任何人都可以重写C程序而不使用do while循环吗？

问题描述

#include <stdio.h>
int main()
{
    int number = 0;
    int pid,status;

    printf("Please enter a number n");
    scanf("%d", &number);

       if(number < 0)
    {
          printf("Please enter a positive number, greather than 0 n");
      scanf("%d", &number);
    }

    pid = fork();

    if(pid < 0)
    {
      printf(" Unsuccessful to create Child Process n");
      exit(-1);
    }

    else if(pid == 0)
    {
             do
        {
        if(number%2 != 0)
        {
          number = (number*3)+1;
                }

        else if(number%2 == 0)
        {
          number = number/2;
        }

        printf("%d n",number);
        }while(number != 1);
    }

    else
    {

        printf("pid %d n",pid);
    printf("Waiting on child process to finish n");
      wait(&status);
      }


return 0;
}
