*Dest++ = *Source++;

This is a simple assignment statement in C programming language, where the value stored in the memory location pointed to by the pointer variable "Source" is assigned to the memory location pointed to by the pointer variable "Dest".

In other words, it means that the data at the memory location pointed to by the pointer variable "Source" is copied to the memory location pointed to by the pointer variable "Dest". After this statement is executed, both "Dest" and "Source" will point to the same memory location with the same data.

这是一段注释，说明了一个函数的作用。这个函数名为USBD_MemCopy，用于在 USB SRAM 和系统 SRAM 之间进行字节访问。其中，dest 是目标指针，src 是源指针，size 是字节数。该函数会将由 size 和 src 参数指定的数据数量复制到由 dest 参数指定的地址中。具体实现使用了一个 while 循环，每次将 src 指向的字节内容赋值给 dest 指向的字节，并将指针向后移动一位。循环次数为 size，即一共复制了 size 个字节。

*(char*)dest = *(char*)src

*(char*)dest = *(char*)src是一个赋值语句，它将源字符串src的第一个字符的值赋给了目标字符串dest的第一个字符。这段代码是字符串拷贝函数中的一部分，用于将src字符串的内容拷贝到dest字符串中。这个赋值语句的作用是将源字符串的第一个字符复制到目标字符串的第一个字符位置。<span class="em">1</span><span class="em">2</span>
