2. Ch1  Get started with Object C on Mac OS X

 

2.1  First simple program in Object C

// First program example
#import <stdio.h>

int main (int argc, const char *argv[])
{
    printf ("Programming is fun.\n");
    
    return 0;
}

 

Notice for C/C++ programmers:

(1) #import instead of #include in ordinary C++ or C files;
(2) When building this kind of object-c file, *.m, use gcc like this:
gcc filename -o objectname -l objc

 Option: -l objc means to specify current build language is "object c"
