Which among the following is Copying function?Select one:a.memcpy()b.strcopy()c.memcopy()d.strxcpy()

Break Down the Problem

1. Identify the options provided.
2. Determine which function serves as a copying mechanism in programming.

Relevant Concepts

• The memcpy() function is a well-known function in the C standard library used to copy a specified number of bytes from one memory location to another.
• The strcpy() function is also used to copy strings in C.
• The other functions (strcopy, memcopy, strxcpy) do not correspond to standard library functions.

Analysis and Detail

1. memcpy(): Copies a block of memory from one location to another. The prototype is void *memcpy(void *dest, const void *src, size_t n);
2. strcopy(): Not a standard function in C; likely a misrepresentation of strcpy().
3. memcopy(): Not a standard function in C; there is memcpy(), but this is not it.
4. strxcpy(): Not a standard function in C; not recognized as part of the standard library.

Verify and Summarize

The option that corresponds to a copying function as per C standards is memcpy(), which is specifically designed for memory copying. The other options listed either do not exist or are incorrect representations.

Final Answer

a. memcpy() is the correct answer.
