//Loops

//For loop
     for (int y = 0; y < 3; y  ) {
     NSLog(@\"y = %i\", y);
}

//Do loop
x = 0;
do{
     NSLog(@\"x = %i\", x);
     x  ;
}
while(x <= 4);

//While loop
x = 0;
while (x <= 4 ) {
     NSLog(@\"x = %i\", x);
     x  ;
}

//For each loop
//Create an array and add elements to it
NSMutableArray *anArray = [[NSMutableArray alloc] init];
[anArray addObject:@\"Element 1\"];
[anArray addObject:@\"Element 2\"];
[anArray addObject:@\"Element 3\"];

//Use a for each loop to iterate through the array
for (NSString *s in anArray) {
     NSLog(s);
}
//Release the array
[anArray release];
