This question was caused by a problem that can no longer be reproduced or a simple typographical error. While similar questions may be on-topic here, this one was resolved in a manner unlikely to help future readers. This can often be avoided by identifying and closely inspecting the shortest program necessary to reproduce the problem before posting. Fill in the missing part to create a greeting variable of type string and assign it the value Hello. Copies the first num characters of source to destination. No null-character is implicitly appended at the end of destination if source is longer than num.
