Assume that word is a variable of type string that has been assigned a value. Assume furthermore that this value always contains the letters “”dr”” followed by at least two other letters. For example: “undramatic”,”dreck”, “android”, “no-drip”. Assume that there is another variable declared, drWord, also of type string. Write the statements needed so that the 4-character substring word of the value of word starting with “dr” is assigned to drWord. So, if the value of word were ” George slew the dragon” your code would assign the value “drag” to drWord.
