In contrast, thestrcpyfunction is used to copy the same string to the buffer array, and automatically adds a null terminator to the end of the copied string. #include <stdio.h> #include <string.h> int main() { char source[] = "Hello, world!"; char buffer[20]; // Use memcpy to...
1. C memcpy C memcpy是C语言中的一个函数,用于在内存中复制一段内存区域到另一个内存区域。它的原型如下: ```c void *memcpy(void *dest, const ...
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...
