在Qt4中创建随机字符串或数字 [英] Create a random string or number in Qt4

问题描述

有没有可以创建完全随机的字符串或数字的功能或类似功能?

Is there any function or something like that by which I can create totally random strings or numbers?

推荐答案

您可以使用 QUuid 类，该类会生成通用唯一标识符.这些不是完全随机的"，但它们是唯一的.

You can create random numbers using qrand. If you need strings, you can convert the int to string. You could also check the QUuid class, which generates Universally Unique Identifiers. Those are not 'totally random', but they are unique.
