Taking input into an array

[kohdurr]

Hello, this is my first post. I started off learning C++ then moved to Objective-C for iOS development. I have a pretty n00b question. Basically, I want to accept a users input and then store that input as part of an array (NSMutableArray). What would be the best way to go about this?

The code below is what I am currently working on to familiarize myself with Obj-c. It is a very basic program, sorry for the messy code.

The issue I am talking about happens at the very end of the code, the rest is just me having fun with conditional statements.

#import <stdio.h>
#import <Foundation/NSArray.h>
#import <Foundation/NSString.h>
#import <Foundation/NSAutoreleasePool.h>
#import <Foundation/NSEnumerator.h>
#import "Fraction.h"
#import "Age.h"
#import "Color.h"

int main ( int argc, const char *argv[] ) {
    //create a new instance
    Fraction *frac = [[Fraction alloc] init];
    Fraction *frac2 = [[Fraction alloc] init];
    
    //set the values
    [frac setNumerator: 1];
    [frac setDenominator: 5];
    [frac2 setNumerator: 7];
    [frac2 setDenominator: 9];
    
    //print it
    printf( "The fraction is: " );
    [frac print];
    printf( "\n" );
    [frac2 print];
    printf( "\n" );
    
    //print conditional statement
    if ( [frac denominator] == 5 ) 
    {
        printf( "Wowza\n" );
    }
    else 
    {
        printf( "WRONG!!" );
    }
    
    //free memory
    [frac dealloc];
    [frac2 dealloc];
    
    //set the age value
    Age *yourAge = [[Age alloc] init];
    int b;
    
    //print statement
    printf( "What is your age?\n" );
    scanf ( "%i", &b );
    [yourAge setAgeOfPerson:b];
    [yourAge printAge];
    [yourAge dealloc];
    
    //array
    NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
    Color *difColor = [[Color alloc] init];
    NSMutableArray *newColors = [NSMutableArray array];
    newColors = [NSMutableArray arrayWithObjects:@"green", nil];
    NSString *yourColor;

    printf( "What is your favorite color?\n" );
    
    scanf( "%i", yourColor );
    
    [newColors addObject: &yourColor];
    
    
    NSLog( @"%@", newColors );
    
    //free memory
    [difColor dealloc];
    [newColors release];
    
    //drain pool
    [pool release];
    return 0;
}

Never ever ever ever ever call dealloc on an object directly. Call release and if the retain count is 0, it's dealloc method will be called.

Thanks for the advice, I didn't know that was improper.

Any suggestions on storing user input into an array? It's a simple enough concept but I can't seem to get it to work.
