memcpy拷贝数组

memcpy函数用于将源数组的内容拷贝到目标数组中。它的原型是void *memcpy(void *dest, const void *src, size_t n),参数dest表示目标数组的起始位置,src表示源数组的起始位置,n表示要拷贝的字节数。 = {0, 1, 2, 3, 4};
int b << " ";
}
return 0;
}
```
在这个示例中,我们首先定义了两个整型数组a和b。然后使用memcpy函数将a数组的内容拷贝到b数组中,拷贝的字节数由sizeof(a)决定。最后,我们使用循环遍历b数组并打印其内容。输出结果为0 1 2 3 4,即成功将a数组的内容拷贝到了b数组中。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
