Domain Types in SQL – Structured Query Language

A user-defined data types in SQL are Domain Type. You can use the domain instead of a built-in SQL data type. To know the difference between user-defined and built-in data types check our post.  You can use the domain instead of a built-in SQL data type when declaring a column. That column will then be restricted only to use the same domain. Some good definitions of Domain type in SQL are found HERE. … Read more

C++ Programming Solutions – Encrypt String

Question Kathy is a scientist who is developing a machine that creates 5-character long string code. She prefers to encrypt the strings rather than save them as they are. She’s requested you to create software that would accept a 5-character string as input and encrypt it in the format she’s provided You must look for the letters in the odd locations of the string and, if they are vowels, you must replace them with  _ (underscore). “hecod” should be “h_c_d”. “progr” should be “progr”. because odd locations  are not vowels. C++ Programming Solution Starting Code in C++ will be Let’s take input from the user If the length of the input is not 5, input is wrong, and take input … Read more
