while循环的输出不正确

Question

该函数要求loLimit和hiLimit之间的整数，并允许用户安全地输入它。它会一直询问，直到用户在合法范围内输入一个数字。然后它返回合法的号码。

The correct output should be: 
Please enter an integer between 32 and 127: 19 
Please enter an integer between 32 and 127: 128 
Please enter an integer between 32 and 127: 48 
Please enter an integer between 48 and 127: 47 
Please enter an integer between 48 and 127: 65 

但是，我的输出行为奇怪，好像loLimit值来回变化。此外，输入两次后才会记录数字。

Please enter an integer between 32 and 127: 2 
Please enter an integer between 32 and 127: 150 
Please enter an integer between 32 and 127: 56 
Please enter an integer between 32 and 127: 56 
Please enter an integer between 56 and 127: 66 
Please enter an integer between 32 and 127: 66 
Please enter an integer between 66 and 127: 77 

这里是我的代码：

int enterNumber (int loLimit, int hiLimit){ 
    int min; 
    int max; 

    do { 
    printf("Please enter an integer between %d and %d:\n", loLimit, hiLimit); 
    scanf("%d", &min); 
    } 
    while (min<loLimit || min>hiLimit); 
    return min; 
} 

int main(){ 
    enterNumber(32,127); 
    int min=enterNumber(32,127); 

    enterNumber(min,127); 
    int max=enterNumber(enterNumber(32,127),127); 


}

您调用enterNumber（）函数5次，5个接受的值取：通过删除第一

enterNumber(32,127); 
    Please enter an integer between 32 and 127: 56 
    1st accepted number 

    int min=enterNumber(32,127); 
    Please enter an integer between 32 and 127: 56 // 2nd one 
    2nd accepted number 

    enterNumber(min,127); 
    Please enter an integer between 56 and 127: 66 
    3rd accepted answer. 

    int max=enterNumber(enterNumber(32,127),127); //called twice 
    Please enter an integer between 32 and 127: 66 
    Please enter an integer between 66 and 127: 77 
    4th and 5 th accepted answer 

您可以矫正你的逻辑并显示第三次enternumber调用。

int enterNumber (int loLimit, int hiLimit){ 
    int min; 
    int max; 

    do { 
     printf("Please enter an integer between %d and %d:\n", loLimit, hiLimit); 
     scanf("%d", &min); 
     } 
    while (min<loLimit || min>hiLimit); 
    return min; 
    } 

    int main(){ 
// enterNumber(32,127); comment out this 
    int min=enterNumber(32,127); 

    // enterNumber(min,127); 
    int max=enterNumber(min,127); 
    int no=enterNumber(min,max); 

}

首先，它接受一个最小值，则在最大值和最终进入这个范围之间无。
