我一直收到一个警告，关于传递参数使得指针来自整数而没有强制转换

巨大的问题真的很值得帮助教授拒绝提供帮助。晚餐休息后，我一直在盯着这个问题约3个小时。我还是想不出来。如果你可以帮我向我解释这一点，那么我可以了解我做错了什么我会非常感激。

    return range_counter;
 }

答案

get_range(low_number, high_number); => get_range(&low_number, &high_number);

另一答案

函数get_range()需要两个指针。那是因为它将使用这些指针为另一个函数的变量赋值。

您的教授希望您使用此函数来读取在main()中声明的两个变量。所以你必须获取这些变量的地址并将它们传递给get_range()，而不是它们的值。
