Objective C Hello World

In this section I will show you how to develop Objective C Hello World program. In the next section I will show you how to compile and execute the Objective C Hello World example on windows machine.

Create first objective-c program ?hello.m?

This is a simple program to print Hello, World!

#include <stdio.h>

int main(void)
{
        printf("Hello, World!");
        return ;
}

Save this program with .m extension here 'hello.m' in newly created directory c:/objectiveC.

On the unix or Mac OS x machine save the file in any of your favorite directory. In the next section we will show you how download and install GNU c compiler on your windows machine to compile the application. GNU compiler can be used to compile the Objective C programs.
