Write your own memcpy() function in C language

Here we will see how to implement memcpy() function in C language. The memcpy() function is used to copy a block of data from one location to another. The syntax of memcpy() is as follows -void*memcpy(void*dest,constvoid*srd,size_tnum); In order to make our own memcpy, we have to typecast the given address to char* and then copy the data byte by byte from the source to the target. Just read the following code to get a better idea. Example#include<stdio.h>#include<string.h>voidcustom_mem
