1. (15 pts) Write a function called my_str_cpy_variant ) that accep e a string). This function eed apointer to a source character array (which is assumed to positions (including 0) in the source character array to the destination character array. If a null character is encountered, then copying must stop. A null character must always be appended to the end of the destination array. For example: to copy only the characters from the even numbered Source array: Index: 4 10 Contents: Destination array: Index: Contents: 2 10' Note: you may use array or pointer notation in this function. Precondition: The destination array must have enough space allocated to accommodate all copied characters, including the null character. Hint: Consider using the strlen () function to help solve this
