c - 如何加入 while 循环和 if 语句的字段

Question

我在 while 循环和 if 语句中分别使用几乎相同的语句或操作，因为它们的条件相反；我可以做些什么来将相同语句的数量从两个减少到一个，我提到的一段代码如下

你能帮帮我吗

 while(current1!=*head1)
    {
        int new_carpim=(current2->number)(current1->number);
        int updateResult=new_carpim+current3->number;

        if(updateResult==2)
        {
            carry_happend(*head3,current3);

        }

        else
        {
            current3->number=updateResult;
        }

        current1=drive_temp(*head1,temp1,current1);
        current3=drive_temp(*head3,temp3,current3);


    }

    if(current1==*head1)
    {
        int new_carpim=(current2->number)(current1->number);
        int updateResult=new_carpim+current3->number;

        if(updateResult==2)
        {
            carry_happend(*head3,current3);

        }

        else
        {
            current3->number=updateResult;
        }

Answer 1

 while(1) //1 = true = (current1==*head or current1!=*head)
    {
        int new_carpim=(current2->number)(current1->number);
        int updateResult=new_carpim+current3->number;

        if(updateResult==2)
        {
            carry_happend(*head3,current3);

        }

        else
        {
            current3->number=updateResult;
        }

        if(current1==*head1){
               break;
        }

        current1=drive_temp(*head1,temp1,current1);
        current3=drive_temp(*head3,temp3,current3);


    }

更一般地说:

while (condition1 || condition2){  //if condition1 || condition2 == true, make sure to break the loop
     if(condition 1)
            //do something for c1
     else if (condition2)
            // do something for c2
     //do something for either c1 or c2
}
