Lab03-11. Write a function that has three C++ strings as parameters. It searches the first parameter to find the second parameter (as a substring) and replaces it with the third parameter. It returns the changed first parameter if the substring can be found; otherwise, it returns the original first parameter. Test your function in a program.

You can write a program in C++ using only one function. At the same time you can break this function into 20 smaller functions calling each other. Which approach is better? Why?

Please in C++, thank you.

3. A programmer implemented a swap function in C as follows: void swap (int x, int y) { int temp; = temp X; x=y; y temp; } However when he tried to use the swap function in the main function as given below, it didn't work. int main () { int a-10, b=20; swap (a,b); Explain why this function doesn't work. Suggest a way of fixing it. i. ii.

Problem Description: Implement the described Mancala variant in C++ in the pictures. Player 1 will be a human while the other will be a computer player. The computer player selects a hole following the following decision logic: If there is a hole with enough pieces to finish the turn in the computer player's end zone, select it. Otherwise select the hole on the right to left path with the greatest amount of marbles. If there are no marbles on that path then select the hole closest to the opponent's end zone. It is highly suggested, but not required, to pause the output after the computer makes a move to allow the user to interpret the output before more gets printed out. Look into cin.get(); The program should not allow the player to enter incorrect selections. The player cannot select a nonexistent hole, the end zones, or an empty hole. Look at the example output for an example for how to output the game board formatted in a nice way. You must tell the player what input is valid. For...

The question should be done in C++, please give explanation and running result. 1. Let’s write a function that compares 2 strings and returns true if they were identical, false otherwise. The signature of this function should be: bool word_diff(std::string word1, std::string word2); For example: std::string str1 = "Hello World";std::string str2 = "hEllO World";std::string str3 = "World";std::string str4 = "Hello World";bool result = word_diff(str1, str2); // Falsebool result = word_diff(str1, str3); // Falsebool result = word_diff(str1, str4); // True 2. Now let’s follow a classical approach to compare the content of 2 files. We should open each file, read their content word by word and compare them until a first mismatch occurs.Let’s implement a function called classical_file_diff that takes 2 arguments each of which is a file name and returns a boolean indicating whether the 2 files are identical or not. The signature of this function should be: bool...

Write a function in C++ that accepts a single number, calculates the number of positive odd numbers below the parameter value and returns the calculated result to the main method.

Working on an assignment for C++ codding. Need a little help. I need to write a function that takes in the user's input and returns true if the input contains "polly", "cracker", or "hello". Thanks in advance!

Write a function in C++ that accepts a student’s final exam grade (worth 40 points) and number of completed projects (each worth 10 points) and returns the calculated final grade (out of 100 points) to the main method.

Pls make a code for this on c++ and make sure it is 100% correct. i wastred 4 questoins on this and they all are not correct. Write the code as described in the questions below. Submit your code electronically in the box at the bottom. You may only use Java, C# or C++. The economy is defined using a 2-dimensional data structure: A "payday" will be considered to be any region of $ values where all cells in the region are connected either vertically or horizontally. For example, the following illustrates a matrix with 5 rows and 8 columns containing three objects. $’s and P are used in the diagram to represent the two types of values: PPPP$PPPPPP$$PPPPP$$PPP$PP$PPPP$P$PPP$$$ a) Write a program to read in the data from the text file and store it into a data structure. Your program should output it to the screen after it has read in the file. (If you can’t get this to work hard-code the above example and continue to part b). Here is a sample text file (containing the above data):...

Write a lisp program (please provide photos that it works)

Suppose that you have the following recursive function written in C++. I've intentionally written the function so that it doesn't use descriptive names for anything, though that's obviously not a good design practice, but I aim not to bias your understanding of the techniques you'll be using by assuming anything about what the function's goal is; to stay "on task" here, you should resist the temptation to try to figure that out first. void kaboom( const std::vector& v, std::vector& w, unsigned int i) { if (i < w.size()) { int q = 0; for (int j : v) { q += j; } w.at(i) - kaboom(v, w, i + 1); } = q; } 1. Using the techniques from our discussion of the Asymptotic Analysis of Recursion, write a recurrence that describes the time required to run the following call to kaboom for two vector v and w whose sizes are the same. Use the variable s in your recurrence to denote that size. kaboom(v, w, 0) 2. Using the repeated substitution technique, reduce the recurrence to a closed form, then give...
