这是我得到错误的相关代码。如果你需要查看更多我的代码，请告诉我，我会添加它。
我在互联网上寻找解决方案，发现了与我类似的问题，但这些维修工作都没有解决问题。如有任何帮助，将不胜感激
有符号/无符号不匹配。我该如何解决这个问题？
从窄到宽。如果无符号类型更宽，则首先考虑负值。
如果相对宽度不确定，请先处理负值。
NewSBSize.X显然是一个short，一个符号类型。
text.size()是一个size_t，一个无符号类型。
如果NewSBSize.X出乎意料地为负，那么NewSBSize.X > text.size()在逻辑上为假，所以在这种情况下会失败。
if (NewSBSize.X >= 0 && ....
然后将short转换为其无符号对应项，或其无符号升级对应项。此处的强制转换不会对NewSBSize.X进行无值更改，下面的无符号比较基于两个无符号类型中较宽的一个进行。
... (unsigned) NewSBSize.X > text.size()
总计
if (NewSBSize.X >= 0 && (unsigned) NewSBSize.X > text.size()) {
如果代码可以确保NewSBSize.X >= 0，则简化为以下内容
警告：微优化是邪恶的。
if ((unsigned) NewSBSize.X > text.size()) {
