Please answer this question correctly in C++.
Write a function, removeLeading, which removes the first n characters from a C-string, str. You may use another C-string but you cannot use a variable of type string. No built-in functions can be used. The function has the following heading:
void removeLeading (char str[], int n)
Assume that the C-string has no more than 100 characters and that n ? strlen (str).
Examples: Suppose str is “abcdefgh”. After the call, removeLeading (str, 3), str should be “defgh”. Suppose str is “abcdefgh”. After the call, removeLeading (str, 5), str should be “fgh”.
