我试图制作一段代码，它会在最后掷骰子来决定哪个角色获胜，但它一直说有错误(使用未分配的局部变量'skillmodifier') &(使用未分配的局部变量“strengthmodifier”)。我真的很感激任何帮助。 P.S 我只在 Visual Studio 2010 上做了很短的一段时间的编程。请帮我找到解决这个问题的方法，这个问题是因为我使用变量 'strengthmodifier' 和 'skillmodifier' 两次。谢谢你，你忠实的 Vikash。 我将在下面粘贴任务简介和之后的代码:
任务 3 确定遭遇的结果 当两个角色相遇时，结果由以下决定 过程:
• 计算两个角色的强度属性之间的差异
• 此差异除以 5，然后向下舍入以创建“强度修正值”
• 对技能属性重复该过程以创建“技能修饰符”
• 每个玩家掷一个 6 面骰子。
• 如果两个骰子的分数相同，则不做任何更改
• 如果分数不相同，则得分最高的玩家加上“力量” modifier' 到力量值和 ‘skill modifier' 到他们的技能值 性格
• 骰子得分较低的玩家从 他们性格的力量和技能值
• 如果技能值变为负数，则将其存储为零
• 如果强度值变为零或负数，则角色死亡。
程序应该:
*• 允许用户输入两个角色的力量和技能。
• 使用上述过程显示遭遇的结果。 设计一个算法来描述这个过程。编写、测试和评估代码。*

最佳答案
实际上，我认为你的问题是因为 skillmodifier 和 strengthmodifier 没有在所有代码路径上获得赋值。 IE。它们仅在 if 子句和 visual studio 无法确定是否为所有可能的结果分配了值。这个警告不应该停止你的代码编译，但如果你想让它消失，你可以做类似的事情
int skillmodifiertoround = 0;
不仅仅是
int skillmodifiertoround;
现在 skillmodifiertoround 在声明时被赋予了一个值。
编辑:“这个警告不应该停止你的代码编译”——显然它会阻止程序在 c# 中正确编译，但在 vb 中同样的错误只给出警告但仍然编译。
