Example 1 - If Statements and Equations <Foundation/Foundation.h> int times(int value, int by); int main (int argc, const char * argv[]) { NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init]; int value = 1230; NSLog(@"Value: %d", value); NSLog(@"Value: %d", value%500); NSLog(@"Value: %d", value/100); NSLog(@"Value: %d", times(value, 4232)); if (value>1242) { NSLog(@"%d is greater then 1242", value); } else if (value>=1242) { NSLog(@"%d is greater then or equal to 1242", value); } else if (value<1240) { NSLog(@"%d is less then 1242", value); } else if (value<=1240) { NSLog(@"%d is less then or equal to 1242", value); } [pool drain]; return 0; } int times(int value, int by) { int returnValue = value*by; return returnValue; } Example 2 - Classes and Methods <Foundation/Foundation.h> "MGMCalculation.h" int main (int argc, const char * argv[]) { NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init]; MGMCalculation *calculation = [[MGMCalculation alloc] init]; [calculation setAmount:572]; [calculation setCurrencyExchange:3]; int amount = [calculation calculate]; NSLog(@"%d", amount); [calculation release]; [pool drain]; return 0; } MGMCalculation.h <Foundation/Foundation.h> @interface MGMCalculation : NSObject { int amount; int currencyExchange; } - (int)amount; - (void)setAmount:(int)theAmount; - (int)currencyExchange; - (void)setCurrencyExchange:(int)theCurrencyExchange; - (int)calculate; @end MGMCalculation.m "MGMCalculation.h" @implementation MGMCalculation - (id)init { if (self = [super init]) { amount = 0; currencyExchange = 0; } return self; } - (int)amount { return amount; } - (void)setAmount:(int)theAmount { amount = theAmount; } - (int)currencyExchange { return currencyExchange; } - (void)setCurrencyExchange:(int)theCurrencyExchange { currencyExchange = theCurrencyExchange; } - (int)calculate { return amount*currencyExchange; } @end Keynote used in this Episode Keynote in PDF Format
