When designing a program, Swapnali, it is important to follow a pattern, or else you may endup with spaghetti code (it will have so many rules for so many cases that no one will know what it does or why). This means that If words start with an uppercase letter, then all words must start with an uppercase letter. If the first letter of a phrase is in lowercase, then all first letters from all phrases should be in lowercase.
