write a program to concatenate a c-string to the end of another and submit at this link:

Write the function append that accepts two c-string arguments. the second c-string must be copied on to the end of the first c-string. You may assume the first character array has enough space to hold the additional cstring. Make sure that the first c-string has the proper nul-termation when you are done. You may not use any functions defined in the cstring library.

Write a main program to call append. It must define two character arrays, and initialize both with text. Make sure the first is large enough to eventually contain the data from both arrays. Output both arrays before and after calling append.

i need this in C++

Thanks!
