- 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. can't figure out what's wrong with my code!Please circle True or False for each of the following statements. C++ The return type void indicates that a function will perform a task but will not return any information upon completion of that task. TRUE FALSEIn C++, State if the following variable names are valid or invalid. If it's invalid, state why. Note: invalid here means creating a syntax error. a) 1wayTicket b) employee_pay c) #zombies d) R66Y e) STOP! f) Final Exam

Given that an int variable s has been initialized, write a statement(s) that declares a new variable andassign it the remainder of 9 times 8 less than s divided by 4. e. Write a statement(s) that initializes the variables named a, b, c and d to false, ''one'', 'y' and 87.9respectivelyC++ programming question: Suppose we have just discovered an alien planet (we will call it Mars), and on this planet one year is divided into 15 months and each month consists of 30 days. i. Write the code for a struct charontime to hold years, months, and days for time on Charon -all ints. ii. Write a function that takes an int parameter that represents the number of Charon days, converts it to years, months, and days on Charon and returns this information in a struct charontime. So for example it will convert 800 days into a struct that represents 1 year, 11 months, and 20 days. iii. Write a function that takes a struct charontime parameter and returns the total number of Charon days represented by the struct. iv. Write a function that takes a filename and an array of struct charontime, opens the file, reads each line as the number of Charon days, converts this to a struct charontime and stores this in the array. (you don't need to create an actual file with number of days in it...…
