The memcpy() function in C and C++ is used to copy a block of memory from one location to another. Unlike other copy functions, the memcpy function copies the specified number of bytes from one memory location to the other memory location regardless of the type of data stored.
It is declared in header file. In C++, it is also defined inside header file.
The memcpy function is declared as:
void *memcpy(void *to, const void *from, size_t numBytes);
Below is the C program to show the working of memcpy()

Note: memmove() is another library function that handles overlapping well.
The memcpy function is used to copy a block of data from a source address to a destination address. Below is its prototype. void * memcpy(void * destination, const void * source, size_t num);The idea is to simply typecast given addresses to char *(char takes 1 byte). Then one by one copy data from source to destination. Below is implementation of t

Vectors are the same as dynamic arrays with the ability to resize themselves automatically when an element is inserted or deleted, with their storage being handled automatically by the container.
