Strcpy and memcpy

Strcpy and memcpy have the following three differences.

The copied content is different. Strcpy can only copy strings, while memcpy can copy any content, such as character arrays, integers, struct, and classes.

The replication method is different. Strcpy does not need to specify the length. It ends with the string Terminator "/0. Memcpy decides the copy Length Based on its 3rd parameters.

Different purposes. Generally, strcpy is used to copy strings, while memcpy is generally used to copy other types of data.

Header file: # include <string. h>
Define function: void * memcpy (void * DEST, const void * SRC, size_t N)
Function Description: memcpy () is used to copy the first n Bytes of memory content in SRC to the memory address in DeST.Unlike strcpy (), memcpy () completely copies n Bytes and does not end with the string ending '\ 0'.
Return Value: returns the pointer to the DeST.
