C语言中常用的基本数据类型有:char、short、int、long、float、double: 2.无符号数据类型 在上述整型数据类型前加上unsigned,则为无符号类型: 3.整型数据别名 为了代码编写和阅读方便,我们通常会将数据类型名称声明为简写方式,即uin8_t/uint16_t/uint32_t/uint64_t,或者UINT8/UINT16/UINT32/UINT64。因此uin*...

在C++中,将std::string转换为uint64_t可以通过几种方法实现。下面我将详细解释这些方法,并附上相应的代码片段: 使用std::stoull函数: std::stoull是C++标准库中的一个函数,用于将字符串转换为unsigned long long类型。在大多数情况下,unsigned long long与uint64_t是等价的(尽管具体类型定义可能依赖于编译器和平...
