comparesstring1to string2. It is a value returning function that returns a negative integer if string1 < string2, 0 if string1 == string2, and a positive integer if string1 > string2. Write a program that reads two names (last name first followed by a comma followed by the first name) and then prints them in alphabetical order. The two names should be stored in separate character arrays holding a maximum of 25 characters each. Use the strcmp() func- tion to make the comparison of the two names. Remember that 'a' < 'b', 'b' < 'c', etc. Be sure to include the proper header file to use strcmp().

The following functions are all intended to check whether a string representing a dna sequence contains any characters that are not 'a','c','g','t', 'A', 'C', 'G', or 'T'. At least some of these functions are wrong. Which ones are correct? A) def valid_dna1(dna): for c in dna: if c in 'acgtACGT': return True else: return False B) def valid_dna3(dna): for c in dna: flag = c in 'acgtACGT' return flag C) def valid_dna4(dna): for c in dna: if not c in 'acgtACGT': return False return True -------------------------------------------------------------------------------------------------------------------------------------------------------- valid_dna1 only valid_dna4 only None of them. valid_dna1, and valid_dna4 only

Declare a function named contains_char. Its purpose is when given two strings, the first of any length, the second a single character, it will return True if the single character of the second string is found at any index of the first string, and return False otherwise.

Using the provided 3 char airport codes, create a 6 character string that is the origin & destination city pair. Create all the possible...

Game of Hunt in C++ language Create the 'Game of Hunt'. The computer ‘hides’ the treasure at a random location in a 10x10 matrix. The user guesses the location by entering a row and column values. The game ends when the user locates the treasure or the treasure value is less than or equal to zero. Guesses in the wrong location will provide clues such as a compass direction or number of squares horizontally or vertically to the treasure. Using the random number generator, display one of the following in the board where the player made their guess: U# Treasure is up ‘#’ on the vertical axis (where # represents an integer number). D# Treasure is down ‘#’ on the vertical axis (where # represents an integer number) || Treasure is in this row, not up or down from the guess location. -> Treasure is to the right. <- Treasure is to the left. -- Treasure is in the same column, not left or right. +$ Adds 50ドル to treasure and no 50ドル turn loss. -$ Subtracts...
