program to implement parent process should wait for return status of child process wait

#include"myHeader.h"
main()
{
int i,status;
if(fork()>0)
{
printf("parent id:%d\n",getppid());
for(i=6;i<10;i++)
{
printf("i=%d\n",i);
sleep(1);
}
wait(&status);
}
else if(fork()==0)
{
printf("child id:%d\n",getpid());
for(i=10;i<25;i++)
{
printf("i=%d\n",i);
sleep(1);
}
}
}
