Question 5 Write the code for the function printRoster, it should print out the contacts in a format similar to the example. You can use a range-based for-loop and auto to simplify the solution, if you wish. #include #include #include #include #include using namespace std; void printRoster(map>>& roster) { // Fill code here int main() { map>> roster; roster["ELCO"]["CS-30"]. emplace_back("Anthony Davis"); roster["ElCo"]"cS-30"j. emplace_back("Talen Horton-Tucker"); roster["ElCo"Ï"BUS-101"].emplace_back("LeBron James"); roster["SMC"]["CHEM-101"].emplace_back("Russell Westbrook"); printRoster(roster); return 0; Here is the sample output: ElCo BUS-101: LeBron James CS-30: Anthony Davis Talen Horton-Tucker SMC CHEM-101: Russell Westbrook

C++ Code: Write a program that finds word differences between two sentences. The input begins with an integer indicating the number of words in each sentence. The next input line is the first sentence and the following input line is the second sentence. Assume that the two sentences have the same number of words and no more than 20 words each. The program displays word pairs that differ between the two sentences. One pair is displayed per line. Ex: If the input is: 6 Smaller cars get better gas mileage Tiny cars get great fuel economy then the output is: Smaller Tiny better great gas fuel mileage economy Add a function named ReadSentences to read the input sentences into two string vectors. void ReadSentences(vector<string>& sentence1Words, vector<string>& sentence2Words, int wordCount) main() already contains code to read the word count and call ReadSentences(). Complete main() to display differing word pairs.

The show_sequence function at below is part of chapter 3 program. What kind of passing does this function us and why? void show_sequence(sequence display) // Library facilities used: iostream{ for (display.start( ); display.is_item( ); display.advance( )) cout << display.current( ) << endl;} Group of answer choices It uses a value parameter. The reason is the advancing of the current element through the sequence would alter the actual argument. That is what we want. It uses a value parameter. The reason is the we don't want the advancing of the current element through the sequence to alter the actual argument. It uses a geneeral parameter. The reason is the we don't want the advancing of the current element through the sequence to alter the actual argument. It uses a reference parameter.

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 to treasure and no $50 turn loss. -$ Subtracts…
1c) Average sentence length We will create a function (avg_sentence_len) to calculate the average sentence length across a piece of text. This function should take text as an input parameter. Within this function: sentences: Use the split() string method to split the input text at every '.'. This will split the text into a list of sentences. Store this in the variable sentences. To keep things simple, we will consider every "." as a sentence separator. (This decision could lead to misleading answers. For example, "Hello Dr. Jacob." is actually a single sentence, but our function will consider this 2 separate sentences). words: Use the split() method to split the input text into a list of separate words, storing this in words. Again, to limit complexity, we will assume that all words are separated by a single space (" "). (So, while "I am going.to see you later" actually has 7 words, since there is no space after the ".", so we will assume the this to contain 6 separate words in our…
