您可能希望不断重复，直到获得有效的代码。在这种情况下，请使用

&&

while((speciesCode != 11) || (speciesCode != 12) || (speciesCode != 13) || ...)

---

@CaseyNelms最终将使其停止循环，但看起来您实际上想要

while（（speciesCode！=11）&&&

修复了它，但它仍然在高度上运行我修复了高度，但之后它不断崩溃。这可能是我的calcTotVol函数吗？抱歉，我太迷路了，这是我的最后一次了，它把我撕裂了pieces@CaseyNelms包含六项的数组中的有效索引为0到5。访问第七项索引6未定义，可能导致v发生了非常奇怪的事情。哦，天哪，我觉得自己很愚蠢，但它一直显示一个未处理的异常，而且数字相差很远

while((speciesCode != 11) && (speciesCode != 12) && (speciesCode != 13) && ...)
