Hi All, I want to ask malloc() behaviour, consider these codes; ... char *ptr = malloc(1); strcpy(ptr, "what"); puts(ptr); .... Confusingly, the strcpy() copied all bytes to ptr, but I just manage to allocate ptr only for 1 byte, I guess I will have segfault here, why this happen? why the string successfully copied into ptr? , is those code legal?
