For example, you could use memcpy to copy a portion of a source string to a dest buffer or to concatenate two strings together into a new buffer. Arrays: memcpy() can be used to copy the contents of one array to another. This is often useful when working with large arrays that may ...
memcpy(byteArray,&person,sizeof(person)); } 在上述代码中,我们使用了`memcpy`函数将结构体`person`的内容复制到字节数组`byteArray`中。`sizeof`函数用于获取结构体的大小。 3.2 字节数组转换为结构体的成员变量 通过前面的步骤,我们将结构体转换为了字节数组。现在,我们来介绍如何将字节数组转换回结构体的成员...
