。副本
count字符的对象所指向的src指出，dest的对象。对象可以重叠：复制发生，如果字符被复制到一个临时字符数组，然后被复制的字符从阵列到dest。如果对象是不平凡的拷贝（标量，数组，C风格的结构），该行为是未定义.Original:
Copies
count characters from the object pointed to by src to the object pointed to by dest. The objects may overlap: copying takes place as if the characters were copied to a temporary character array and then the characters were copied from the array to dest. If the objects are not trivially-copyable (scalars, arrays, C-style structs), the behavior is undefined.The text has been machine-translated via Google Translate.
