Help needed with fork operation

Code:

#include<stdio.h>
#include<stdlib.h>
main(void)
{
    if(fork())
    {//parent process
        printf("Parent process\n");
        printf("par:%d\n",getpid());
    }
    else 
    {//child process
        printf("Child process\n");
        printf("Child :%d    Parent:%d\n",getpid(),getppid());
    }
}

When we use fork() function, a child process is created. In this case what will status of 'program counter' of a child process (when started).

I know that the child process contains the code of else block,but I don't know why it is so.

Code:

#include<stdio.h>
#include<stdlib.h>
main(void)
{
printf("ID:%d\n",getpid());
    if(fork()==0)
    {//exclusively child is created?
    printf("par:%d    child:%d\n",getppid(),getpid());
    }
}

In the above code, how the contents of the if block belongs to a child process.

Upon successful completion, fork() shall return 0 to the child process and shall return the process ID of the child process to the parent process

That's why the code in the if block is executed by the child process, but not by the parent. Does it answer your question?
