking in preferences and this still fails.

#include <stdio.h>

int main(int argc, const char * argv[])
{

    //declare variables
    int a;
    int b;
    int c;

    //set the variables
    a = 2;
    b = 3;

    //Perform the computations
    c = a % b;

    //Output the results
    NSLog (@"Here is some amazing text! %c",c);

    return 0;
}

Add #import <Foundation/Foundation.h> at the top, and change the NSLog to this:

NSLog (@"Here is some amazing text! %d",c);

Because %c doesn't mean "a variable called c", but rather a char. %d means an int, which is what c is.

You forgot to include the Foundation header:

#import <Foundation/Foundation.h>

Sidenote: The format specifier should be %d.
